BACKGROUND OF THE INVENTION

TECHNICAL FIELD

This application invention relates generally to the field of communications, in particular but not exclusively, to configuring a communications node.

INTRODUCTION

Large-scale wireless communication system deployed to provide various types of communication (eg, voice communications, data exchange, multimedia services, etc.), numerous customers. Since there is a rapid increase in demand for high-speed data and multimedia services, it is strongly required to implement effective and reliable communication systems with enhanced performance.

To complement the conventional base station the mobile phone network (eg, macrocells) can be deployed (eg, installed in the subscriber's home) base stations with a small area of ​​action to ensure more reliable wireless coverage indoors to mobile devices. These small base stations are generally known as the zone of action of the access point base stations, home nodes B (Home NodeBs) or femto (femto cells). Typically, such base stations with small area action connected to the Internet and the mobile operator network router through a digital subscriber line (DSL) or cable modem.

Practically, the base station with a small area of ​​action can be deployed in a mode of "ad-hoc" (self-organizing ad hoc (ad-hoc) networks), and in relatively large quantities. Consequently, there exists a need to provide improved methods for configuring such base stations.

DETAILED DESCRIPTION

Below is a description of various aspects of the disclosure of the invention. It should be apparent that the invention herein set forth may be embodied in a wide variety of options and disclosed herein that any specific structure, function, or both of them are merely representative. Based on the above the invention herein, one skilled in the art will appreciate that the aspect of the invention disclosed herein may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways. For example, the apparatus may be implemented or a method may be practiced using any number of aspects of the invention set forth herein. In addition, such an apparatus may be implemented or such a method may be practiced using other structure and other functionality or using a structure and functionality in addition to one or more aspects set forth herein of the invention or which are different from what they . Furthermore, an aspect of the invention may include at least one element of a claim.

FIG. 1 illustrates several nodes in the exemplary communication system 100 (which is, for example, part of a communication network). For illustrative purposes, the description of the various aspects of the disclosure of the invention given with reference to one or more access terminals, access points, and network nodes that communicate with each other. However, it should be understood that the idea of ​​the invention set forth herein may be applicable to other types of devices or other similar devices that are links using different terminology. For example, the access point according to the inventive concept described herein may be implemented or may be referred to as a base station, eNodeB node, home node eNodeB (Home eNodeB), etc. Besides, the access terminal according to the inventive concept described herein may be implemented or may be referred to as a mobile station, user equipment, etc. Furthermore, the network node may be implemented or may be referred to as a configuration server; providing entity operation, accounting and administration ("OAM"); Administrator mobility, etc. Another sample of the terminology set forth in the following description.

Access points in the system 100 provide one or more services (e.g., network connectivity) for one or more wireless terminals (e.g., for access terminal 102) that may be mounted within the corresponding geographical area, or which may move throughout the in the area. For example, at different points in time the access terminal 102 may communicate with access point 104 or access point 106. Each of the points 104 and 106 may access to communicate with one or a large number of network nodes (for convenience shown as a network node 108) to facilitate wide area network connectivity. These network nodes may be nodes of different species, such as, for example, one or more objects of a radio network and / or core network (e.g., implemented as described above, or any other suitable network entity).

In some aspects, the configuration of the access point, such as, for example, access point 104 may preferably be achieved by providing a capability to configure the access point. For example, in a network in which there are a relatively large number of access points, more effective functioning of the entire network can be the variant in which each access point has the ability to self-configuration, at least to some extent. Thus, from the network operator (e.g., centralized objects managed by the operator) can be removed, at least part of the load to determine the proper configurations and tracking configurations for all these access points.

In Example from FIG. 1 access point 104 includes a configuration controller 110, which configures the access point 104. Here, the configuration of the controller 110 may provide one or more of the configuration parameters that access point 104 uses for the operations relating to the communication. For example, controller 110 may provide configuration settings for configuration of the transceiver 112 of the wireless communication, such as, for example, an identifier of the pilot signal, the operating frequency and transmission power.

In some embodiments, configuration controller 110 determines the configuration parameters based on the configuration (configuration) of at least one other access point (e.g., neighboring access points). To this end, the configuration controller 110 can receive configuration information from the other point (the other points) of access and / or information that may be used to obtain configuration information from the other point (the other points) access.

In some cases the access point 104 may communicate with the access point 106 to determine the configuration of the access point 106. For example, the access point 104 may communicate with the access point 106 through the backhaul (backhaul) (for example, via the network node 108). As a more specific example, the eNodeB may receive the report (e.g., via the X2 interface) physical cell identifier (PCI), used by the neighboring node eNodeB.

Moreover, access point 104 may collect information related to the configuration directly from the access point 106 by radio signals. For example, access point 104 may include a downlink receiver (FIG. 1 not shown), which receives signals transmitted by access point 106. As a more specific example, the identifier PCI, used node eNodeB, can be "heard" by the other radio node eNodeB receiver via the downlink.

Access point 104 can also collect information relating to the configuration via the access terminal (e.g., when the access terminal 102 served by the access point 104). For example, the access terminal 102 may forward the information collected them from the access point 106 (e.g., information obtained from the transmissions made by the access point 106) to point 104 access. As a more specific example, the user equipment may report identifier PCI, used node eNodeB, to another node eNodeB.

In some cases the access point 104 may receive information related to the configuration of the network node 108. For example, network node 108 may identify any neighboring access point 104 and send the information about the neighbors in the access point 104. Then, the controller 110 uses the configuration information about neighbors to determine the configuration specified neighbor (these neighbors).

In some instances, the network node 108 sends a list of identifiers of the pilot signals in the access point 104. Then the access point 104 may select an identifier pilot from the list. For example, access point 104 may select an identifier from the list of pilot randomly selected identifier or a control signal based on a certain criterion or criteria. Here, the access point 104 may exclude any identifiers of the pilot signals used by other access points (such as neighboring access point) of its choice.

As a more specific example, the object list may report OAM identifier values ​​in the PCI node eNodeB. Said list can be individual for each particular cell. Then, the eNodeB can select the PCI cell ID from the list of IDs PCI. For example, the eNodeB may choose the identifier PCI from the list of identifiers PCI randomly.

In some cases, the eNodeB can limit the received list by removing the PCI identifier reported by the user equipment, the reported neighboring node eNodeB, "heard" by radio via a downlink obtained by any other method or obtained by a combination of two or more of these methods. Then, the eNodeB can choose PCI ID value of a limited list of PCI IDs randomly or select the ID from a limited list of PCI in any other way.

In some cases the access point 104 may provide information to the configuration server (for example, depicted as a network node 108) to facilitate the configuration server to provide configuration information for the access point 104. For example, access point 104 can determine its position and send the appropriate location information to the network node 108. Network node 108 may then determine the appropriate configuration information based on the location and send the configuration information in the access point 104, wherein the configuration controller 110 uses this configuration information to configure the access point 104.

In some cases, the configuration server (for example, depicted as a node 108 network) sends the access point to a different configuration server for configuration information. For example, upon receipt of a request to access point 104 to receive information about the network configuration, node 102 may forward the access point 104 to another network node (e.g., another configuration server). Such redirection may be based, for example, the location of the access point 104 and / or workload of one or more configuration servers.

Configuration operation, such as those described above can be preferably used in the network 200 shown in FIG. 2, where some access points provide macro zones of service and other access points provide smaller coverage. There macro zones 204 service can be provided, for example, macropoint access the cellular network covering a large area, such as a communications network of the third generation (3G), commonly referred to as cellular macro network or a wide area network (WAN). Also, smaller service area 206 may be provided, for example, network access points, or medium-scale apartment buildings, usually referred to as local area network (LAN). When moving the access terminal (AT) in a service network of an access terminal in specific places may perform the access point providing service macro zones, whereas in other service areas that access terminal may perform an access point for smaller service area. In some aspects, an access point with a smaller coverage area may be used to provide incremental increase in capacity, service areas in the building and different services, all this leads to a more robust user experience.

In the description herein, the network node (e.g., access point) that provides coverage area of ​​a relatively large area may be referred makrouzlom network, while the network node providing the service area of ​​a relatively small area (e.g., flat) may be cited femto nodes. It should be understood that the idea of ​​the invention set forth herein may be applicable to network nodes associated with other types of coverage areas. For example, pikouzel can provide the service area in less than macroregions, and more than femtooblast (eg, service area in a commercial building). In addition, the relay node can provide a wireless coverage area, which allows the access point to communicate with other nodes in the network. In other words, the relay node may provide wireless backhaul that facilitates connectivity, such as network node or another relay node. In various applications, other terminology may be used to name makrouzla, femto nodes or other network nodes such as an access point. For example, makrouzel may be configured or referred to as an access node, base station, access point, node eNodeB ("eNB"), macro cell, etc. Besides femtouzel may be configured or referred to as a home NodeB node, home node eNodeB, access point base station, the base station access point, eNodeB node, femtocell, etc. In some embodiments, the network node may be associated with one or more cells or one or more sectors (e.g., it can be divided into one or a greater number of cells or one or more sectors). A cell or sector is set in accordance makrouzlu, femto nodes or pikouzlu, may be referred to, respectively, the macrocell, picocell or femtocell. For convenience, the description herein generally can be referred to the operation and components of the access points and femto nodes. It should be understood that these operations and components may also be applicable to other types of nodes (e.g., relay nodes and pikouzlam).

In Example from FIG. 2 identified several zones tracking 202 (or routing areas or location areas), each of which includes several macro zones 204 service. Here, the field service areas associated with areas 202A, 202B and 202C tracking, are outlined by thick lines, and macro zones service 204 are depicted as hexagons. As mentioned above, the tracking areas 202 also may include femtozony 206 service. In this example, each of femtozon service 206 (e.g., service femtozona 206C) is depicted within one or more macro zones service 204 (e.g., macro zones 204B Service). However, it should be understood that femtozona service 206 may not be located entirely within a macro zones 204 service. Moreover, within a given tracking area 202 or macro zones service 204 can be defined one or more pico or femtozon service (not shown).

The network may deploy a large number of access points such as femto nodes that shown by small cells in macro zones 204A maintenance. In this case, the idea of ​​the invention set forth herein can suitable be used to configure these access points. In view of the above brief review, the following will describe various methods that can be used to configure access points in accordance with the inventive concept herein described, with reference to FIG. 3 - FIG. 11. The Drawings Fig. 3 - FIG. 6 includes, in some aspects, the operations and the components that can be used to determine the identity of the pilot signal to be used by the access point. Drawings FIG. 7 - FIG. 9 includes, in some aspects, the operations and the components that may be used to configure the access point based on the configuration of at least one other network node. FIG. 10 relates in some aspects to operations that may be used to provide configuration information to the access point. FIG. 11 relates in some aspects to operations that may be used to direct the access point in the configuration server.

For illustrative purposes, the operations shown in FIG. 3, FIG. 5 - FIG. 7 and FIG. 9 - FIG. 11 (or any other operations discussed or defined herein) may be described as being performed by specific components (e.g., components of the system 100, the components shown in FIG. 4, or the components shown in FIG. 8). However, it should be understood that these operations may be other types of components and may be performed using a different number of components. It should also be understood that this embodiment may not be used one or more of the operations described herein.

FIG. 4 and FIG. 8 illustrates several sample components that may be incorporated into nodes such as, for example, an access point, a network node and an access terminal to perform configuration according to the inventive concept presented here. The described components also may be incorporated into other nodes in a communication system. For example, other network nodes (e.g., other access points) in a system may include components similar to those described for access point 402 and / or access point 802 to provide similar functionality.

As shown in FIG. 4, the access point 402 and the network node 404 (e.g., the configuration server) may include transceivers 406 and 408 respectively for communicating with other network nodes. The transceiver 406 includes a transmitter 410 for transmitting signals (e.g., messages) and a receiver 412 for receiving signals (e.g., containing information related to the configuration). The transceiver 408 includes a transmitter 414 for transmitting signals and a receiver 416 for receiving signals. Similarly, access point 802 and the network node 804 (e.g., the configuration server) shown in Fig. 8 may respectively include a transceiver 806 (including transmitter 808 and receiver 810), and transceiver 812 (including transmitter 814 and receiver 816). Access terminal 818 shown in FIG. 8 may also include a transceiver 820 (including transmitter 822 and receiver 824).

The network nodes shown in FIG. 4 and FIG. 8, also include other components that may be used in conjunction with the operations of the configuration according to the inventive concept presented here. For example, as shown in FIG. 8, point 802, the access node 804 network and the access terminal 818 may include respective controllers 826, 828 and 830 connection for managing communication with other nodes (e.g., by transmitting and receiving messages / indications) and for providing other related This functionality according to the inventive concept presented here. In addition, as shown in FIG. 8, one or more components, which is the point 802, the access node 804 network and the access terminal 818 may include a controller configuration indicated respectively numerals 832 (which, for example, comprises an agent checkpoint integration, IRPAgent), 834 ( which, for example, comprises means administration Integration checkpoint, IRPManager) and 836, which are designed for performing operations associated with configuring and for providing other related functionality according to the inventive concept presented here. Typical operations of other components shown in FIG. 4 and FIG. 8, described below.

For the convenience of the network nodes shown in FIG. 4 and FIG. 8 depicts includes components that may be used in the various examples described below with reference to FIG. 3 - FIG. 11. In fact, in this example, may not be used one or more of the illustrated components. As an example, in some embodiments, the access terminal 818 may not include collision detection means 838 and / or controller 836 configuration. As another example, in some embodiments, network node 804 may not include one or more of the following components: a controller configuration 834, means 840 or means determining 842 neighboring configuration server selection. As another example, in some embodiments, access point 802 may not include the positioning means 844.

This host may also contain one or more of the described components. For example, a network node may contain a set of components that constitute the transceivers that enable the node to operate simultaneously on a plurality of frequencies to frequencies and / or allow the node to communicate via different technology types (n For example, technology wired and / or wireless connection).

Referring now to FIG. 3 and FIG. 4, the inventive concept set forth herein may be used to configure an access point identifier by a control signal based on the identifier of the pilot signal to be used (identifier control signals used), at least one other access point. By using this scheme the access point in the network can make a choice (e.g. selection of produce off-line) control signal identifiers in a distributed fashion. Consequently, it can be reduced or eliminated the possibility of conflicts of identifiers of control signals in the network (e.g., when the network node "hears" a plurality of access points transmit the same pilot identifier). Furthermore, this can be accomplished without the use of centralized means of administration that assigns and keeps track of all the symbols of pilot signals used by all the access points in the network.

Pilot identifier can take various forms and may be referred to using different terms in different embodiments. For example, the identifier of the pilot signal may be referred to a cell identifier ("cell ID"), a physical cell identifier ("PCI"), or primary sequence of the scrambling ("PSC"). Besides pilot identifier can be associated with a pseudorandom noise sequence ("PN-sequence"), available in the control signal.

As shown by block 302 of FIG. 3, in some embodiments, the configuration server (e.g., network node 404 of FIG. 4) determines a list of identifiers of the pilot signals that can be used by a particular access point (e.g., access point 402), and sends said list to the access point. In Example from FIG. 4, these operations can be performed by the controller 418 configuration.

Here is a list of identifiers of control signals may comprise a subset of (e.g., 10 IDs pilot signals) from a set consisting of all identifiers of the pilot signals (e.g. pilot signals identifiers 512) defined for a given network. In some embodiments, said range of values ​​comprises a list of identifiers of the pilot signals.

A list of identifiers of control signals may be configurable by the operator. In some cases, this list can be used throughout the network operator (for example, the same list can be assigned a set of access points in the network). In some cases, for a variety of access points can be given a unique lists. For example, each access point in the network can be assigned its own list (however, these lists may not be unique).

In some embodiments, the operator may partition the space ID of the control signals to different subsets. The space identifiers of control signals can be divided based on various criteria.

In some embodiments, the control signal identifier space is divided into different subsets for different types of access points. For example, macropoint access can be assigned a first subset of identifiers of control signals (eg, control signals IDs with numbers 0-49), femto nodes can be assigned to a second subset of identifiers of control signals (eg, control signals IDs with numbers 50-499), and mobile access points can be assigned to a third subset of the ID of the control signals (eg, control signals identifiers with atomic numbers 500-511).

In some embodiments, the control signal identifier space is divided into different subsets on the basis of the transmission power of access points. For example, an access point with a higher capacity (eg macropoint access) can be assigned a first subset of identifiers of control signals, and access points with a lower capacity (eg, femto nodes, pikouzlam or relay nodes) can be assigned to a second subset of identifiers of control signals.

In some embodiments, the control signal identifier space can be divided into different subsets based on the location. For example, it can be given different subsets of identity controls to different geographical areas. Thus, a subset of identifiers of the pilot signals assigned to a particular access point may depend on the location of the access point.

In view of the above, in some embodiments, the configuration server operation performed in block 302 may be based on information received from the configuration server 402 access point. For example, at some point in time (e.g., after the access point 402 are connected to a network of the Internet), the access point 402 using its network connectivity to communicate with the network node 404 and the transmission of said information.

The access point 402 (e.g., positioning means 420) may determine the information indicating the location of the access point 402, and send this information to the network node 404. This information may take various forms. For example, information indicating the location of the AP may indicate at least one of the following parameters: the city in which is located an access point, the state in which is the access point, a country in which there is an access point macropoint access that serves the access point, the zone is associated with an access point, a cell to which the access point communicates, network ID, or information about the operator, which corresponds to cell coordinates, obtained through Global Positioning System (GPS), geographic location or street address.

Additionally or alternatively, the access point 402 may send information indicating the type of access point 402 to the node 404 network. As described above, this information may take various forms. For example, the type information may indicate one or more of the following parameters: the class of devices (e.g., femto-, macro-, moving, etc) for access point 402, a power class (e.g., high power, low power, and etc.) to the access point 402, an access point is imposed by the constraints (e.g., according to the inventive concept described herein), whether the access point is a stationary or mobile, or any other characteristic of the corresponding (any other characteristics appropriate) access point 402.

In this case, the network node 404 (e.g., configuration controller 418) may determine a list of identifiers of control signals for use by the access point 402 based on the information it receives from the access point 402. In some aspects the node 404 may use a network identifier value intervals of the pilot signal provided in advance by the operator to select the proper range of values ​​of the control signal identifiers for use by the specified node, and / or for use in a specified location.

As mentioned above, in some embodiments may not utilize some or all of the operation unit 302. For example, in some cases, the lists of identifiers of the pilot signals (e.g., ranges of values) are standardized. In this case, the network node 404 may simply send a standard list of identifiers of the pilot signals in the access point 402. In an alternative embodiment, access point 402 may be configured with a list of identifiers of the pilot signals, whereby the access point 402 does not receive this information from the network node 404.

As shown by block 304 of FIG. 3, the access point 402 (e.g., identifier determination means 422 control signal) determines at least one identifier of the pilot signal used by at least one other access point. For example, the access point 402 may determine which control signal identifiers used by its neighbors.

In some embodiments, the access point 402 (e.g., controller 424 neighbor discovery) can perform detection of adjacent devices to identify its neighbors. As will be discussed in more detail below, the access point 402 can detect neighbors within one hop network or neighbors within several network hops (e.g., two-hop network, three-hop network, etc.). In the latter case, the access point 402 may choose to view a radius of two, three or more-hop network to obtain identity information of a control signal from the more distant neighbors.

In some embodiments, access point 402 collects configuration information from its neighbors by neighbor discovery. For example, a discovery request neighboring devices issued by the controller 424 detect neighboring devices, point 402 access can be obtained from neighboring access points (e.g., neighbor within one hop network, or within a few hops network) prompted the discovery of neighboring devices, which includes an identifier of the pilot signal used by said adjacent access point. This neighbor discovery operation can be performed, for example via backhaul.

In some embodiments, access point 402 may collect information about the identity of the pilot signal of its neighbors from a server (e.g., node 404 network). For example, the network node 404 (which is, for example, the means 426 determine the neighbors) that can store information independently or access this information upon request. In this case, the network node 404 may send the ID information of the pilot signal in the access point 402 in response to a request from the access point 402. In some aspects the node 404 may identify the network provides information about the identity of the pilot signal based on the location of access point 402. For example, the access point 402 may include in its request for information, indicating its location. In this case, the node 404 may identify the network access points located in said proximity, and determine which identifiers pilot signals they use. Furthermore, the network node 404 may take into account the transmission power of the access point in determining whether the pilot signals transmitted by the APs to be taken network node, which also receives control signals 402 from the access point. Thus, the access point 402 may be sent to only those identifiers of the pilot signals that may potentially cause a conflict identifier control signals.

In some embodiments, the access point 402 may initially get a list of their neighbors and then spend the discovery of neighboring devices to access points listed in the list. For example, the network node 404 (e.g., means for determining the neighbors 426) may send a list to the access point 402 based on the information about the location of the access point 402 (which, for example, may be provided in the network node 404, access point 402). In addition, the access terminal is associated with a point 402 access (for example, it serves) can send to a point 402 to access a report that shows which access point, the access terminal "hears" is currently (ie, receives signals from them), or "I heard" before.

In some embodiments, the access point 402 may determine the ID of the control signals used by its neighbors, without making a formal discovery of neighboring devices. For example, the access point 402 may include a receiver downlink (e.g., shown as a receiver 412) that is configured to detect pilot signals from neighboring access points. Thus, the access point 402 may receive information about the configuration of radio communication. In this case the point 402 access may determine the identifiers of the pilot signals used by these neighboring access points based on the detected signals (e.g., based on the PN sequence derived from the received pilot signal), and possibly, but not necessarily, define identifiers neighbors (e.g. by analyzing the information in other messages sent on the downlink).

In some embodiments, access point 402 may receive the identifier of the pilot signal or other information about the neighbors of the access terminal (e.g., access terminal 102 shown in FIG. 1). For example, the access terminal associated with the access point 402 may send a report to access point 402, wherein said control signals received by the access terminal. Here, the access terminal can receive information (e.g., the identifier of the pilot signal PN sequence or other information identifying the access point) from the received signals and their forward this information to the access point 402.

As shown by block 306 of FIG. 3, the access point 402 (e.g., identifier selection means 428 control signal) selects the identifier of the pilot signal to be used by the access point 402 based on the identifiers of the pilot signals identified unit 304, and a list of identifiers assigned to the control signals, if applicable. For example, the access point 402 may choose from a list of identifier assigned pilot signal, which does not generate any conflict with the identifier of the pilot signal used by the neighboring access points (e.g., is not identical with it).

Access point 402 may attempt to avoid conflict with the ID of the control signals its immediate neighbors (such as neighbors within a radius of one-hop network) and, possibly, but not necessarily, the neighbors within a few hops network. Detection of neighboring devices within a radius of several network hops in greater detail below with reference to FIG. 5 and FIG. 6.

Access point 402 may organize identifiers control signal of its neighbors in several groups and using these groups during the selection control signal identifier. Such groups can be arranged in various ways. For example, the first group may include the identifiers of the pilot signals "hear" the access point 402 and / or identifiers of the pilot signals reported by the access terminals associated with the access point 402. The second group may include the neighbors at a distance of two hops networks detected during the detection of adjacent devices, but only those neighbors that have been recognized through the neighbor list provided by neighboring femto nodes (e.g., access points having low power). A third group may include the neighbors at a distance of two hops networks detected during the detection of adjacent devices, but only those neighbors that have been recognized through the neighbor list provided adjacent macropoint access (e.g., access points having high power). Here, the difference between the second and third groups may be used because the neighboring macropoint access may report the reduction of the large number of neighboring femto nodes, most of which can be located relatively far from the point 402 to access and, therefore, there is less likelihood that they would cause conflict with identifier control signal 402 used by the access point.

Continuing with the above example, in the case when one of the identifiers of the pilot signals from the assigned list is not used by any neighboring point 402 access (e.g., any of the identities of the first, second and third groups), point 402 access may simply select said ID pilot. Otherwise, if all identifiers of control signals from the assigned set are used, at least one of the neighbors, the point 402 access point may determine whether there is a conflict of any of the IDs of the control signals from the assigned set only to an access point from a third groups (i.e., no conflict with the first group or second group). If so, the access point 402 may select one of these identifiers control signals in an effort to minimize the risk of conflict. In the case where there is a conflict of all identifiers of control signals from the assigned list from any of the groups with the first group or the second group, the point 402 access point may select the identifier of the pilot signal, which interferes with only a group of two (in the case such an identifier of the pilot signal exists). In some embodiments, access point 402 is not permitted to select the identifier of the pilot signal from the first group. If there is a plurality of identifiers of the pilot signals of which should be made a choice, the access point 402 may select one of the identifiers of the pilot signals at random or in some other predetermined manner.

As shown by block 308, in which case access point 402 is configured such that it uses the selected identifier of the pilot signal for wireless communication. For example, the transmitter 410 may use the selected pilot identifier for generation of control signals broadcast which it produces.

As shown by block 310, the point 402 access may continue to current control ID of the control signals used by its neighbors (e.g., using the operations performed in block 304) to the access point could continue to ensure the absence of conflict is used by the identifier of the pilot signal with an ID the pilot used a neighbor. For example, this conflict can be caused by a new access point, which was recently installed near the 402 access or mobile access point, which came close to 402 access points. Besides conflict identifier of the pilot signal (e.g., a conflict situation) may occur if the two access points that are not within range of "hearing" each other, selected the same identifier of the pilot signal. Such a conflict can be eventually detected, for example, access terminal, which receives signals from both access points. In this case, one or both of these access points may be configured so as to change its control signal identifier. As described below with reference to FIG. 7, the access terminal detects a conflict that can report it to one or all relevant access points. For example, the access terminal can establish a connection with one of these access points for transmission of said information or may transmit this information to the appropriate access point using a compound which has an access terminal to another access point.

In the event that a conflict is detected, the access point 402 may perform operations analogous to those described above, for selecting a new identifier of the pilot signal, which does not conflict with any pilot identifier used any neighboring AP. Thus, by using these methods, the access point 402 may independently recover the control signaling conflicts of identifiers (e.g., conflicts associated with the identifier of the pilot signal). For example, upon receiving notice of a conflict or identifying a conflict of access point 402 can move its current identity of the pilot signal in a group of identifiers that are marked as forbidden (e.g., in the aforementioned first group) and repeat the operations described above.

In some cases, a change in its pilot identifier access point 402 may disable all compounds which it maintains the current time, and the force associated access terminals to re-establish the connection. As optimizing access point 402 may send an advance notification message to access terminal identifier of the new pilot and time point when the access point 402 switches to the new identifier of the pilot signal. Thus, switching to a new pilot identifier can be accomplished with minimal disruption of service.

Referring now to FIG. 5 and FIG. 6, the access point can detect its neighbors using neighbor discovery initiated by the access point and / or neighbor discovery by the access terminal. FIG. 5 shows an example of neighbor discovery initiated by the access point. FIG. 6 shows an example of detection of adjacent devices by the access terminal.

As shown in FIG. 5, the access point A can initiate the discovery of neighboring devices on obtaining information about the existence of a neighboring point B access. For example, as discussed above, the access point A can "hear" the information transmitted by way of broadcast radio neighbors (e.g. by using a downlink receiver), or to obtain information about its neighbors in any other way. As shown by block 502 in FIG. 5, the access point A can thus obtain information about the identifier (e.g., the address) of one of its neighbors.

Access Point A (for example, through the operations performed component is a controller discovery of neighboring devices) to establish a connection with the neighbor directly through backhaul messaging and perform the discovery of neighboring devices. For example, access point A requests a neighbor discovery unit ("SU discovery request") to the access point B. In response, the access point B (for example, through the operations performed component is a controller discovery of neighboring devices) sends a report on the discovery of neighboring devices ("report on the discovery of SU") at point A access. Similarly, the access point B sends a request to the detection of adjacent devices and the access point A in response to receiving a report on the detection of adjacent devices.

Preferably, the report from the access point B may include information about its neighbors (such as access point C). For example, information about the access point C may include information (e.g., id, address, etc.) sufficient to another node in the network can access the access point C. It should be understood that point C of access may be a nearby access point located at the distance of two-hop network (or more hop network) to point A to access (e.g., point A access can not "hear" the point C of access). In some embodiments, the access point B can automatically include in its report information on their neighbors. Alternatively, the access point A may issue a special request to ensure that the access point B to include this information in the report.

Therefore, point A access may use any information it receives from a neighbor at a distance of one hop network (for example, from point B to access) any neighbors within a few hops network to communicate with its neighbors in a radius of several transit sections of the network. For example, as shown in FIG. 5, the access point A sends a request for detection of adjacent devices and the access point C in response to receiving a report on the detection of adjacent devices. Similarly, the access point C sends a report on the discovery of neighboring devices in the access point A and in response to receiving a report about the discovery of neighboring devices. Like the above, the report on the detection of adjacent devices, sent from the access point C may include information about the neighbors (in FIG. 5 is not shown), the access point C. Thus, the access point A can receive information about their neighbors at a distance of three-hop network.

As shown in FIG. 6, the access point A to find out information about their neighbors by means of detection of neighboring devices by the access terminal. Here, the access terminal sends to its serving access point (a point A to access) a report on the control signals, which identifies all the control signals received by the access terminal (e.g., identifier ID2 pilot identifiers and other control signals). In the case where the identifier of the pilot signal in the record of control signals for a new access point A, the access point A, the access terminal may use to determine the addresses (e.g., IP-address) of a new access point. For example, the access point A can send a request for a sector identifier corresponding to the request (e.g., including an identifier of the pilot signal a new access point) to the access terminal. Then, the access terminal may send a response about the sector including the sector ID, the access terminal sends or any other appropriate response to the access point A.

Then, the access point A can carry out exchange of the detection results of neighboring devices with the new access point (e.g., access point B). As described above with reference to FIG. 5, point A access can receive information about the neighbors located at a distance of two-hop network (for example, point C is available) from point B to access, and then an exchange of the results of the detection of adjacent devices with a neighbor located (neighbors located) on a distance of two-hop network.

Referring now to FIG. 7 - FIG. 9, the inventive concept set forth herein is applicable to the configuration of the access point in the general case. For example, the methods described above and other methods described herein can be used to determine the set of configuration parameters for the access point. Examples of such configuration parameters are, inter alia, the frequency band carrier frequency, pilot identifier, the maximum transmission power and the transmission power profile, but these examples are not limiting feature.

As shown by block 702 of FIG. 7, the access point 802 (eg, the controller 846 detect neighboring devices) can determine the identity of its neighbors, but it is not a prerequisite. For example, like the above, the access point 802 may receive a list of neighbors from a configuration server (e.g., network node 804). Here, the operator can ensure its presence in the network of one or more centralized configuration servers assist in configuring the network access points. Once the access point 802 is initialized, it can initiate the configuration process.

In some aspects, the initialization of access point 802 includes receiving 802 the access point connectivity with a network operator. There may require authentication of the access point 802 before it is granted permission to access the network operator.

In addition, access point 802 can determine the location of the configuration server. For example, the access point 802 can be pre-configured with a known address (eg, IP-address) of the configuration server. Alternatively, the access point 802 may have information about the operator of the network to which it is connected (for example, operator.com), so the access point 802 may make a request to the Domain Name Service (DNS) on the fully qualified domain name (FQDN) "config_server. operator.com "and get back IP-address. In other embodiments, access point 802 may use any other method to obtain adequate information about the address. Access point 802 may then communicate with the configuration server. For example, communication can be established using a standardized simple network management protocol (SNMP) or other protocols configuration, such as, for example, NetConf, OMA DM, CWMP (TR 069) or DOCSIS, or using his own call level interface over a secure shell ( CLI over SSH).

As described above, the configuration server may provide a list of neighboring access point based on the location information, wherein the configuration server receives from an access point. These operations will be described in more detail with reference to the flowchart of FIG. 9 and to nodes 802 and network 804 of FIG. 8.

As shown by block 902 of FIG. 9, after initialization, the access point 802 location determination means 844 may determine the location of access point 802. Positioning means 844 can determine the position in various ways. For example, the position can be determined with the use of global positioning system ("GPS"), technology "assisted-GPS", the network position determination method, a radio frequency (RF) method or any other suitable method.

As shown by block 904, the access point 802 sends information relating to its location (e.g., an assessment of its location), a network node 804. In some embodiments, this operation may be initiated by the access point 802 (e.g., after the access point 802 establishes a connection with a configuration server). In some embodiments, the configuration server may issue a request for obtaining said location information explicitly as part of its connectionless protocol (e.g., by request). Access point 802 may send 804 the network node in other information (e.g., power profile, node type), which network node 804 may be used to provide an appropriate response.

As shown by block 906, after the network node 804 (e.g., means for determining the neighbors 840) receives location information from the access point 802, network node 804 identifies neighbor access point 802 and generates a list of neighbors. Said neighbor list may include, for example, any macropoint access, which are located relatively close to the access point 802, and any other access points (e.g., femto nodes, etc.) in the proximity of access point 802.

The list of neighbors may depend on the class power (or power profiles) 802 access point and its neighbors. For example, a neighbor of the access point 802 may be a remote access macropoint which transmits high power. In contrast, low power access point (e.g., femtouzel) located relatively close to the access point 802 may not be included in the neighbor list if a service area of ​​the access point and a low power access point 802 do not overlap. Consequently, in some cases the access point 802 may send the information about the class in the power network node 802 together with location information. Furthermore, the network node 804 may receive the power information from other access points in the network. As shown by the block 908, after the generated list of neighbors, the network node 804 sends a list of the neighbors mentioned in point 802 access.

Referring back to FIG. 7 as shown by block 704, the access point 802 (e.g., configuration controller 832) determines the configuration of its neighbors. As described above, the access point 802 may collect configuration information of its neighbors in various ways. For example, the access point 802 can connect directly to a neighbor across the backhaul and thereby assume the selected parameter set. Access point 802 can "hear" the air for one or more parameters of the neighboring access points (e.g., pilot identifier, as described above). Access point 802 can use the detection of adjacent devices by the access terminal, whereby the access terminal associated with the access point 802 may send configuration information to the access point 802. For example, the access terminal 818 (which is, for example, the controller configuration 836) can notify the access point 802 of the neighboring access points that are "heard" the access terminal 818. Moreover, as described herein, the access point 802 may obtain configuration information of neighboring nodes from the configuration server, for example, network node 804 (which is, for example, the controller 834 configuration). It will be appreciated that the access point 102 may receive configuration information using one or more of the methods described herein or by using other methods.

As shown by block 706, the access point 802 (e.g., configuration determining means 848) may define the configuration for the access point 802 based on the configuration information received at block 704. In some aspects, the access point 802 may autonomously select their own set of parameters (e.g. , radiofrequency (RF) parameters) depending on the parameters (e.g., RF parameters) its neighbors.

In some cases, the access point 802 may select a power profile based on power profile or profiles power of its neighbors. For example, the access point 802 may select the same power profile, which is used by its neighbors. Alternatively, the access point 802 may select a power profile that is complementary power profile used (power profiles used) his neighbor (neighbor). The power profile can be determined, for example, the maximum transmission power, the different transmission power values ​​for different conditions or other performance parameters.

As described above, in some cases the access point 802 may select an identifier of the pilot signal (e.g., pseudo-random noise sequence control signal (pilotPN)) based on the identifiers of the pilot signals used by its neighbors. For example, the access point 802 may select a pilot identifier than that of its neighbors.

In some cases the access point 802 may select a carrier (e.g., radio frequency band) based on the carrier used (carriers used) its neighbors. For example, adjacent nodes in the network can choose complementary sets priorities carriers (e.g., specified by the mask carrier, or any other appropriate pointers) to implement schemes combat interference. Here, each access point can emit more energy at some carriers, and less energy (e.g., does not emit or her) on the other carriers. If the neighboring access points are selected, these priorities bearing in a complementary manner, it can ensure that the access terminals associated with each access point may have more favorable operation in terms of interference of at least some of the carriers. To accomplish this offline new access point (e.g., access point, which has recently been initialized) can prioritize carriers used by its neighbors, and to prioritize their own carriers so that they are complementary to them as possible.

In some aspects, the configuration of the access point 802 may depend on its location. For example, the configuration server (which is, for example, the configuration controller 834) may specify a list (e.g., a subset) of the parameters (for example, the permissible range of parameter values) that can be used by the access point. As described above with reference to FIG. 3, a predetermined list may be based on the location of access point 802. For example, based on the location of access points 802 may be given a list of individual power profiles, which can be used to access point 802. Similarly, based on the location of access point 802 may be given a list of individual frequency bands that can be used by the access point 802. Massively city, state or country in which the current time point is 802 access may limit what what kind of bandwidth can use the access point 802. For example, one and the same operator may own different frequency bands in various countries, or the operator may designate the use of different frequency bands in different cities.

In some embodiments, configuration information may include optimizing certain parameters (e.g., parameters that do not belong to the radio). Such parameters may include, for example, security keys that may be used to access one or more services (e.g., network connectivity). Such parameters may also include the network addresses of other nodes with which the access point 802 may be required to establish a connection.

As shown by block 708 of FIG. 7, access point 802 may then use the configuration set at block 706 for communication, or for other operations. For example, as stated above, the transceiver 806 can be configured with a certain radio frequency (RF) parameters to determine which pilot identifier should be declared on which carriers need to work and what level of transmission power should be used on these carriers.

As shown by the block 710, the access point 802 may continue executing the current control configuration of their neighbors for conflict detection (eg, conflict). As mentioned above, in case of conflict, the access point 802 may perform the operations described above to eliminate configuration conflicts.

In some embodiments, access point 802 may receive a pointer of a conflict of access terminal (e.g., access terminal 818). For example, if the access terminal 818 detects a conflict (e.g., conflict detection means 838 detects the two access points use the same identifier of the pilot signal), then access terminal 818 may send a message 802 to the access point. Based on this message, the configuration controller 802 can perform the above operations to select a configuration for the access point 802.

It should be understood that the operations and components described above with reference to FIG. 7 - FIG. 9 may be applicable to circuit configuration described herein with reference to other drawings. For example, the operation and components can be applied to a configuration identifier of the pilot signal to an access point (e.g., as described above with reference to FIG. 3 - FIG. 6).

Referring now to FIG. 10 and FIG. 11, in some embodiments, the access point may receive configuration information from another node (e.g., from the configuration server), whereby configuration information depends on the location of the access point. For convenience, the operations shown in FIG. 10 and FIG. 11 will be described with reference to access point 802 to network node 804 from FIG. 8.

As shown by blocks 1002 and 1004 of FIG. 10, the access point 802 (e.g., positioning means 844) determines its location and provides this information to the network node 804. Thus, this operation may be similar positioning operations described above (e.g., in blocks 902 and 904).

As shown by the block 1006, unit 804 network (for example, configuration of the controller 834) determines the configuration information for the access point 802 based on the received location information. For example, as described above, the configuration information may comprise radio frequency (RF) parameters optimization parameters, the other parameters or a combination of two or more of these parameters. In some cases, this operation could lead to an entirely new configuration task for 802 access points. In an alternative embodiment, network node 804 may define only part of the parameters used by access point 802.

As shown by block 1008, the network node 804 sends configuration information 802 to the access point. In this case, the access point 802 is configured to use the received configuration information (block 1010).

Referring now to FIG. 11, in some cases, the configuration server can decide to redirect the access point in a configuration server. Such a decision can be made, for example, based on the location of the access point and / or load the configuration server.

As shown by the block 1102, the access point 802 to the node 804 sends a message to the network configuration information. As described above, this message may include information indicating a location of access point 802.

As shown by the block 1104, unit 804 network (for example, a means of selecting the configuration server 842) may determine whether to provide the requested information on the configuration. For example, network node 804 may determine, based on the location of access point 802, that said request is to be processed by another configuration server (e.g., closer to the access point 802). Moreover, the network node 804 may decide to redirect the request based on the load of the network node 804. For example, if the node 804 network is heavily loaded, the network node 804 may forward the request to another server configuration, which is not so heavily loaded.

As shown by blocks 1106 and 1108 in the case where the network node 804 decides to handle the request, the network node 804 may provide the requested configuration information to the access point 802. For example, this operation may be similar to the operations described above with reference to FIG. 10.

As demonstrated by the 1110, if the node 804, the network decides that he will not perform the processing of the request (for example, on the basis of its load or proximity point 802 access), the node 804 network (for example, the means 842 select the configuration server) indicates another configuration server that can provide configuration information to the access point 802. For this purpose the network node 804 may store a database that contains information about other servers in the network configuration. Additionally or alternatively, network node 804 may be configured to perform the detection of another node or to establish communication with the node to receive said information.

As shown by block 1112, the network node 804 sends an indication of another configuration server in the access point 802 (e.g., a redirect message). In some embodiments, the said Index may contain information that allows the access point 802 to determine the address of the other server configuration. For example, the said Index may contain location data (eg, city) server configuration. Upon receipt of the above information access point 802 may determine the address of the other server configuration (for example, by querying in the Domain Name Service (DNS)).

In some embodiments, said pointer contains the address of another configuration of the server. In some embodiments, the redirection may be implemented as follows: the configuration server sets a parameter that specifies the address of a configuration server. In determining whether a change in this parameter, the access point 802 attempts to establish a connection with a new configuration server.

As shown by the block 1114, the access point 802 may thus send a message to a different configuration server for configuration information. Once the access point 802 completes its exchange of information on the configuration with the configuration server, the access point 802 can start the operation due to the subscribers.

As mentioned above, the idea of ​​the invention set forth herein may be implemented in a network, which utilizes macropoint access femto nodes, relay nodes, etc. FIG. 12 and FIG. 13 illustrate examples how access points may be deployed in such a network. FIG. 12 simplistically illustrates how the cell 1202 (e.g., macrocells 1202A-1202G) system 1200 may be served by a wireless communication corresponding access point 1204 (e.g., 1204A-1204G points of access). Here, macro 1202 may correspond to the macro zones 204 service from FIG. 2. As shown in FIG. 12, access terminals 1206 (e.g., access terminals 1206A - 1206L access) may be dispersed at various locations throughout the system over time. Each terminal 1206 to access may communicate with one or a large number of points 1204 to access the forward link ("FL") and / or a reverse link ("RL") at a particular time depending on, for example, whether access terminal 1206 is active and whether it is in soft handoff communication control (soft handover). By using the honeycomb structure of said circuit system 1200 can provide wireless communication service in a large geographic area. For example, each of the macrocells 1202A-1202G may cover a number of neighboring blocks or several square miles in rural areas.

FIG. 13 illustrates an example of how one or more femto nodes may be deployed in a network environment (e.g., system 1200). The system 1300 of Fig. 13, a plurality of femto nodes 1310 (e.g., femto nodes 1310A and 1310B) placed in a network environment with a relatively small area of ​​the service area (e.g., in one or more places of residence 1330 subscribers). Each femtouzel 1310 may be connected to a wide area network 1340 (e.g., the Internet) and the core network 1350 mobile operator (including, for example, disclosed herein hosts) via a router digital subscriber line (DSL), cable modem, a wireless connection or other means of connecting to a network (not shown).

Owner femto nodes 1310 may subscribe to mobile service, such as, for example, mobile services third-generation (3G), proposed in 1350 by a core network of mobile operator. In addition, an access terminal 1320 may be capable of operating both in macro environment and network environment in an area with a smaller coverage areas (e.g., homes). In other words, depending on the current location of the terminal 1320 to access terminal 1320 to access can be served by point 1360 to access the macro cell associated with the base network 1350 mobile operator, or by any of a set of femto nodes 1310 (e.g., femto nodes 1310A and 1310B, which are in a suitable position 1330 Unknown subscriber). For example, when a subscriber is outside his home, said subscriber may be served by a standard macropoint access (for example, point 1360 access) and when the subscriber is outside his home, or in it, said subscriber may be served by femto nodes (eg, node 1310A network) . There femtouzel 1310 may provide backward compatibility with the access terminals 1320 legacy.

Femtouzel 1310 may operate on the same frequency or, alternatively, on multiple frequencies. Depending on the particular configuration of the single frequency or one or more of the multiple frequencies may overlap with one or a large number of frequencies used macropoint access (e.g., access point 1360).

In some aspects, the access terminal 1320 may be configured to connect to a preferred femto nodes (e.g., femto nodes with the home access terminal 1320) whenever there is a possibility of such a compound. For example, whenever the access terminal 1320A is in the place of residence of the called party in 1330, it may be desired that the access terminal 1320A communicate only with supporting home femto nodes 1310A and 1310B.

In some aspects, if the terminal 1320 to access operating in the macro network 1350 cellular, but not in the most preferred for a network (which, for example, defined in the list of preferred roaming), the terminal 1320 to access may continue to search for the most preferred network (e.g., the preferred femto nodes 1310) using the function better system reselection ("BSR"), which may involve a periodic scanning of available systems to determine whether better systems at the current time, and subsequent attempts to joining such preferred systems. By inputting the collected information to access terminal 1320 may limit the search for specific band and channel. For example, a search for the most preferred system may be repeated periodically. Upon detection of a preferred femto nodes 1310, the access terminal 1320 selects femtouzel 1310 for temporary stay within its service area.

On femtouzel may be restricted in some aspects. For example, a particular femtouzel may only provide certain services to certain access terminals. The deployed systems with so-called limited (or closed) association of a particular access terminal may only be served by the mobile communication network with a given set of macro and femto nodes (eg, femto nodes 1310 that are within the respective 1330 place of residence of the subscriber). In some embodiments, at a network node can be imposed such restrictions that it does not provide the at least one network node, at least one of the following functions: signaling, data access, registration, paging, or service.

In some aspects femtouzel with restrictions (which may also be called a home NodeB Node closed subscriber group) represents such femtouzel that provides service to a limited set of access terminals provided. If necessary, said set can be extended on a temporary or on a permanent basis. In some aspects, the Closed User Group ("CSG") may be defined as the set of access points (eg, femto nodes) that share a common list of access terminals for access control. The channel, which employs all femto nodes (or all restricted femto nodes from) the territory, may be cited femtokanalom.

Consequently, there can be different relationships between the specific femto nodes and a particular access terminal. For example, from the perspective of an access terminal concept "open femtouzel" may refer to a femto nodes without limited association (e.g. femtouzel allows access to any access terminal). The term "femtouzel with restrictions" may refer to a femto nodes, which imposed some restrictions (such as having restrictions on association and / or registration). The concept of "home femtouzel" may refer to a femto nodes that can be accessed and the work which allowed the access terminal (eg, granted permanent access to a given set of one or more access terminals). The term "guest femtouzel" may refer to a femto nodes that can be accessed and the work which temporarily allowed the access terminal. The concept of "foreign femtouzel" may refer to a femto nodes that can be accessed and the work with which the access terminal is not allowed, except for perhaps emergency situations (for example, telephone calls to the number 911).

From the viewpoint of femto nodes constrained term "home access terminal" may refer to an access terminal is authorized to access the restricted femto nodes with (e.g., access terminal has permanent access to the femto nodes). The term "guest access terminal" can refer to an access terminal with temporary access to femto nodes with restrictions (such as having a limit deadline, time of use, bytes, or the number of connections on the basis of some other criterion or criteria). The concept of "alien access terminal" can refer to an access terminal is not allowed to access the femto nodes with restrictions, with the exception, perhaps, of emergencies, such as, for example, calls to 911 (for example, an access terminal that does not have the powers or permission for registration in the femto nodes with restrictions).

For convenience, the essence of the invention disclosed herein various functionalities described with respect to femto nodes. However, it should be understood that pikouzel or relay node may provide the same or similar functionality for a different (e.g., larger) coverage area. For example, pikouzel or relay node may be restrictions for konkretnog of the access terminal can be set pikouzel home or home relay node, etc.

Idea of ​​the invention presented here can be implemented in any type of communication devices. In some aspects, the idea of ​​the invention set forth herein may be implemented in wireless devices that may be deployed in a communication system with multiple access, which can simultaneously support communication for multiple wireless access terminals. Here, each terminal may communicate with one or with more access points via transmissions on the straight lines and feedback. The term "forward link" (also known as downlink) refers to the communication link from the access points to the terminals, and the term "reverse link" (also known as uplink) refers to the communication link from the terminals to the access point. This communication link can be established by means of "single-input single-output" system "multiple-input multiple-output" ("MIMO") system or any other type.

For illustrative purposes in FIG. 14 shows a typical connection means, which can be used in a wireless communication system 800 applied to a multiple-input multiple-output (MIMO). The system 1400 for transmitting data using multiple (T) transmit antennas and multiple () reception antennas. A multiple-input multiple-output (MIMO), formed by the transmission antennas and reception antennas may be decomposed into independent channels, which are also referred to as spatial channels, where. Each of the independent channels corresponds to a dimension. A multi-input multi-output (MIMO) may provide improved performance (e.g., higher throughput and / or greater reliability) if the additional dimensionalities created by the multiple transmit and receive antennas.

System 1400 may provide support for duplex time division ("TDD") and duplex frequency division ("FDD"). In duplex communication system with time division (TDD) transmission lines by forward and reverse links are in the same frequency region so that the reciprocity principle allows the estimation of parameters of a forward link channel in the parameters of the reverse link. This enables the access point to extract gain due to the transmission beamforming on the forward link when multiple antennas available at the access point.

System 1400 includes a wireless device 1410 (e.g., access point) and a wireless device 1450 (e.g., access terminal). The 1410 data for a number of data streams is fed from the storage device 1412 in data transmission 1414 treatment ("TX") data.

In some aspects, each data stream is transmitted over a respective transmit antenna. Apparatus TX data processor 1414 formats, codes, and interleaves the traffic data for each data stream based on a particular coding scheme selected for that data stream to create coded data.

The coded data for each data stream may be multiplexed with pilot data using the methods of multiplexing, orthogonal frequency division (OFDM). The pilot data is typically a known data pattern, the processing which is performed in a known manner and may be used at the receiver system to estimate the channel parameters. Subjected multiplexed pilot and coded data for each data stream is then modulated (i.e., put to the symbol) based on a particular modulation scheme (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M -PSK) or M-QAM (M-QAM)), selected for that data stream, creating the modulation symbols. The data rate, type of coding and modulation for each data stream can be specified by instructions performed by processor 1430. The memory 1432 can store data for the code, data, and other information that are used by the processor 1430 or other components of the device 1410.

The modulation symbols for all data streams are then fed to a device 1420 for processing transmission in MIMO mode, which may perform further processing of the modulation symbols (e.g., for an orthogonal frequency division (OFDM)). Then, processing unit 1420 for transmission in the MIMO mode delivers a modulation symbol streams transceiver ("XCVR") 1422A-1422T. In some aspects, apparatus 1420 for processing transmission in MIMO mode applies beamforming weights to the symbols of the antenna data streams and to the antenna from which the symbol transmission.

Each transceiver 1422 receives a corresponding symbol stream, and performs its processing, creating one or more analog signals, and further executes the formation (e.g., amplifies, filters, and upconverts) the analog signals to create a modulated signal suitable for transmission channel multiple-input multiple-output (MIMO). Then, the modulated signals from transceivers 1422A-1422T is transmitted from the respective antennas 1424A - 1424T.

In the device 1450, the transmitted modulated signals are received by antennas 1452A-1452R, and the received signal from each antenna 1452 is applied to a transceiver ("XCVR") 1454A-1454R. Each transceiver 1454 performs formation (e.g., filters, amplifies, and downconverts) a respective received signal, converts the conditioned signal into digital form, creating a sample, and performs further processing of the samples, creating a corresponding stream "received" symbol.

<IMG>

Then, processing unit 1460 accepted ("RX") data receives and processes the received symbol streams from transceivers 1454 based on a particular receiver processing techniques, creating flows of "detected" symbol. Then, processing unit 1460 demodulates the received data, deinterleaving, and decoding each detected symbol stream restoring traffic data for the data stream. The processing performed by the processing device 1460 received data is the complementary processing performed by the processing device 1420 for transmission in the MIMO mode and the device 1414 transmission data processing unit 1410.

A processor 1470 periodically determines which pre-coding matrix to use (this is discussed below). Processor 1470 formulates a message to be transmitted on the reverse link, which comprises a portion representing the index of the matrix and a portion representing the value of the rank. In memory of the 1472 data may be stored program code, data and other information that are used by the processor 1470 or other components of the device 1450.

The message to be transmitted on the reverse link may comprise various types of information regarding the communication link and / or the received data stream. The message to be transmitted on the reverse link, and then treated by the device 1438 TX data processor which also receives traffic data for a number of data streams from the storage 1436, modulated by a modulator 1480 operate signal shaping by the transceivers 1454A-1454R, and transmitted back to the 1410.

In 1410, the modulated signals from the device 1450 are received by antennas 1424 operate signal shaping by transceivers 1422, demodulation by a demodulator ("DEMOD") 1440, and processed by the processing device 1442 for extracting received data messages transmitted on the reverse link device 1450.

Processor 1430 then determines which pre-coding matrix to use for determining the beamforming weights of the antenna, and thereafter performs processing the extracted message.

FIG. 14 also illustrates that the communication means may comprise one or more components that perform configuration control operations ("CONFIG.") According to the inventive concept presented here. For example, a configuration management component 1490 may cooperate with the processor 1430 and / or other components of the device 1410 to send / receive signals to another device / from another device (which is, for example, device 1450) in accordance with the inventive concept described herein. Similarly, a configuration control component 1492 may cooperate with the processor 1470 and / or other components of the device 1450 to send / receive signals to another device / from another device (which is, for example, 1410). It will be appreciated that for each device 1410 and 1450 the functionality of two or more components described herein can be provided by a single component. For example, a single processing component may provide the functionality of the configuration control component 1490 and the processor 1430 and a single processing component may provide the functionality of the configuration control component 1492 and the processor 1470.

A CDMA network may implement a radio technology such as Universal Terrestrial System Radio Access ("UTRA)", technology cdma2000 standard, or some other technology. System UTRA includes W-CDMA technology and technology Low Chip Rate ("LCR") (low chip rate signal). Technology cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a radio technology such as Global System for Mobile Communications ("GSM"). In OFDMA network may implement a radio technology such as Evolved Universal Terrestrial System Radio Access (Evolved UTRA ("E-UTRA")), IEEE 802.11, IEEE 802.16, IEEE 802.20, Flash-OFDM® etc . System UTRA, E-UTRA and the Global System for Mobile Communications (GSM) is part of a Universal Mobile Telecommunications System ("UMTS"). Idea of ​​the invention presented here can be implemented in the standard "Long Term Evolution" ("LTE") communication systems of the third generation (3GPP), in the Ultra Mobile Broadband (Ultra-Mobile Broadband ("UMB")) and in systems of other types. The system is a version of the LTE standard UMTS, which uses E-UTRA. Despite the fact that certain aspects of the disclosure, the invention may be described using the terminology of 3GPP, it should be understood that the foregoing is the idea of ​​the invention can be applied to technologies 3GPP Release (Rel99, Rel5, Rel6, Rel7), as well as technology 3GPP2 (IxRTT , 1xEV-DO RelO, RevA, RevB) and other technologies.

Idea of ​​the invention presented here can be implemented in a variety of devices (e.g., nodes) (e.g., implemented in, or performed by them). In some aspects, the network node (e.g., node wireless network) implemented in accordance with the inventive concept described herein may comprise an access point or access terminal.

For example, the access terminal may comprise, be implemented as, or may be known as user equipment, a subscriber station, subscriber unit, mobile station, mobile device, mobile node, a remote station, remote terminal, user terminal, user agent, user device or referred to by some other terminology. In some embodiments, the access terminal may comprise a cellular telephone, mobile phone wireless phone, based on a Session Initiation Protocol ("SIP"), a wireless local loop ("WLL"), personal digital assistant ("PDA" ), a handheld device having wireless connection capability, or some other suitable processing device connected to a wireless modem. Accordingly, one or more aspects set forth herein of the invention can be implemented in the mobile phone (e.g., a cellular phone or smart phone), a computer (e.g., a laptop), a portable communication device, a portable computing device (e.g., a private information device), a device for entertainment (e.g., a music device, a video device, or a satellite radio), a global positioning system device location or any other suitable device configured to communicate via wireless communication means.

Such an access node may provide, for example, connectivity for or to a network (e.g., WAN, which is, for example, the Internet or a cellular network) via a wired channel or a wireless communication network. Accordingly, an access node may provide another network node (e.g., access terminal) to access the network or some other functionality. Furthermore, it should be understood that one or both of the nodes may be portable or, in some cases, relatively non-portable.

It should also be appreciated that a wireless node may be able to perform transmission and / or receiving information in a manner that is not wireless (e.g., via a wired connection). Thus, a receiver and a transmitter, which are considered herein may include appropriate communication interface components (e.g., electrical or optical interface components) to communicate via a means that is not wireless.

The wireless communication device may provide support to one or more of the plurality of wireless communication technologies, protocols, or standards such as those discussed herein (e.g., CDMA, TDMA, OFDM, OFDMA, WiMAX, Wi-Fi, etc.), or otherwise their use. Similarly, a wireless node may provide support for one or more of the plurality of corresponding modulation or multiplexing schemes, or used otherwise. Consequently, the wireless network node may include appropriate components (e.g., radio interfaces) to establish and communicate via one or more channels through the wireless communication using the above or other wireless communication technologies. For example, a wireless node may comprise a wireless transceiver with respective transmitter and receiver components that may include various components (e.g., signal generators and signal processing apparatus) that facilitate communication over a wireless communication means.
