This application claims to be a priority of the prior application of US Patent No. 60/990541 filed on November 27, 2007; Preliminary US Patent Application No. 60/990547 filed November 27, 2007; Preliminary US Patent Application No. 60/990559 filed November 27, 2007; Preliminary US Patent Application No. 60/990513 filed on November 27, 2007; Preliminary US Patent Application Ser. No.60 / 990564 filed November 27, 2007; and the most recent US Patent Application Serial No. 60/990570, filed November 27, 2007, the contents of which are incorporated in this document in its entirety as a reference.

This application relates to wireless communication and, more specifically, but without limitation, improved communication pro-activity.

Wireless communication systems are widely deployed to provide a plurality of usersdifferent types of communication (eg, transmission of data, data, multimedia services, etc.). With the rapid growth in demand for high-speed multimedia services, there are problems with the implementation of efficient and reliable communication systems with improved productivity.

To supplement the usual base stations of the mobile telephone network, small baseband stations (for example, installed in the user's home) can be deployed to provide more reliable wireless capability in the premises for mobile devices. Such base stations with a small area of ​​coverage are disclosed. such as access points, base stations, homegroups or femtocells. Of course, such base stations with a small coverage area are connected to the Internet or to the mobile operator's network through a South-East Router or a cable modem.

Since radio frequency (RF) coverage of base stations with a small coverage area may not be optimized by the mobile operator and the deployment of such base stations can be executed according to the principle of abstraction, there may be problems with RF interference. Moreover, for base stations with a small area of ​​coverage may not be supported by a gentle handover. Finally, the mobile station may be authorized to exchange data from the access point, which has the best RF signal, because of the requirements of a limited association (ie, a closed group of subscribers). Thus, there is a need for better wireless interference control.

This document relates to the control of interference by means of hybrid re-use of time. By determining patterns of repeated use of time, creating obstacles, can be configured optimal time reuse of the pathname for the access point. In one of the illustrative embodiments of the invention, the method of communication includes

determining patterns of reuse of the time of adjacent unplanned access points and shuffling the control access point macro. The op-timal pattern of time reuse is chosen based on the maximization of the signal-to-noise ratio of the associated dash-to-dummy terminal.

In another illustrative embodiment, the communications device includes a peripheral controller, made possible to determine the patterns of repeated use of the time of the neighboring unplanned access points, and the signal-to-noise ratio of the access terminals is maximized.

More than that, the aspect may comprise at least one element of the claims.

In some aspects, the principles outlined in this document may be used in networks that provide large-scale coverage (for example, global cellular networks, such as 30 networks, commonly referred to as macro-network networks) and coverage on a smaller scale (e.g. , network environment in an apartment or building). When moving the access terminal (TD) through such a network, the access terminal can be served in certain locations with access nodes (VDs) that provide macro coverage, and in other locations, the access terminal can be served by access nodes that provide a smaller scale. In some respects, institutions with a smaller coverage may be used to provide increased productivity, coverage inside the building and various services (for example, for more reliable maintenance of users). In this paper, the nodes that provide a coat covering relatively large areas may be called macro nodes. Nodes that provide coverage for relatively small areas (for example, in an apartment) can be called fem-nodes. Nodes that provide coverage areas that are smaller than the macro region and more femto-blast, can be called picosecks (for example, which provide coverage in the office space).

A cell associated with a macro node, a fem-node, or a picosecond, may be called a reciprocal, a macro cell, a femtocell, or a pi-colon. In some embodiments, each cell may be further associated with (for example, divided into) one or more sectors.

Various terminologies may be used in different spheres of application to refer to the mother-blood node, femto node, or semicolon. For example, the macro node can be configured as either called an access node, a base station, an access point, an EOBE B, a macro cell, etc. In the same way, the femto node can be configured as, or called, home-based eBoobes, the pre-eNews B, point Access, Base Station, Femtocell, etc.

In some aspects, access points 102, 104, and 106 can be linked to one or more network nodes (for example, a centralized network

controller, such as a network node 114) to facilitate the possibility of joining the global network.

An access point such as an access point 104 may be restricted by the fact that only certain access terminals (e.g., access terminal 110) have access rights to the access point, or other access restrictions may be imposed on the access point. In this case, the restricted access point and / or its associated terms

Access points (e.g., access terminal 110) may interfere with other nodes in system 100, such as, for example, an unbundled access point (e.g., access point macro 102), associated access terminals (e.g., access terminal 108), other restricted access point -turn (e.g., access point 106), or its associated access terminals (e.g., access terminal112). For example, the nearest access point for this access terminal may not be a service point for this access terminal. Accordingly, the transmission of this access terminal may create barriers to access to the access terminal. How. is considered in this document, to reduce interference can be applied repeated use of frequency, choice-by-frequency transmission, removal of interference andIntellectual antenna (for example,

Illustrative operations on system 100 will be described in more detail with reference to FIG. 2. For convenience, the operations shown in FIG. 2 (and any operations discussed in this document) may be described as executable by specific components (for example, system components 100 orcomponents of the system 300 shown in Fig. 3). However, it should be noted that these operations cancomplete components of other types and canexecuted using a different number ofcomponents. Also, it should be noted that one or some of the operations described in this document may not be used in a particular version of implementation.

In the exemplary embodiment, the dot-dupe point 104 communicates with the access terminal 110 via

It should be noted that "in different embodiments between these orother nodes can be used wire-wired or wireless communication lines.

The network node 114, the access point 104, and the access terminal 110 also include various other components that can be used to handle the obstacles disclosed in this accessory. For example, a network node 114, an access point 104, and a terminal 110 may include, respectively, controllers 320, 322, and 324 over-code to suppress interference and provide related functions as disclosed in this document.

2 is shown as a network node 114, access point 104, and access terminal 110 may interact with each other to provide interference control (e.g., easing interference). In some aspects, these operations can be completed on the uplink and / or downlink to reduce interference. In general, you find one or more of the techniques shown in FIG. 2 can be used in separate embodiments described below with reference to FIGS. 7-14. Thus, for greater clarity in the description of individual variants of implementation of these methods may not be described in detail.

As represented by block 202, the network node 114 (for example, the interference controller 320) may necessarily define one or more interference control parameters for the access point 104 and / or access terminal 110. Such parameterscan be presented in a different form. For example, in some embodiments, network node 114 can determine the types of barrier-sensitive information. Examples of such parameters will be described in more detail below with reference in FIGS. 7-14.

In some aspects, when defining the parameters of the obstacles, one can determine how to allocate one or several resources. For example, in the operations indicated in block 402, it can be determined how the allocated resource (for example, frequency spectrum, etc.) can be separated for partial reuse. In addition, when determining the partial reuse parameters, it can be determined which portion of the allocated resource (for example, NLRO repeats) can be used by each access point from the set of access points (for example, restricted access points).

In some aspects, the network node 114 may determine, based on the received information, a parameter indicating whether a barrier of the uplink or downlink may occur and, if so, indicates the level of such interference. Such information can be taken from different nodes in the system (for example, access points and / or access terminals) and in various ways (for example, through a transport network, over a radio channel, etc.).

For example, in some cases, one or more decks of access points (for example, an access point 104) can monitor the ascending and / or descending line and send an indication of the interference detected in the ascending and / or descending line to the network node 114 (for example, periodically or in response to a request). As an example of the first variant, the access point 104 can calculate the signal strength for signals received from neighboring access terminals that are not associated (for example, not served) with an access point 104 (e.g., access terminals 108 and 112), and message alerts this is in the network node 114.

In some cases, each access point in the system can generate a download instruction when

it is subject to a relatively high boot. This instruction may take the form, for example, the employment bit in IhBU-UO, the channel serving for transmitting information about the comparative power of a non-maintenance cell (RSCH) in 3SSR, or some other suitable form. In the standard script, the access point may send this information to its associated access terminal through the downlink. However, such information may also be sent to the network node 114 (for example, via the transport network).

In some cases, one or more access terminals (e.g., an access software terminal) may monitor downlink signals and provide information based on such a track. Access terminal 110 may send the hook information to the access point 104 (which can then redirect the information to the network node 114) or to the network node 114 (via the access point 104). Other access terminals in the system can send information to the network node 114, similarly.

In some cases, the access terminal 110 may generate a measurement message (for example, periodically). In some approaches such measurement message can indicate from which access point the access terminal 110 receives signals, indicating the intensity of the signals associated with signals from each access point (eg, ES / IO), the loss on the route of the extension of any access point, or which Any other suitable information. In some cases, the measurement message may include information that applies to any download instructions received by the downstream access terminal 110.

Then, the network node 114 may use information from one or more measurement messages to determine if the access point 104 and / or access terminal 110 is located close to the other node (e.g., to another access point or access terminal). In addition, the network node 114 may use this information to determine whether the access point 104 and / or access terminal 110 is created for any other node. For example, the network node 114 can determine the intensity of the received signal in some node, based on the transmission power in the node transmitting sig-nali, and the distribution losses on the route between these institutions.

In some cases, the access terminal 110 can generate information indicating the signal / noise ratio (e.g., rain and noise signal ratio, 8YNP) in the downlink. Such information may include, for example, a channel index (SOI), a data transfer rate control indicator (JRC), or any other applicable information. In some cases, this information may be sent to the access point 104, and the access point 104 can forward that information to the intranet node 114 for use in interference control operations. For some approaches, the media node 114 may use such information to determine if there are obstacles in the bottom line.

the lane, or to determine, increase or diminish obstacles in the downstream line.

As described in more detail below, in some cases, interference information can be used to determine how to reduce obstacles. As one example, SDI or other suitable information can be taken for each cycle of the HAR0, with a further determination which of the cycles NARO is associated with the lowestlevel of interference. A similar technique can alsoapply to other methods of partialrexternal use.

It should be noted that the network node 114 can define the parameters by various other methods. For example, in some cases, the network node 114 may select one or more parameters in random order.

As indicated in block 204, the network node 114 (e.g., the communication controller 326) sends defined interference control parameters to the access gate 104. As described below, in some cases, the access point 104 uses these parameters, and in some cases, the access point 104 transmits these parameters to the access terminal 110.

In some cases, the network node 114 may control interference in the system by determining the obstacle control parameters that should be used by two or more universities (e.g., access points and / or access terminals) in the system. For example, in the case of using a partial reuse scheme, the network node 114 may send different (eg, mutually exclusive) parameters for controlling interference in adjacent access points (for example, access points that are close to each other to create interference obstacles) . As a specific example, the network node 114 may allocate the first NARO loop to the access point 104, and the second NARO loop to allocate access point 106. In this case, the communication, carried out by one restricted access point, may not create significant barriers to communication,

As shown in block 206, the access point 104 (e.g., the barrier controller 322) determines the barrier control parameters that it may use or which it can send to the access terminal 110. In cases where the interference control parameters for the access point 104 defines the network node 114, this determination operation may consist in receiving predetermined parameters and / or extracting specified parameters (for example, from data memory).

In some cases, the access point 104 itself identifies the control parameters of the obstacles. These parameters may be similar to those discussed above in the description of block 202. In addition, these parameters may be determined in a method similar to the method discussed above in the compilation box 202. For example, an access point 104 may receive information (e.g., message for measurement, SOI, ORS) from terminal 110 to-dupe. Additionally, the access point 104 may be tracked by an ascending and / or downward line to determine the presence of interference in this line. Point 104

Access can also choose the option randomly.

In some cases, the access point 104 may be operated with other access points to determine the obstacle control parameter. For example, in some cases, the access point 104 can now communicate with the access point 106 for determining which parameters are used by the access point 106 (and choose other parameters), or to coordinate the use of different (eg, mutually exclusive) parameters. In some cases, the access point 104 can determine if it will create interference to another node (for example, based on the SOI feedback that indicates that the resource uses another node) and, if so, define its own forwarding control parameters in such a way as to minimize any possible disruptions.

As shown in block 208, the access point 104 (e.g., the communication controller 328) may send interference control parameters or other relevant information to the access terminal 110. In some cases, this information may relate to the power management (for example, to determine the transmission capacity of the uplink).

As shown in blocks 210 and 212, the dot-to-dither point 104 may execute the transmission to the downlink access terminal 110, and the access terminal 110 can execute the transmission to the access point access point 104 of the uplink. Thus, the access point 104 may use its control parameters for the downlink transmission and / or for uplink reception. Similarly, the access terminal 110 may take these parameters into account when interfering with reception in a downlink or uplink transmission.

In some embodiments, the access terminal 110 (e.g., the barrier controller 306) may determine one or more interference control parameters. Such parameters may be used by the access terminal 110 and / or may be sent (for example, by a communications controller 330) to an access point 104 (e.g., for use in uplink operations).

4 is a wireless communication system 400 provided with the ability to support a dozen users, in which the principles outlined in this document may be implemented. System400 provides communication for a plurality of honeycombs 402 such as, for example, 402A-402C macrocells, with each cell being served by the appropriate access node 404 (e.g., 404A-404C access universities). As shown in FIG. 4, access terminals 406 (e.g., to-dupe terminals 406A-406B) can be dispersed in different locations throughout the system over time. Each access terminal 406 can currently communicate with one or more downlink (OB) access nodes404 (also called the direct line (RB)) and / or the uplink (BIB) (also called the backward line (RB) ), depending on, for example, whether the access terminal 406 is active, and whether it is in a soft swap state. The wireless communication system 400 can secure the broad geographic service

the area. For example, macroblocks 402А-4020 can cover several neighboring neighborhoods.

As already mentioned, the nodes or local access points that provide coverage in a relatively small area (for example, in an apartment) can be called femto nodes.

5A illustrates an illustrative system of 500 communications in which, within the network environment, one or more femto nodes are dispersed. In particular, the system topic 500 includes a plurality of femto nodes510 (for example, femto nodes 510A and 510B), which are located in a networked environment relatively small in scale (for example, in one or more apartments of 530 users). Each femto node 510 can be connected to a global network 530 (eg, the Internet) and a base network of 550 mobile operators via a U.S. router, a cable modem, a wireless line, or other connection means (not shown). As discussed below, each femto node 510 can be executed with the ability to service the associated access terminals 520 (e.g., access terminal 520A) and, optionally, unassociated (foreign) access terminals 520 (e.g. Terminal 520P access). In other words, access to the subnet 510 may be limited, whereby this access terminal 520 may be served by a set of designated home fetch nodes 510, but may not be served by unsigned femto nodes 510 (for example, a neighbor femto node 510).

FIG. 5B shows in more detail the negative geometry for a plurality of femto nodes and access terminals in a network environment. In particular, the femto node 510A and the femto node 510B, respectively, are dispersed in the neighboring apartments of users 530A and 530B. Access terminals 520A-520S are allowed to associate and communicate with the femto node 510A, but not with the femto node 510V. Similarly, the 520U terminal and access terminal 520E are allowed to associate and communicate with the femto node 510B, but not with the femto node 510A. Terminal 520E and access terminal 5200 are not allowed to associate and communicate with either the femto recovery scrap 510B or the femto node 510A. Terminal 520E and the access terminal 5200 may be associated and communicate with the access node 560 of the macro-cell (FIG. 5A) or another femto node in the other apartment (not shown).

In the arbitrary deployment of femto nodes 510 with limited association (ie, the access point may not be allowed to associate with the nearest femto node, which provides the best quality signal), common are interference and negative geometry. Solving the problem of negative geometry are discussed below.

6 illustrates an example of a coverage map 600, which identifies several areas of 602 tracking (or routing areas, or areas of routing), each of which includes several areas of 604 macro coverage. In this case, the coatings associated with the tracking areas 602A, 602B and 602C are marked by wide lines, and the area of ​​the 604 macro coatings are represented by hexagons. The 602 tracking areas also include areas

606. In this example, each of the 606 fem-top coverage areas 606 (e.g., the femtocoupling area 606C) is depicted within the area of ​​macroblock area 604 (e.g., macro-coverage area 604B). It should be noted that the femtocouple area 606 may not be inside area 604 macro coverage. In practice, this area of ​​602 tracking or the area of ​​604 macro coatings can be defined with a large number of areas 606femt coating. In addition, one or more pico-pictorial areas may be defined within the area 602 of the field or 604 macroscopic area (not shown).

As shown in FIGS. 5A, 5B, the femto network 510 may subscribe to a mobile service, for example, a mobile service 30 provided via the mobile carrier's base network 550. In addition, the access terminal 520 maybe designed to work both in a macro-network environment and in a network environment of a smaller scale (for example, the scale of the apartment). In other words, depending on the current status of the access terminal 520, the access terminal 520 can be served by a 560 access node 550 of mobile communication with macrocells or one of a plurality of femto nodes 510 (for example, femto nodes 510A and 510B which are located in the corresponding user room 530 ) For example, when a subscriber is outside his home, he is served by the usual node of the macrodost-pu (for example, the node 560), and when the subscriber is at home, It is served by a femto node (for example, a 510A node). It should be noted that the femto node 520 may have back-up compatibility with existing access terminals 520.

The femto node 510 can be deployed at one frequency or, alternatively, at the time-frequency plural. Depending on the specific configuration, one frequency or one or more of a plurality of frequencies can overlap with one or more frequencies used by the macro node (for example, node 560).

In some embodiments, the access terminal 520 may be configured to communicate with the preferred femto node (e.g., the home femto node of the associated access terminal 520), if such a connection is possible. For example, if the access terminal 520 is within the user space 530, it may be justifiable for the access terminal 520 to communicate only with the home femto node 510.

In some embodiments, if the access terminal 520 operates within the 550 network with pop-ups, but is not located on its most preferred network (e.g., as the list of preferred roaming lists), the 520 end-to-end terminal can continue to search for the most preferred network (for example, a home femto node 510), using the repeated selection of a better system (VZR), which may include periodic scanning of available systems to determine if the best systems are currently up-to-date, followed by associative with such preferred systems When searching, the terminal is 520

17

97033

18

access may restrict the search for a specific bandwidth or channel. For example, the search for the most advantageous system can be repeated from time to time. After detecting the preferred femto node 510, the access terminal 520 selects the femto node 510 for permanent connection within its area coverage.

In some embodiments, the femto node may be subject to restrictions. For example, this femto node can only provide certain services only to certain access terminals. When deploying a so-called limited (or closed) association, this access terminal can only be serviced by a mobile network with pop-ups and a specific set of femto nodes (for example, femto nodes 510 that are located within the respective user's apartment 530). In some embodiments, the node may be enclosed in such a way that it does not provide at least one node of at least one of the following: signaling, data access, registration, call, or service.

In some embodiments, a limited or a femto node (which may also be called the homepage of a closed group of subscribers) ensures the services of a limited set of terminals of dos-dupe. This set can be expanded temporarily or on a permanent basis. In some embodiments, a closed group of subscribers (CIOS) can be defined as a set of access nodes (for example, femto nodes) that share a common access control terminal access list. A channel on which all femto nodes (or all the finite femto nodes) work in this area can be called a femto channel.

Between the given femto node and the given access terminal there may be different attitudes. For example, from the point of view of the access terminal, the open femto node can be considered as a femto node without a restriction on association. Limited femto nodes may be femto nodes, on which certain restrictions (for example, restrictions on association and / or registration) are imposed. A home-made femto node may be a femto node, for which the access terminal is authorized to access and work. Guest femtovuzol may be a femto node, for which any access terminal is temporarily authorized to perform access and work. A limited or a small femto node may be a femto-zol, with respect to which the access terminal is not authorized for access and operation; Except for possible emergency situations (for example, call 911).

From the point of view of a limited or alien femto-evil, an associated or home access terminal may be an access terminal, which is automated to access the restricted femto node. Guest access terminal can be a temporary access terminal with a limited femto node. A non-associate (alien) access terminal may be an access library that does not have permission to receive access to a restricted femto node, for

Except, perhaps, emergencies such as

as a 911 call (for example, an access terminal that is

has no authority or permission to register in

limited femto node).

For simplicity, this document describes various functions in the context of the femto node. However, it is necessary to note that picoseconds can provide similar or similar functions for a larger area coverage. For example, pikovazol may be restricted, home picozool can be determined for this access terminal, and so on.

A multiple-access wireless system can simultaneously maintain communication for a plurality of wireless access terminals. As indicated above, each terminal can communicate with one or more base stations with the help of downlink (straight line) and uplink (backward) gears. The downlink is a communication link from the base stations to the the-terminals, and the uplink represents a link from the terminals to the base stations. This communication line can be installed using the system with one input and one output, the system with. multiple inputs and multiple outputs (MIMO) or systems of another type.

The MIMO system uses a plurality of transmitters (Ντ) for transmitting antennas and a plurality (Νκ) receiving antennas for transmitting. The MIMO channel formed by the NT transmit antennas and the NK receiving antennas can be decomposed into N3 independent channels, also called the prophylactic channels, where N3 <ιτιίπ {Nτ, Nκ}. Each of the N3 independent channels corresponds to the dimension. The MIMO system can provide increased pro-activity (for example, higher throughput and / or increased reliability) if additional dimensions are used that is created by the total number of transmitting and receiving antennas.

The MIMO system can support duplex communication with time division (TUI) and duplexconnection with frequency division (TG). In the system, the transmission in the forward and backward lines is performed in one frequency region, so that the principle of co-ordination makes it possible to estimate the channel of the downlink (straight line) from the channel of the ascending line (the return line). This allows the access point to determine the gain in transmission with the formation of the beam on the downstream line, if multiple antennas are available at the access point.

As already indicated, with arbitrary expansion of base stations with constraint on the association of baths (that is, the mobile station is not allowed to associate with the nearest base station, with which it can establish the most reliable connection), common are interference and negative geometry. In one illustrative embodiment, the spatial structure of which is depicted in FIG. 5B, the femto node 510a and femto node 510 are deployed in adjacent apartments. Terminals dos-dupe 520A-520S are allowed to associate and communicate with the 510A femto node, but not with the femto node 510V. Similarly, the access terminals 5201E-520E allow association and connection with the femto node 510B, but not with the femto node 510A. Terminals of access520G-520C are not allowed to associate and communicate with either

19th

97033

20

one of the femto nodes 510A-510V. The dummy terminals 520P-520C can be associated with a macrocell accessory node 560 (FIG. 5A) or with another fem-node in another apartment (not shown). Consequently, such a negative geometry relative to the femto facilities, allowing access, and adjacent access terminals can lead to interference and noise in the ascending and descending lines.

DEVELOPMENT OF THE LEADING LINE

For an example, assume that i_az (6B) and i_a5 (6B) represent the loss on the route of the distributionfrom the femto node 510A, the terminal 520S access andterminal 520U access, respectively. In particular, and_ can be much more than and_5. Thus, as the access terminal 520 performs the transmission to the home femto node 510B, it creates over-interference (or drowns) the femto node 510A, effectively blocking the reception of the access terminals 520A-C in the femto node 510A. In such a situation, the downlink of the uplink, even if the 520 Access terminal communicates with a maximum Th output power, adopted by C / I for the access terminal in the fem node 510A can be characterized by the following way:

C / I (AT 520C in femto node 510A) =

= Pzta-I-AZ- (P5-I-A5) (6B).

In some illustrative embodiments, depending on the power of the P5 transmission, the C / I terminal of the 520C access point in the femto node 510A may be very large negative number because of the large value of the i_az. Such a geometric configuration is calledvery negative geometry of the ascending line.

DEVELOPMENT OF THE NICE LINE

Similarly, in one of the illustrative embodiments, I_v5 can significantly exceed I_A5. This means that when the femto node 510A transmits an access terminal 520A, it may create overly strong interruptions (or drowns) in the Terminal 520U access, effectively blocking receiving a 520b femto node in the access terminal 520. In such a situation, the downlink downhill, adopted by C / I for the femto node 510B in the access terminal 5200, can be characterized as follows:

C / I (femtoceller B in AT 5) =

= Rv-i-u₅- (ra-and-ah₅) (6B).

C / I femto node 510B in the access terminal 520Can be a very large negative number because of the small value of I_B5. Such a geometric configuration is called a very negative geometry of the bottom-line line.

The practical options discussed below allow you to solve the problem of negative geometry without the need to modify the work of already existing access terminals. Thus, in this illustrative embodiment, it is desirable to provide a reduction of the obstacles arising from the negative geometry, by modifying the processes in the femto node, and not at the access terminals. Accordingly, the problem of the uplink and downlink negative geometry is solved by means of an illustrative embodiment described below.

With reference to FIG. 7, as well as to FIGS. 5A, 5B, operations relating to beam positioning and polarization control will be described in detail.

minimize the orientation diagram for the ro-connection of the problem associated with muffling and negative geometry. This illustrative embodiment employs methods and hardware to prevent silhouetting and negative-geometry-related effects by utilizing the positioning of the beam and controlling the position of the minimum directivity pattern in the arbitrary location of the base station by restricted access.

In the illustrative scenario of the deployment of the fem-knot, the neighboring signals (necessary or obstacles) can be fair in nature, which means a strong directional component and uniform fading in the frequency band (due to small dispersal of delays and traces with multiple reflections inside the building). Especially in the case of silencing, partitioning into sectors can ensure the desired method of counteracting a strong racial component of the obstacle.

As shown in block 702, the femto node 702 listens continuously (i.e., receives according to various receiver configurations described in this document) in order to detect non-paging from access terminals 520. As shown in the branch section 704, the femto node 510 determines whether an access attempt is attempted (for example, transmission) performed by the access terminal, femto node 510. If an access access attempt is detected to a specific femto node 510, then, as shown in block 706, there is no need to reduce interference, since the access terminal with an access terminal associated with the home femto node.

As shown in Branch Block 708, femto-Tovuzole 510 then compares the characteristics (e.g., power level) of an attempt to obtain access to a determination, or exceeds the threshold threshold characteristic, which results in the impediment to the home femto node. If the attempt to receive access does not exceed the threshold of impedance, then, as shown in block 706, there is no need to reduce interference, since the characterization of an attempt to access access by the home femto node 510 leads to acceptable reimbursements.

As shown in block 710, if the home femtovuzole 510 takes a sufficiently strong signal (for example, exceeding the threshold of interference) of an access test signal or any other uplink signal from an unassociated access terminal 520, the home femto node 510 uses antennas that form the beam (tob- then, directed transmission and reception), for orientation of the direction of signals or absence of signals (for example, zero diagram) in the direction of the unassociated access terminal 520 in the downlink and ascending line.

For example, beamforming (i.e. beam direction control) can be accomplished by using a sectorized or directed (e.g., beam switching) configuration of the antenna described in this paper for beamforming and / or the minimum of a transmission signal orbeam and / or a minimum receive signal . In particular, resetting barriers can be performed for ra-

21

97033

22

The received RF signal (RF) signal changes, thus, the problems in the receiver, such as overloading the input stages and reducing the sensitivity of the analog-digital transformation, which is the consequence of femto node muffling. In addition, the securitization or directional configuration of the antennas allows storage for, ascending and descending lines of the same directional component, to be used in both directions of transmission.

As shown in block 712, the transmission of service signals and pilot signals in the downlink, as well as transmissions over the traffic channel, if any, are executed in accordance with the formation of the beam, in such a way that a minimum amount of energy is sent to the neighboring non-associated terminal. Direction of the transmission signal to the side of the non-associated access terminal leads to reduce the effects of negative geometry for an unassociated access terminal.

As shown in block 714, the minimum chart orientation is oriented towards the nearest unassociated access terminal 520 using an antenna configuration (for example, sector-oriented antennas, or by controlling the minimum direction of divergence by means of an adaptive phase antenna array) described in this subsection. Thus, when the associated access terminal 520 attempts to contact the home femto node 510, the access attempt attempt signal associated with the access terminal, as well as another traffic (e.g., voice / data), will not be suppressed by strong signaling from neighboring unassociated access terminals having non-negative geometry.

For example, if the access point uses two separate antennas, the access point can follow the characteristics of the signals of the attempt to obtain access from the access terminal on both antennas. When one antenna detects a strong signal transmissions on the uplink from an unassociated access terminal, the access point can disable the transfer function (beam direction control) and disable the receiving function (directing the minimum chart) on this antenna.

As shown in the branch block 716, femto-sol 510 periodically (for example, once per second) excludes the sectorization of the minimum chart in the on-line reception to determine how the block 702 is represented, or whether the unassociated access terminal 520 with a strong signal is moved or stopped transmitting. If, as shown in block 704, the strong unwanted signal disappears, the femto node 510 may rule out the sectorization of the minimum of the diagraph and continue with the omnidirectional transmission and reception, as shown in block 706. Anyhow, a strong unwanted signal is still present moved and exceeds the threshold value, as shown in block 708, the femto node 510 may improve the sectorization of receiving and transmitting the direction of orientation of the zero of the direction diagram as shown in block 710 in the direction of the non-associated unassociated access terminal 520.

In the example described above, with reference to FIG. 5B, the k-frame shows a femto node 510A that directs the null digraphs during sectorization in the non-associative-

the access terminal 520U while not connected to the 520U access terminal is in the state of the active connection to the femto node 510B. When the non-associated 520U access terminal is in the standby mode, the femto node 510A is returned to work with omnidirectional transmission and reception.

During the periods of zero orientation of sectorization in a particular direction, if an associated access terminal 520 is displayed in this direction, it may be interrupted at work. Accordingly, in the illustrative embodiment, the femto node 510 directs the zero of the sectorization (i) only the unwanted unassociated access terminal 520 with the strong signal is active, and (ii) only if the unauthorized transmission from the unassociated access terminal 520 exceeds the high power threshold of the signal in the receiver, as determined in the blocking unit 708 indicating on the fact that the attempt to receive access from the desired associated ter minals of access can not be decoded in the fem node 510. Referring to FIG. 5B, it should be noted that the femto node 510B may not orient the zero of sectorization in the direction of the non-azocated access terminal 520A, because the signal from the non-associated terminal 520A access is not very strong. If the femto node 510B focuses on the sectorization in the direction of the unconsolidated access terminal 520A, this will lead to a break in the work of the desired associate access terminal 520.

In general, if the access point can not determine the direction of interference from the non-associated access terminal (for example, in the case of very strong muffling, which leads to the saturation of the access point receiver), it may 'try to use different directions to orient the radius and the zero diagram to maximize the quality of the received signal from an associated ter-minal of access.

With reference to FIG. 8, as well as FIGS. 5A, 5B, a detailed description of the operations related to the use of power optimization of transmission through service channels to solve problems related to muffling and negative geometry will be provided. . This illustrative embodiment uses methods and hardware for preventing silencing and effects associated with negative geometry, using the motivated levels of power in service channels at arbitrary deployment of base stations.

In general, the power level of the pda-editions on the service channels and the total power of the femto node transmissions are determined, based on the desired range of femto node operation. To enable the access terminals, obtain access to the femto node in the location where the access terminal is drowned by the neighboring fetch node that refuses to associate the service channels (e.g., common control channels such as pilot channel, synchronization channel, and multichannel transmission / call channel). ) can be sub-data for time multiplexing. To do this, various time scales and timetime multiplexing may be used. In addition, the service

23

97033

24

the channels can only be switched on from time to time, for example, by the cyclic index of the associated access terminal slots, so that the associated access terminals can receive a callback. In another configuration, the femto node can not generally perform signal transmissions.

However, during an active voice call or data transmission, there may be no waiting periods that provide the neighboring fem node the possibility of time multiplexing service channels, muted due to the presence of a negative geometry. Accordingly, an illustrative embodiment of the invention describes a method for optimizing the power of transmission of service signals (for example, pilot channels, synchronization channels and broadcast broadcasts / calls channels) in the presence of an active call in the femto node, when the time multiplexing of service signals is not practical.

For example, in ICRT and XVI networks, levels for service channels (for example, pilot channels, call channels, synchronization channels) are tuned for specific performance based on geometry and buzz constraints. In addition, the deployment of femto nodes is significant from minima in comparison with the deployment of access nodes with macrocells. Such differences include:

1. Due to the limited size of the coverage, the maximal value of losses on the route is much lower for oblasts (for example, stalnikov), served by femto nodes, incompared with areas (for example, cells) served by access nodes with macrostates (for example, 80dB of maximum losses in size distribution compared with 140dB in the version deployment with macrocells).

2. The number of simultaneously active terminals upstream is less in the cells served by the femtom nodes than in the cells served by access nodes with macrocells (1-2 users-vouchy compared with 20-40 users).

3. As discussed above, as a result of restrictions on the association with femto nodes, the negative geometry of placement may be a common occurrence in the deployment of femto nodes, in contrast to the deployment of access nodes with macrocells.

These differences can lead to optimal power settings that are very different for service channels for femto knots 510. Since the femto node 510 usually has from zero to several active terminals 520, it would be desirable to maintain service channels at the minimum power level to reduce non-interference with the neighboring the cells served by the femto nodes 510 and the access nodes 560 with the macro-cells (that is, it is assumed that the robots have common roots). For example, in one illustrative embodiment, the emphasis is on optimizing the pilot channel, the analysis is also applicable to other service channels.

In the illustrative embodiment, the optimal value of traffic-to-pilot (T2P) is determined for a case where a single voice call is defined, as well as power-

By default, the Pilot Ethernet · When the downlink power control (forward line) changes the traffic-to-pilot ratio, the pilot power tuning is adjusted so that it maintains the lowest total transmission power and interference caused by the neighboring femto node

For example, the access terminal 520A at the edge of the home femto node 510A and the neighboring femto node 510B have the same losses on the distribution path for both femto nodes 510, and the neighboring femto node 510 performs transmission at full power, thereby creating interference, Iog_takam.U In this example, assuming that the home femto node transmits a pilot-channel with some level power, ESR, the pilot-to-noise ratio (3NP) can be written down as follows: ESR / yog_tah. In accordance with this illustration, one needs to find the optimal ESR installation, which will result in the smallest total transmit power from the home 520A fem-node.

As shown in block 802, the level of ESR amplification in the pilot channel is initialized by the value of the EeroErdyt · Thus, the default Ehrr (EzroEgypt) can be determined based on the most significant differential loading and propagation loss rates expected on the networks.

As shown in block 804, a traffic call (for example, a voice call) is set between the home-based femto node 510A and a power-up terminal 520A with the power used in the channel trace marked as ESC. In one of the illustrative embodiments, the value of UE is determined by controlling the downlink power (straight line) as shown in branch 806. The downlink power control (direct line) is used to maintain the required quality of service (for example, the required packet error level, RPM). The power control of the downlink (line) can either indicate a decrease in the ECI as shown in block 808 or to increase the ECI as shown in block 810 or indicate the absence of changes in the ESC

As shown in block 812, packet-level error detection (RPM) is used to identify an adequate signal quality. In the general case, if ESR is very low, then the quality of the channel will deteriorate, which will lead to a very large ESI. With the increase, the quality of the channel will improve, and the need for the EIA will decrease. However, if ESR becomes very large, then the quality of the channel will exceed the required value, which will not lead to a further reduction of ESG. Accordingly, if RER is inadequate, the power control of the downlink (straight line) adjusts the ESG

Since the interference generated for other femto nodes must be minimized, it is necessary to obtain the optimal value of ESr, which leads to a minimum (ESI + ESR). As shown in block 814, is determined by Esorortdi, where:

Esortimdi_ = Agd [Esr + t (Epo)]

ESR

26

In other words, they find the optimal value of ESR, which minimizes the overall power of the transfer, where

ESI-G (ESR)

(the function t (.) can be determined by the help of autonomous modeling or tests).

Then, as shown in block 816, the optimal ECI value is defined as:

T2RorthamaI_

ExcerptAg ^ Esorortdi).

As shown in block 818, T2RorthamaI is defined as:

_ ^Es* ORTIMA_

In another illustrative embodiment, the simulation can be performed for the purpose of identifying Esorthima and EsIorthima. For ordinary types of channels expected in cells of femto nodes, for example, using models with even or Relay or Ryan fading, a lower Doppler effect, which can be detected by means of power control . In the illustrative embodiment, these optimal values ​​depend on the differential value of specific losses on the extension path from the access terminal to the neighboring femto node and from the power of the interference received from the neighboring femto node (for example, if the mobile terminal has losses on the route the distribution of adjacent femto node is 3 dB less compared with the home femto node, then the optimal values ​​of Ers and ESI should be increased by 3 dB).

On the other hand, in an alternative illustrative embodiment, if an adjacent femto-owl transmits at half the yoggpah, then the optimal values ​​of ESR and ESI should be reduced by 3dB. Nevertheless, it should be noted that it is not practicable a very frequent change in the value of Ers, since it indicates the femtocell redirection boundary. Thus, as already mentioned, the value of ESR as the default setting (ErroBRAyte) can be determined based on reasonable differential load values ​​and losses on the propagation path expected by the femtom networks.

As shown in FIG. 9, in order to maintain an optimal mode of operation in cases with differential load values ​​and traffic losses exceeding the expected values, in one illustrative embodiment, the following algorithm for each of the the set of calls occurring between the femto node and the set of associated term access points.

As shown in block 902, the level of ESR amplification in the pilot channel initializes the value of the ErrorThis DNalysis of each voice call. Thus, the value of the ESR by default (ESROBBA) can be determined, based on reasonable diffeential values ​​of loading and losses in the extent of propagation expected in the feminine networks.

As shown in block 904, the process is repeated for each call established between home FT-node 510A and associated access terminals 520 with the power used in the traffic channel marked EII. In one illus

In a truant embodiment, the values ​​of the ECI are determined by power control of the downlink (straight line), as shown in the branch block906. Control of the power of the downlink (straight line) is used to maintain the required quality of service (for example, the level of bug errors, rEv). The control of the downlink power (straight line) can either be indicated by decreasing the ECI, as shown in block 908, or indicating an increase in ESI, as shown in block 910, or indicating no change in ESI.

As shown in block 912, packet-bounce rate detection (REA) is used to identify the adequate signal quality. Accordingly, if the REA is inadequate, the control of the power of the downlink (straight line) adjusts the ESI.

As shown in block 918, T2RibiTeave (for example, Ethernet / Ethernet) is monitored during a call. The purpose of T2R filtering is to eliminate small scale fluctuations in the calculation of T2R. For example, a moving average filter can be used to filter the values ​​of ESI and ESR for the calculation of ESIputevEO and ESBRIBITIVE, respectively.

As shown in branch 920, perform an analysis of the value T2Rriteveo. If

Τ2Ρπι_τεβεο> Τ2Ρορτιμαι_⁺Δι then, as shown in block 922, Επr are increased to:

T2RorthamaI depends on the specific configuration of the traffic (speed, coding, etc.). For example, if two users perform voice calls, using vocoders with the same speed, they will have the same value T2Rootmati_. However, if another user who is transmitting data is present (for example, IWFT data transfer at 153kb / s), this requires another T2Rootmati_. After determining T2RorthamaI For a given user (based on its type of traffic), the algorithm automatically adjusts ESR. Such algorithm is defined for one user. In the case of a plurality of users, the algorithm may give different values ​​of Ers for each user. However, service channels are common to all users, and we can only have one installation for ESR. Thus, the algorithm can be generalized to the case of a plurality of users. Example, "

for users from 1 to N in a femtoceller. The purpose of the T2P filtering is to eliminate small scale fluctuations when computing T2P. For example, a moving average filter can be used to filter the values ​​of ESC and ESR to calculate ESI and ECCEL, respectively.

The optimal T2P can be obtained by the help of simulation, and after determination of T2, it is possible to determine the adjustment of the ESC (which is part of the operation of 3C standard) with the help of power control. Then ESR tune to achieve / maintain T2P. In particular, two algorithmic rhythms can be performed jointly: 1) the algorithm of the power adjusting the ESC; 2) Essex sub-roving, described in this document.

In the above algorithm, Δί and Δ2 are the parameters of hysteresis, used forprevention of rapid fluctuations ESR. In addition, in order to prevent abrupt changes in the ESR, the above-mentioned enhancements can be modified, in a single illustrative embodiment, in order to perform the correction of ESR more slowly. Other service channels (for example, call channel, synchronization channel) can be tuned based on the pilot level of the pilot (that is, their relative power level can be maintained constant with respect to the pilot power level).

Thus, illustrative embodiments have been described for reducing the transmission power of service signals (for example, pilot channel, synchronization channel, and broadcast / call channel), in the presence of an active call femto node, by determining the optimal grid -the power of service signals. Illustrative version of the implementation was described using a pilot-channel as an illustrative channel. However, this analysis can also be applied to any service channel.

Below, with reference to FIGS. 10 and 5A, 5B, operations relating to the use of a frequency selective transmission for solving problems associated with muffling and negative geometry are described in more detail. As noted, due to the de-free deployment of femto nodes, adopted 3YNP for an associated access terminal maybe very low due to the obstacles arising during the transmission performed by the neighboring femtovz-scrap. Such interference impairs the efficiency of the control channel and the traffic channel of the access terminal, and as a result may lead to a break in work or to reduce the number of services. The illustrative implementation options disclosed in this document are aimed at improving the productivity of the ter-minal of access in the area with strong obstacles without the need to replace the existing terminals access.

In the general case, in the illustrative embodiment, the specially selected frequency selectivity for transmission in the downlink line is transmitted to the impedance of the signal form in the transmission of relative neighboring femto nodes to minimize the interference. As an example, each femto node 510 selects a fo-

rm pulse transmission by reading the channel from available signal forms, for example, from the threeforms of the 3-channel channels, with each set of coefficients from the given line, for example, 3 * 3 of the matrix. In this case, for this access point, each form of the transmitted signal will be off-filter 3-1ar PIP (in addition to the normal filtering of the main band) with impulse filter cues selected from one of the following three forms of signals:

ηι [η] = δ [η-2] + δ [η-4]

.2π .2π

I2 [η] = δ [η] + Θ ³ δ [η-2] + θ ³ δ [η-4] =

= δ [η] + (- 0,5 + t 0,866) · δ [η-2] + (- 0,5 + t 0,866) · δ [η-4],

.2π .2π

I3 [η] = δ [η] + Θ ³ δ [η-2] + θ ³ δ [η-4] =

= δ [η] + (-0.5 + ί0.866) · δ [η-2] + (-0.5 + ί0.866) · δ [η-4], where Exp (X) = c05 (x) +] 5IP (x)

An alternative choice is two impulsive reviews with coefficients of 2 * 2 IRT (N = 2). The selection of the transfer filter is stored for some time, after which the femto node 510 can perform a re-selection based on the channel read-out.

With reference to FIG. 10, the method of controlling interference is described in the selection of the signal form of the transmission in a wireless communication system. As represented in block 1002, a set of N waveforms is assigned to the femto node 510 for use in downlink transmissions. In one illustrative embodiment, the channel signal form may be formed from the coefficients of the N-Iar channel filter with each set of coefficients obtained from a particular line in the N * NYTT matrix.

As shown in block 1004, the femto node 510 performs the choice of the default signal form during initialization (e.g., sinking) according to the determined selection process (e.g. random assignment by the network, etc.). Forms signal by default are selected from the set Nforms of transmission (downlink). The default signal format is initially set to be a non-destructive transmission signal, T * ZaouerEREREo.

As shown in block 1004, when the cell is initiated, the femto node 510 transmits the downlink using a preferred form of the transmission signal. A call is connected to an associated access terminal 520, which includes indicators for channel quality (e.g., channel quality indicator (ΟΟΙ), speed control data (UE)) determined by the access terminal 520 and sent directly to the femto node 510 on the uplink.

As shown in block 1008, the femto node initiates a test signal cycle for the time period T_Ie5I_majyogt until all possible signal forms are tested. As shown in block 2010, the femto node 510 communicates with an associated access terminal 520 using a current signal form. Associated Terminal Access accepts downlink transmission and generates a channel quality indication in response to the quality signal. The channel quality indication is directed to the uplink (return line) to the femto node 510.

As shown in block 1012, the femto node identifies an ascending line for determining the channel quality using the current signal form based on the received channel quality indication. Femto node 510 can either form a tableforms of signals and corresponding quality indicators of a canal, or compare the current indicator of the quality of the channel with any previous indicators of the quality of the channel and the stored indicator of the preferred form of the signal.

As shown in block 1014, the signalformation test passes to the next intended signal for continuous evaluation. Illustrative process of selecting the shape of the signal repeatsdate, as long as the possible forms of the signal will not be received until the downlink transmission, and the indication of the quality of the corresponding channel on the east-line is not taken. As shown in block 1016, the preferred signal form is based on determining the quality of the channel, then selected as the preferred form of the transmission signal, which provides the best quality of the channel in the presence^t obstacles due to the negative geometry associated with the deployment of other base stations with arbitrary placement.

As shown in block 1018, the preferred signal format may be periodically updated, based on various factors including specific periods of time, call termination, threshold quality degradation of the channel, or other state of the channel known to those skilled in the art. After the update is determined, the processing returns to the evaluation of the channel quality of the various possible forms of transmission.

In this illustrative embodiment, the control of interference arising from the high energy of adjacent interference is carried out in the result of the orthogonality of the Fourier series on the predominant signal energy during convolution, the cost of creating its own noise through the IRI, and thus the interfacing of the performance with a good geometry. An additional gain could be obtained using the MIMO equalizer due to the different time-coloring of impulse feedback for the desired signals and interference signals. Such a mechanism is real in the configuration of the femto node, since the spacing of the delay is significantly less than the interval of one elementary signal.

With reference to FIGS. 11A-11B and FIGS. 5A, 5B, an operation describing the operation of adjusting the noise factor and adjusting the loss on the propagation path to solve the problems associated with muffling and negative -ometry This illustrative embodiment uses methods and devices for preventing silencing and for solving problems associated with silencing and negative geometry, using an adaptive adjustment of the noise factor and losses on the propagation path.

Of course, femto nodes are connected to the Internet540 and the reference network of 550 mobile operators through a broadband connection (for example, mar-shuritizer UZI_ or cable modem). Since the RF coverage of the femto nodes 510 is not optimized by the mobile reference network 550 of the mobile operator and the deployment is usually performed according to the principle

If there is a problem, there may be serious problems

we are dealing with RF impediments, if not used

code.

In networks with macro-terminals, access terminals 520 and 560 access nodes to macros are developed with the ability to work in a defined dynamic area. In the cells formed by the fem-knobs 510, the home femto node 510 and the associate access terminal 520 may have an accidental spatial location relative to the neighbors, thus creating very high levels of signals beyond the sensitivity range of the respective receivers. On the downstream line (straight line), such a configuration can introduce saturation of the receiver associated, access terminal and impair the performance of demodulation. On the reverse side, such a configuration can create a very strong noise overriding (RoT), which is known to create instability in the home femto node 510. Thus,

Femto nodes 510B can cause noise as in the uplink line ii (in the back line), and in the downlink line UI_ (straight line) of the cell served by the macro access node 560. For example, the femto node 510B, such as, for example, the 530 apartment bedside can cause significant overhead codes in the downlink line UI_ in the access terminal 520P, located outside the home (that is, non-associated access terminal), which is not served by the 510B femto node. Also, the uplink and the associated access terminal 520, which is served by a specific home femto node 510, can cause significant interference in the macro cell access nodes 560.

On the uplink, the unpowered 520P access terminals that are served by the macrosatellite access nodes 560 can cause significant interference in the home femto node 510A.

As it was noted; femto nodes 510 can also create significant obstacles in relation to one-one as a result of arbitrary placement. For example, in a neighboring apartment 530 femto node 510, installed at the wall separating two flats 530, can cause significant obstacles relative to the neighboring femto node 510 in the adjacent apartment 530. In this case, there may be no need for the strongest signal ( in terms of the RF signal) from the femto node 510 to the access terminal 520 concerned the home femto node associated with the access terminal due to the association restrictions described above. Such a scenario is shown in FIG. 5B, wherein on the downstream line of the UI femto node 510A may cause significant interference (e.g., low 3 / IR) in the access terminal 520. Also,

For example, in the ascending line of the wireless network of SUMM, the stability and loading of the system are naturally determined by the following parameter: ne-excess over thermal noise (RH), also known as noise over-noise in the femto node. Rising over thermal noise (RH) indicates the relation between total power adopted by all sources in the femto node, and thermal shu-mum:

PtoT = (Ιοο + Ιογ + Νο) / Νο,

where

Yog: the total received power received in the femto node of all wireless devices, for which this femto node is in their active collection,

Ios: the total received power received in the femto node of all wireless devices, for which this femto node is not in their active collection,

Nо: dispersion of thermal noise, which includes noise coefficient (NE) femto node.

For stable operation of the system on the ascending line, i__ requires control over the RH. Of course, ensure that the RH is about 5dB or higher. The values ​​of Root can lead to significant degradation of productivity. For example, in FIG. 5, for two neighboring cells formed by femto-loops 510A and 510B, high RT caused by 520U access terminal femto node 510A results in degradation of the associated terminal 520C access. There is one specific jumper scenario when the neighboring 520U access terminal has pulsating uplink traffic and shows very high power levels (for example, very close) in the femto node 510A. Consequently, during the transmission of a packet of pulses transmitted at high speed on the uplink line and from the 520U access terminal, the rotor in the femto-evil 510A gives 20dB. More, The control mechanism of the power in the ascending line and in the Siemens systems (for example, SUMMA2000, MSYUM, ΙχΕν-ΥΟ) is designed to combat such a type of interference-emergence scenario. However, due to the very high-dispersion in the RT, this mechanism can take some time, it is necessary femto node 510A to overcome the obstacles in the associated terminus dos-dupe caused by the unassociated access terminal 520U by power control. In the meantime, the signal-to-noise ratio (APR) associated with the access terminal 520S falls below the required levels, which results in further packet errors on the uplink ii from the associated Terminal 520C access in the home femto node 510A. because of the very high-dispersion in the RT, this mechanism can take some time required for the femto node 510A to overcome the obstacles in the associated term-duplex terminal caused by an unassociated access terminal 520U by controlling power. In the meantime, the signal-to-noise ratio (APR) associated with the access terminal 520S falls below the required levels, which results in further packet errors on the uplink ii from the associated Terminal 520C access in the home femto node 510A. because of the very high-dispersion in the RT, this mechanism can take some time required for the femto node 510A to overcome the obstacles in the associated term-duplex terminal caused by an unassociated access terminal 520U by controlling power. In the meantime, the signal-to-noise ratio (APR) associated with the access terminal 520S falls below the required levels, which results in further packet errors on the uplink ii from the associated Terminal 520C access in the home femto node 510A.

To minimize the unexpected fall in ZIR in a desirable scenario, one of the implementation options may be increased the size of the control stage power on the ascending line and / in the transfer from the home femto node 510A to the associated terminal 510C access. However, with the usual upper limits on the size of the stage of power management, whichformed by the standards of communication, as there may be other violations in the system, if the system works with a very high stage size

power management. Thus, it is desirable to manage

the level of RH in the femto node 510.

To prevent unexpected jumps in the router due to an unexpected increase in the barrier generated by non-associated dash-termin terminals (for example, the interference caused by an unbounded 520U access terminal in femto-evil 510A), the noise factor NE may be increased or received signals may be reduced by adding some components of the loss on the route propagation (RI_) in the ascending line of i._.However, such an operation is performed in femto node withhigher levels of interference. For example, in the scenario shown in FIG. 5B, if both femto devices 510A and 510B increase the noise factor of NE or reduce it to the same value, the result will be higher levels of transmission power on the uplink line and for the two access terminals 520C and 520U. As a result, the problem of high RH occurring in femto node 510A is not solved.

According to an illustrative embodiment, a femto node showing a high RT, a femto node 510A in this scenario, increases its coefficient of noise NE or the level of attenuation until the femto node ceases to show high RH, the femto node 510B in this scenario maintains its own noise factor ΝΕ provided that it does not create a high level of noise outside the stooler. Thus, a method is provided for adjusting the noise factor of the NE or attenuating the presence of a high level of interference outside the wall in a particular femto node. According to the illustrative version of the implementation to control the obstacles in the wireless communication system, the rotor in a given time slot n can be expressed as follows:

Roth (l) = [Ios (l) + Ioh (n ^ o (n)] ^ o (n)

and

Yog (l) = £ Esci (n), iyipsiyi

where the EU is the total energy received by one user and.

Referring to FIGS. 11A, 11B, there is described a method for controlling interference in a wireless system using adaptive adaptation of noise factors and loss paths for adaptive adjustment of traffic loss losses for PT control. It should be noted that the tuning factor can be applied either to the attenuation in the ascending line or to the nF noise factor.

As shown in block 1104, the operations described in this document may take place periodically, as, for example, in the case of the next slot of time. For example, in each slot, the femto node 510 may perform the following method to provide interference control in the communication system. As shown in block 1104, various signals are measured and the levels are calculated. In particular, as shown in block 1106, the thermal noise coefficient: N0 (η) is measured in the femto node 510. The heat-noise coefficient N0 (η) is the dispersion of the thermal noise, which includes the noise factor (NE) of the femto node.

As shown in block 1108, the power of the general received signal Io (l) is measured. General power

The received signal Io (n) represents the generally accepted power taken in the femto node of all wireless devices for which the given femtovuzol is in their active set and from all non-wireless devices for which this femto-sol is not in their active the set As shown in block 1112, the Iogg cross-code is calculated in the cell (associate access terminal), which is the total accepted power taken in the femto node of all wireless devices for which this femto node is known to be in their active set. Calculated ri-ve hurdles inside the cell can be expressed as:

Yog (n) = Σ Esi (n) iyipSeiii

As shown in block 1110, the ratio of the energy of the received elementary pilot signal ECr (n) to the interference and noise of N (η) from all non-wireless devices for which the femto node is found in their active set are measured.

As shown in block 1114, the ri-ven interference outside the cell (non-associative access term) Ios (n) is calculated, which is the total received power taken in the femto-evil of all wireless devices for which the given sub-node is not in their active set . The calculated level of interference outside the cell can be expressed as:

Ιοο (η) = Ιο (η) -ΙθΓ (η) -NO (η).

As shown in block 1116, the relation between the level of interference taken outside the cell, to N0 (η) of the thermal noise ratio and the ratio of the maximum energy of the filtered accepted elementary pilot signal ESp (n) to the interference-plus-noise Nί (η ) for access terminals inside the cell. As shown in block 1118, the signal-to-noise ratio of the access terminal is filtered, measured in the form of the energy ratio of the received elementary pilot signal ECr (n) to noise and noise N (η) for all access terminals inside the cell, for example, with the use Filtration with infinite impulse-noitecharacteristics (IRP) in dB. Maximum filtered value for access terminals for which the femto node is in their active collection can be expressed as follows:

iyip-seIIi assezz (etipai i nits, (η))

As shown in block 1120, the signal-to-noise ratio is calculated for the level of interference received by the non-cell Ios and the heat-noise ratio N0 (η). The signal-to-noise ratio is also additionally filtered, for example, with the use of filtration with a finite pulse characterization (DIR) in dB. The calculated signal-to-noise ratio outside the cell (non-associated term-nal) can be expressed as follows:

Yus <p> ı = sig | Yus <p) N0 (η) & Νο (η)

As shown in block 1122, for terminals dos-dupe inside the cell are determined by the supposedaccepted barriers outside the cell beyond the admissible (target) value, with which can actually work the communication system, and the ratiomaximum of the excess energy of the received elemental tacho pilot to noise and noise. As it was told in block 1124, the excess amount for absorbing the energy of the received elementary pilot to noise and noise can be expressed in a tactical way:

with the above-stated permissible threshold value Εορνίίαίδί, expressed in units of dB.

As shown in block 1126, the amount of excess for an outside cell received by the level of interference ^^ exsev can be expressed as follows:

With the above-stated lower threshold value, the value is expressed in units of dB.

As shown in block 1128, the amount of additional losses on the propagation path is calculated (RDF, which should be used. As indicated in block 1130,

determine the possible adjustment for the loss path of distribution. Possible adjustments may be expressed as:

Ρ ^ -sazsi = = tax (Ρ ^ -axi1, Ρ ^ _asηсІ2, Pb-sep ^ s).

In relation to the definition of the values ​​of possible sub-rovings, the possible values ​​can be based on different characteristics or rules. For example, different potatoes can be expressed as:

(1) Ρ ^ αηη1 and Ρ ^ _αηсІ2 are intended for fast adjustment of RI_, based on high values ​​of Ερπ / Νί and Ios, exceeding the high porosity value.

(2) In the case of both Esp / Nt and Ios, there are lowerlimit limits, and PyAsAb is intended for slow decrease (attenuation) of RI_ so that it is not high without necessity.

(3) If there is only one active user in the cell, then there may be no reason for limiting Ios, since the control mechanism RoT can already control the PtoT level. Consequently, in this case, when there is only one user in the system, Ιο ^ ί8 ^ βί can be set to a very large value.

As shown in block 1132, the corresponding losses in the area of ​​distribution (the bulkheads can be used in accordance with the upper and lower limits of the adjustment for losses in the path of spreading RI_, expressed as:

Referring to FIG. 12, and also FIGS. 5A, 5B, operations related to reuse of subframe time to solve a problem associated with muffling and negative geometry will be described in detail. This illustrative embodiment employs methods and hardware to prevent silhouettes and negative-geometry effects, with the re-use of subframe time.

In one illustrative embodiment, if the radio interface allows the use of time division multiplexing, the transmissions may be scheduled in such a way as to eliminate time intervals with the effect of a negative geometry. For example, the femto node 510B can bind with an associated terminal 520U access during a time interval when the femto node 510A is silent. Similarly, the associated access terminal 520C can communicate with the femto node 510A during the time interval when the femto-break 510B is scheduled to silence the unassociated terminal 520U access. Such methods that use synchronization and scheduling approaches are found in systems that allow the use of time-division planning, such as IEEE. For example, since these control channels use the time multiplexing,

However, as discussed below, this is not applicable to radio interface technologies that do not allow the use of scheduling operations and time-division multiplexing, for example, technologies that use CMS control channels, including the IchRTT, the MSIUM and the NZRA .

In one illustrative embodiment, reuse the time-consuming sub-frame of the application-to-technology, where hybrid reuse of time can not be applied. In many cellular technologies, such as cSta2000 and MSYUM, the base station continuously transmits a pilot-channel and other channels of CMS management (for example, synchronization channels, calls, broad-band transmissions, etc.) used by ter-minals of access for various Goals, including Initial Scan and Access, Standby, and Channel Evaluation. Suchcontinuous transmission on the pilot-channel and service channels from the femto node can lead to a description of the above muffling

descending line, even if the source of muzzle no active traffic.

In one illustrative embodiment, the first step in the field is to overcome the situations continuously in operation, when the pilot channel and service calibres (for example, synchronization and call channels) of the desired femto node 510 can be received at the terminal 530. For example, FrameSta2000 divided into sixteen power management groups (RSO). To ensure the capability of receiving the pilot, a portion of the transmission on the pilot-channel and service channels is strobe.

As shown in FIG. 5B, the femto node 510A transmitting to the associated access terminals 520A-C carries out the transmission of such stolen frames (for example, in the periods of gating, the traffic is not transmitted in a straight line). In an unassociated Terminal 520U access during the gating period of the 520A femto node 5, the carrier / interference ratio, C / I, for transmission from the femto node 510B is substantially improved, which enables reception of the pilot channel 520J access and the synchronization channel from the femto node 510B , despite the fact that the negative geometry is in the 520U dos-duper terminal.

In one of the illustrative embodiments, the gating periods are planned in such a way that they do not overlap with each other. Thus, the femto node 510A and the femto node 510B can use non-overlapping subframes (or groups of power management). In one of the illustrative embodiments, by stroking (ie, the lack of transmission of traffic on a straight line), for example, 1/2, 2/3 or 3/4 subcaps, there may be a created pattern of reuse of the time division 2, 3 or 4. If pilot channel and service channels have significant redundancy, then for receiving a pilot channel, as well as for decoding service channels, it will be 3-6dB from the budget line for the pilot channel and service channels. However, it can be easily offset by increasing the power of the femto node 510 transmission,

In addition to the pilot channel and service channels, the same method of gating can be applied to the transmission of voice channels or data. In one of the illustrative embodiments, the femto node 510 strokes part of the every-frame frame transmission. If, for example, the part (for example, 1/2) that is turned off is less than the coding channel used when transmitting, for example, in the batch voice transmission of the cSta2000 line line, the standard format (PC3) uses a convolutional code at 1/4 , the 520 access terminal will have the ability to decode the packet, even when hacking half the packet. In order to avoid the need to know the geometry and to carry out the planning of non-overlapping gating intervals, the method described below is to prevent silencing and effects associated with non-negative geometry,

wireless communication with the use of repeated use of the time of subframes. As shown in block 1202, strobe sequences (or patterns) are identified, with each strobing sequence executing, for example, or eleven of sixteen power control groups (RCCs) for obtaining a reuse ratio of 5/16, or eight of the sixteen RCCs for obtaining a repeat coefficient use 2

String sequences can be chosen in the same way to minimize the mutual correlation between the pairs of strobing sequences of the femto nodes 510, which are potential sources of interference. As shown in block 1204, each femtovuzol 510 selects one of the strobe sequences. Though the femto node 510 may try to choose a stitching sequence that does not overlap with neighboring femto nodes, in general case selection does not necessarily lead to non-over-curve variants. However, this illustrative embodiment envisages a mechanism by which identification and selection of non-overlapping sequences can be identified.

As shown in block 1206, the access terminal 520 establishes an active connection to the femto node 510. In response to the connection, the access terminal 520 provides a "fast" backlink control of the downlink (line) power over each subframe, which allows the femto node 510 to select the desired non-overlapping strobe sequence.

In particular, as shown in block 1208, the femto-sol 510B transmits a sequence of frames, for example, to a voice / data channel to an access terminal 520, with no gating of all power control groups (RCCs). As shown in block 1210, the neighboring femto node 510A, which is a potential source of interference, is already communicating with the access terminals 520A-C using the technology of stroking the subframes, the 520-terminal terminal will observe interference on the sub-frame of the subframe when the gateway is transmitted to the adjacent femto node 510A (source of interference). Moreover, the access terminal 520 will also observe a different subset of subframes without interruption from the side of the neighboring femto node 510A, when the 5th antenna 510A performs the gating at this sub-set under frames

During subframes, on which the femto node 510An performs gating, the 520U access terminal will be able to observe, for example, low E / N0. As shown in block 1212, the feedback control of the downlink (line) power from the access terminal 520U indicates that the femto node 510B must increase the transmit power for specific subframes. Similarly, during sub-frames at which the 510A femto node 5 does not perform gating, the 520U access terminal will observe a high EB / NOI feedback control of the downlink (direct) power from the access terminal 520U, indicating that the femto node 510B should reduce the transmission power for specific subframes.

As shown in block 1214, the feedback control of the downlink (direct) line power in the sub-frames provided by the access terminal 520

in the femto node 510B, indicates which subframes are transmitted by the neighboring femto node 510A (source interference), strobed and for which the subframe strobe-tion is absent. Accordingly, such an instruction allows the Femtom node 510V to choose a strobe sequence (pattern) that does not overlap (is complementary) with a strobe sequence (patter-nom) selected by the neighboring femto node 510A (source of interference). Thus, the illustrative version of the implementation allows establishing the fact of using the stroke sequence (paterna) selected by the neighboring femto node 510A (source of obstacles).

Depending on the technology used, other considerations may additionally determine the types of recording sequences (patterns), the most suitable for use in technology, the processing of subframes. Moreover, since the existing access terminals can not determine whether the gating is applied to the downstream (direct) line, other considerations may be used to use the choice of strobing sequences (patterns) in which the shorter periods of "shutdown" alternate with shorter periods of "typing". Taking these considerations into account may reduce the impact on the way of estimating downlink (direct) channels and quality feedback feedback for channels used in existing access terminals. For example, in the case when eight subcaps of sixteen are completed,

In another illustrative embodiment, when choosing a stitching sequence, different considerations may be used for rotational variants in which the neighboring femto nodes 510 are not synchronized. Such a situation may arise, for example, if the FIE-510 IUU is not synchronized. In one illustrative embodiment, the implementation of non-synchronized femto nodes 510, instead of the use of alternating gangsters / unstressed subframes, may prove to be an integral adjacent arrangement of all or most of the worn / unstretched subframes. For example, in the case of the MSYUM system with fifteen 10-megapardacres per 10 ms or thirty subframes of 20 ms, it may be advisable for each femto node 510 to nibble nine consecutive subframes of fifteen and not to spoil six consecutive subframes Alternatively, when using 20ms frame,

In an alternative illustrative embodiment, other methods to overcome such a situation and to improve the C / I downlink are utilized by femto nodes 510, configured to transmit transmission through the pilot channel and service channels, if there are no associated terminals, and include the pilot channel and service channels on a periodic and / or very low power only in a period when associated access terminals 520 can perform a scan to search femto node 510.

Referring to FIGS. 13, 14, and also FIGS. 5A, 5B, operations related to the hybrid reuse of time for ro-linking the problem associated with muffling and negative geometry will be described in detail. This illustrative embodiment employs methods and hardware to prevent silhouetting and negative-geometry effects by employing hybrid re-use technology.

In an illustrative embodiment, if the radio interface allows time division multiplexing (eg, IEE-UO), transfers can be scheduled in such a way as to eliminate time intervals with the effect of a negative geometry. For example, the femto node 510B can be associated with an associated terminal 520U of the pre-stupa during a time interval when femto-sol 510A is not transmitted. Similarly, an associated 520S access terminal can communicate with the fem node 510A during the time interval, when the 520B terminal is scheduled for the lack of a 520U access terminal forwarding.

In an illustrative embodiment of the method of hybrid re-use of the Time, the downlink transmission is divided into separate groups by sodium time:

1) the transmission period on the synchronous channel of control (5СС),

2) the period of transmission of a limited cycle of NARO,

3) the period of transmission of an unlimited cycle of NARO.

FIG. 13 illustrates an illustrative time frame for a downlink that includes three different time periods throughout each cycle time of the synchronous control channel (WSS) with a length of 256 hour slots. In one of the illustrative embodiments, based on the separation of timeresources during the "unlimited cycle NARO", identified three different femto channels. As described more descriptively below, it is desirable that neighboring femto-evil 510 select different femto channels in such a way that they do not interfere with other adjacent femto nodes 510 (i.e., each femto node 510 selects a main femto channel other than a neighbor femto node 510). In the absence of interference from the neighboring femto node, a plurality of femto channels (complementary to the main femto channel) can be used by one femto node 510.

FIG. 14 illustrates a method for controlling passcodes in a wireless communication system employing hybrid reuse of time according to an illustrative embodiment. As shown in block 1402, when the power is turned on or other synchronization of the femto node 510, femto-sol 510 performs time synchronization with macro-networked network (for example, with macro access node node 560). As shown in block 1404, during timing synchronization with the macro cell access node 560, the femto node 510 performs the offset measurement (MZSSO) of the secondary channel synchronization (WSS) using the macro access node node 560 and the neighboring femto node 510.

Based on this measurement, femto node

510 identifies the prevailing NARO cycle with the most-

less obstacles, as shown in block 1406.

Preferential offset slot (RZO) is determined from

identified NARO preferred cycle.

As shown in block 1408, the main femto channel is selected. For example, an illustrative process of choice can be performed according to the following algorithm:

if tofRZO-MZSSO, 4) = 1, then femto-nal 1 is selected as the main femto channel,

if tofRZO-MZSSO, 4) = 2, then femto-nal 2 is selected as the main femto channel,

if tofRZO-MZSSO, 4) = 3, then femto-nal 3 is selected as the main femto channel.

After determining the femto channel, the femto node 510 can transmit traffic down (straight line). Transmissions, carried out by femto nodes 510, are limited in time to reduce the obstacles that are generated by transmissions of macrocells and otherfemot nodes. Transfer protocol femto node for different periods of transmission of macrocells, the period of transmission on the WSS, the period of transmission of a limited cycle NARO and the period of transmission of an unlimited CNR cycle, described below.

As shown in block 1410 and in FIG. 13, the MIDI transmission period 1302 is determined at the beginning of the skin cycle of the CPU 1304 (e.g., 256 slots) to enable the transmission of the ASC shift (for example, the first 32 slots in each WSC cycle). In one Illustrative implementation options determine two sub-periods 1306 and 1308, based on the NARO cycle: a predominantly offset slot and non-superior shifting of the slot.

In a NRO loop with a predominantly displacement slot, the femto node 510 transmits the VSS information. This ensures the reliable transmission of the control channel information and provides the opportunity for the access terminals 520 to be connected to and disconnected from the femto node 510. During the NAR cycle, unmatched offsets of the slots, femto node 510 do not convey traffic on the downlink (direct) line, so that a minimum number of over-code is created for neighboring macrocells and adjacent femtovuzlas transmitted by the WSS. With these offsets, the pilot channel and the MAC channel are used part of the downlink power, which allows these channels to function successfully.

As shown in block 1412 and in FIG. 13, during the transmission period of the restricted NAR0 loop, the fem node 510 is allowed to transmit the downlink (direct) traffic in the NARO loop with RLS, while sensitivity to traffic delay is given an absolute priority over other types As shown in FIG. 13, the transmission period of a limited NAR cycle allows for the transmission of any femto node so that traffic-sensitive traffic (such as VoIP) is not subject to excessive delays. In one example, during the transmission period of a limited NARO cycle, if the requested JRC is zero, then one-user package can be used 38.4kb / s. If JRC is zero or erased, then compatible types of user packages such as a single-player package (ZIR) 38.4kb / s can be used.

or 256/512/1024 bit multiuser package (MiR) (similar display case for erased IPO)

In one of the illustrative embodiments, the traffic of the downstream (direct) line can also be transmitted in the NARO MZSSO cycle. In one embodiment, the neighboring femto node 510 may also be used. Use this loop (i.e., shunt protection against interference). During the cycle of NARO with other displacements of slots, femto nodes do not transfer the traffic of the downstream (direct) line (reuse of time), but part of the power of the downstream line can be allocated to the pilot channel and the MC channel to ensure the successful work of these channels.

As shown in block 1414 and in FIG. 13, during a period of transmission of an unlimited number of NRAOs, the fetch node is allowed to transmit the downlink traffic in all four NARO cycles. At the beginning of the period, the power of the downlink can slowly increase to ensure the ability of the functioning of the node to predict the speed of the access terminal. In one of the illustrative embodiments, for an additional increase in the velocity increase of the values ​​of ELES, can be used-Xia length ELES, which is 1 slot. Because of the conservative behavior of the prediction node, if at the beginning of the transmission period of an unlimited cyclone, the mobile device asks for a zero ELS, the femto node 510 can transmit compatible packet types (a multi-player package or one-user package of 38.4kb / s). Exept this,

The principles outlined in this document can be implemented in a node (for example, devices), which uses various components for implementing communication with at least one other node. On Fig.15 shows several components of the samples, which can be used to facilitate communication between nodes. In essence, FIG. 15 shows a wireless device 1510 (for example, an access point) and a non-stop device 1550 (for example, a terminal access) of the 1500 MIMO system. In device 1510, traffic data for multiple data streams is provided from the source 1512, the data to the data transfer processor 1514 (TX).

In some embodiments, each retransmission is transmitted through the appropriate transmit antenna. TX data processor 1514 formats, encodes and executes data traffic interleaving for each data stream, based on a specific schema encoding selected for such a data stream, to provide encoded data.

The coded data for each data stream may be multiplexed using STM methods that use pilot data. Pilot data are usually a known pattern of data, which is processed in a known manner and can be used in the receiver system for evaluation

channel response. Then the multiplexed pilot cached data for each data stream is modulated (i.e., displayed in symbols), based on a specific modulation scheme (eg, VRZK, OZRK, M-RPC or M-OLM) selected for such data streams to provide modulation symbols . Data rates, coding and data modulation for each data stream can be determined by the commands executed by the processor 1530. Data memory 1532 may store program codes, data, and other information used by the processor 1530 or other components of the 1510 device.

Modulation symbols for all data streams are provided in the TM MIMO processor 1520, which can perform additional processing of simulation symbols (for example, for OP1EM). Subsequently, the TX MI-MO processor 1520 provides Nτ the streams of the symbols of the mutation in the Nt of the transmitter receivers (CSCRs) 1522A-1522T. In some embodiments, the TX MIMO-processor 1520 applies to the stream symbol data and to the antennas through which symbols are transmitted, weighing to form a beam.

Each transceiver 1522 receives and processes a corresponding symbol stream to provide one or more analog signals and additionally performs conditioning (for example, amplifies, filters and converts from an increase in frequency) of analog signals to provide modulated signals suitable for transmission over MIMO channels. Then, Nt modulated signals from transmitters 1522A-1522T transmit throughNT antennas 1524A-1524T, respectively.

In apparatus 1550, modulated transmitted signals are received with NK antenna 1552A-1552P, and the received signals from each antenna 1522 are provided to the respective transmitter receiver (CSCR) 1554A-1554P. Each transceiver performs conditioning (for example, filters, amplifies and reduces frequency) from received signals, digitizes the conditioned signals to provide samples and listens to sampling to provide the appropriate "adopted" character stream.

Then, the data receiving processor 1560 receives and processes NK received symbol streams from the NNs of the transmitter receivers 1554 based on the processing method for a specific receiver to provide Nτ of "detected" symbol streams. The RX data processor 1560 then performs demodulation, rotational interleaving, and decoding of each implemented character stream to recover the data traffic for the data stream. Processing by the help of the RX-processor 1560 of the complement-processing data performed by the TX MHMO-processor 1520 and the TX-processor 1514 of the data in the device 1510.

The processor 1570 periodically determines which matricts the previous coding should use (see description below). The processor 1570 creates a feedback message for the return line that contains the part of the index matrix and part of the rank value. The data memory can store the program, code, data, and other information used by the processor 1570 or other components of the device 1550.

43

97033

44

The backward message may include the type of information relating to the communication link and / or the received data stream. The return line message is then processed by the TX processor 1538, which also receives traffic data for multiple data streams from the data source 1536, modulated by the modulator 1580, is conditioned by the transmitter transmitters 1554Α-1554Ρ and transmitted back to the device 1510.

In apparatus 1510, modulated signals from a device 1550 are transmitted using antennas 1524, are conditioned by receivers-transmitters 1522, demodulated by a demodulator (SEM) 1540, and processed by a PX-processor 1542 of data for extracting a reverse message transmitted by the device 1550. Then, the processor 1530 means which pre-coding matrix you use to determine the formulation of weight coefficients, then processes the output message.

FIG. 15 also shows that communication components may include one or more components that perform interference-control operations as described in this document. For example, the interference control component 1590 may interact with the processor 1530 and / or other components of the device 1510 for sending / receiving signals to / from another device (e.g., device 1550) as disclosed herein. Similarly, the interference control component 1592 interacts with the processor 1570 and / or other components of the device 1550 for transmitting / receiving signals to / from another device (for example, device 1510). It should be noted that for each device 1510 and 1550, the functionality of two or more of the described com ponents can be provided by one component. Example,

The principles outlined in this document can be implemented in different types of communication systems and / or system components. In some embodiments, the principles disclosed in this document can be applied in a system with a multiple access, capable of maintaining communication with multiple users by sharing the available resources of the system (for example, by determining one or more bandwidth, transmission power, coding, interleaving, etc. .) For example, the principles outlined in this document can be applied to any one or a combination of the following methods: multi-channel access with code division of channels (ΟΜΜΑ), multi-station access with code division of channels (MOPP), Wideband APM (W-APM), high-speed patch systems access (H3PO4, H3PO4 +),

Choi (ZS-PII), multiple-access systems with orthogonal frequency diversity (ΟΜΜΑ) or other multiple access methods. Wireless communication systems using the methods disclosed in this document can be developed for implementing one or more standards, such as I3-95, Ebte2000, I3-856, WCMM,

Т ^ 3С ^ МА and other standards. The network C ^ МА can realize a radio method, such as a universal ground radio access (υΤΡΑ), fuck2000 or some other methods. υΤΡΑ includes SH-C ^ МА and low pass-through time of elementary parcels (БСР). The method of fuck 2000 covers standards Ι3-2000, Ι3-95 and Ι3-856. The TIMA network can implement a rhythm method, such as the global digital standard for mobile cellular communication (O3M). The MIMO device can realize a radio method, such as the extended υΤΡΑ (E-φΤΡΑ), ΕΕΕΕ 802.11, ΙΕΕΕΕ2016, ΙΕΕΕ 802.20, RIAZ-APMY®, etc., ΤΤΑΡ, Ε-υΤΡΑ and ΟΜΜ are part of the universal system of mobile telecommunications (υΜΤ3 ) The principles outlined in this document can be implemented in the system of 3SRR of long-term development φΤΕ), the system of supermobile broadband access (υΜΒ) and other types of systems. ΕΕΕ is a realization of υΜΤ3, which uses Ε-υΤΡΑ. Although some variants of this disclosure can be described by means of the 3SRR terminology, it is necessary to take into account that the methods described in this document may be applied to the methods of the 3SRR (PIXTH, PATI, 5, 6, 6, 7), as well as the methods of 3SRP2 (ΙχΡΤΤ, ΙχΕν-ΟΟ ΡθΙΟ, ΡθνΑ, ΡθνΒ) and other methods.

The principles outlined in this document maybe implemented (for example, implemented or implemented with help) in a plurality of devices (such as nodes). In some embodiments, an implementation node (e.g., a wireless node) implemented in accordance with the principles disclosed in this document may contain an access point or an access terminal.

For example, an access terminal may contain, be implemented in the form or known as user equipment, a subscriber station, a subscriber unit, a mobile station, a mobile device, a mobile node, a remote station, a remote terminal, a user terminal, a user agent , a user device, or known under some other terms. In some embodiments, the access terminal may include a cellular tele-phone, a wireless telephone, a session initiation protocol (3 ^), a wireless LAN loop, a personal digital helper ^ ΟΑ), a portable device that has a wireless capability connection, or some other suitable processing devices connected to a wireless modem. Consequently, one or more options embodiments disclosed in this document may be implemented on the phone (for example,

devices), global positioning system devices, or any other suitable device that is designed to communicate through a wireless environment.

An access point may contain, may be implemented in the form of, or may be known as, EOBE B, radio network controller (PNO), base station (VZ), base radio station (RVZ), base station controller (VZS), base transceiver (TP), receiver-transmitter (TP), radio-transmitter, radio router, basic service set (RS), extended service set (ESA) or can be known under other similar terms.

In some embodiments, the node (for example, the access point) may have an access node for the communication system. Such an access node can provide, for example, the ability to connect to a network (such as a global network, such as the Internet or the cellular network) via a wireless or wireless network connection. Therefore, the access node can provide the opportunity to another node (for example, a terminal access) to access the network or some other functional medium. In addition, it should be noted that one or both nodes may be portable or, in some cases, relatively non-portable.

Also, it should be noted that wireless cinematography may have the ability to transmit and / or receive information via non-wire way (for example, via wired connection). Thus, the receiver and transmitter, as described in this docket, may include the appropriate components of the interface (for example, electronics or optical interface components) for communication with the non-wireless environment.

A wireless host can communicate through one or more wireless communication lines that are based or otherwise supported by any suitable wireless communication method. For example, in some embodiments, a non-wired node may be associated with a network. In some embodiments, the network may provide a local area network or a global network. The wireless device may support, or in other cases, use one or more methods from a plurality of wireless communication methods, protocols or standards such as those described in this document (e.g., COMA, TYUMA, ORUM, OryMa, MIMAK, Mi-RI, etc.). Similarly, the wireless host can support or in other cases use one or more of the plural appropriate modulation or multiplexing. Thus, the wireless node may include appropriate components (eg, radio interfaces) for establishing and communicating from an interconnect or several wireless networks using the above or other wireless methods. For example, a wireless hub may contain a wireless transmitter with associated receiver and transmitter components, which may include different components (for example, signal generators and signal processor-

ri), which facilitate the implementation of communication through the wireless environment.

The components described in this paper can be implemented in numerous ways.
