BACKGROUND Wireless communication systems are widely deployed to provide various types of wireless content, such as, for example, voice content, data content, and the like. Typical wireless communication systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multiple-access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, etc. may include

In general, wireless multiple-access communication systems are capable of simultaneously supporting communication for a plurality of mobile devices. Each mobile device may communicate with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from base stations to mobile devices, and the reverse link (or uplink) refers to the communication link from mobile devices to base stations. Further, communications between mobile devices and base stations may be via single-input single-output (SISO) systems, multiple-input single-output (MISO) systems, multiple-input multiple-output (MIMO) systems, and the like. can be set.

One function of mobile network technologies that facilitate convenient device mobility is the idle/active mode of mobile devices. When active, the mobile device may process incoming signals, send response signals, and facilitate remote voice and/or data communication with other devices . However, these activities can consume a significant amount of power which reduces the battery life of the mobile device. Fortunately, the average user only periodically intervenes in active device communication. Accordingly, significant power may be conserved by not processing received wireless signals during periods of non-use. Limited or unprocessed periods are called idle periods.

To receive an inbound communication, a mobile device (eg, when another user calls the mobile device) is required to process signals indicating that such communication is ongoing for the mobile device. In the case of an idle state, however, the device either processes very few signals or does not process signals, and thus will miss communication unless active long enough to process these signals. To facilitate active/idle mobility, the base station serving the mobile device coordinates the periods of time during which the mobile device is active to process incoming signals. These periods of time may be short or relatively infrequent to reduce average mobile device processing and power consumption in idle mode. When an inbound communication for a mobile device is received at the base station, the paging signal is scheduled and transmitted at one or more coordinated periods of time that the mobile device monitors (eg, activates and processes the signals). By manipulating intermittent periods of active signal processing, the mobile device can identify and receive inbound communications while conserving significant processing power and battery life. This design provides significant utility to the average mobile device user, increasing device mobility and overall convenience of mobile communication.

This specification provides the establishment of paging controls for mobile devices connected to an orthogonal frequency division multiple access (OFDMA) radio access network (AN). Setting the paging controls may include dividing the wireless signal into a number of time frames determined from a constant power of an integer (eg, 2^K, where K is a constant). Also, paging opportunities may be scheduled as part of the time frames of the radio signal. The selection of time frames of paging opportunities may be based on a formula using an integer raised to a power that is a function of a constant. The selected paging opportunities may be grouped within a discontinuous reception (DRX) cycle of a radio signal, or distributed over a subset of time frames based on the formula above. Also, one or more paging groups may be assigned to each of the paging opportunities.

Various aspects are now described in connection with the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, various specific detailed descriptions are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspect(s) may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more aspects.

In addition, various aspects of the present disclosure are described below. It is evident that the teachings herein may be embodied in a wide variety of forms and that any specific structure and/or function disclosed herein is representative only. Based on the teachings herein, one of ordinary skill in the art should recognize that an aspect disclosed herein may be implemented independently of any other aspects and that two or more aspects may be combined in various ways. do. For example, an apparatus may be implemented and/or a method practiced using any number of the aspects set forth herein. Further, an apparatus may be implemented and/or a method practiced using other structure and/or functionality in addition to or different from one or more aspects described herein. By way of example, many of the methods, devices, systems and apparatus described herein are set forth in the context of establishing device-specific and system wide paging controls for a mobile communication environment. Those of ordinary skill in the art should recognize that similar techniques may be applied to other communication environments.

Disclosed content is a mobile environment (eg, universal mobile telecommunications system (UMTS), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA)), frequency division multiplex (FDM), evolved UMTS terrestrial (E-UTRAN) radio access network), and/or similar mobile access networks). In particular, it is provided for hashing user devices into parts of a wireless signal to affect paging. Because many user devices can be served by a single network access point at a given time, paging for user devices is performed on multiple separate portions (eg, resources) of the wireless signal. Each user device may be assigned a separate signal resource and may monitor this resource for paging signals. False alarm pages can be avoided where fewer devices than available paging resources are served by the access point (eg, multiple devices are paging as a result of an inbound call to only one of the paged devices). if so). If more user devices are served than the available paging resources, a plurality of devices may be allocated to one or more of these individual portions, if necessary. This can lead to false alarm paging, and is only for devices that are allocated to a single paging resource. Accordingly, the disclosed subject matter provides for avoiding or mitigating aspects of false alarm paging in FDM, FDMA, OFDMA, and/or similar mobile environments.

In accordance with some aspects herein, radio signal paging resources are defined as multiple time and/or identity based portions of a radio signal. For example, the signal may be divided into a plurality of time-based paging opportunities. The paging opportunities may include a time frame of a discontinuous reception (DRX) cycle of a signal. In accordance with some aspects, a paging opportunity may include a portion of a time frame, or a plurality of time frames. In addition to the preceding description, a plurality of paging groups may be provided for a wireless signal. The paging group may be distinguished based on the identity of the mobile device (eg, International Mobile Subscriber Identity (IMSI), or similar identifier). Thus, ten unique IMSIs assigned to ten devices may be used to create ten separate paging groups for these devices. Paging groups may be used to differentiate paging controls for each device. A paging group provided in this manner may be named either a paging group identity or a paging indication radio network identifier (PI-RNTI).

As described above, the use of paging groups may limit the time domain occupancy of paging resources. However, if the paging group identity may be transmitted using L1/L2 control channels (eg in an OFDMA system), and thus the paging group identity is taken from a common identity space, the identity may also be a scarce resource. have. Also, if the mobile network allows a plurality of paging groups to be paged in one L1/L2 control signaling, the size of available PI-RNTIs may be relatively limited. Also, distribution of paging signals in different time frames may help avoid concentrated uplink (UL) interference. For example, if multiple devices are paged in a single time frame of a downlink (DL) signal, these devices will typically initiate a random access procedure in a common UL time frame that coincides with the DL time frame. This may result in interference in the UL time frame. UL interference is mitigated when paging is distributed over the various DL time frames. Accordingly, in at least one aspect of the subject matter herein, the identity and time-based resources of the wireless signal are used in combination in a controllable manner. As an example, the paging identity space may be controlled via L3 protocols by signaling the range of PI-RNTIs used for paging a group indication.

For time-based paging opportunities, the number of frames (eg, sub-frames and groups of frames) used for paging may be limited. As an example, an identity and time-based paging system may include 'N' time-based paging opportunity resources and 'M' identity-based paging groups, where 'N' and 'M' are integers. The values of 'M' and 'N' may be system parameters broadcast in a wireless signal using system information (eg, control channel information). The hashing function used to assign mobile devices to a paging group and/or paging opportunity (eg, based on the user's IMSI) may also be broadcast in the system information. In accordance with certain aspects of the subject matter herein, the selection of paging resources (eg, paging opportunities and/or paging groups) is in a formula comprising an integer raised to a constant power. can be based In at least one aspect, the integer may be two, which results in a power of two formula. In at least one other aspect, the power may be a constant associated with a DRX cycle of the wireless signal. By using constant powers of integers (eg, the power of 2 formula), paging can be made more compatible with other systems. Accordingly, a mobile device entering a cell served by an OFDMA access point may be aggregated with paging resources, as described in more detail below.

As disclosed above, selected time-based signal resources used for paging may be scheduled on portions of the wireless signal in different ways. As an example, selected time-based portions may be grouped into consecutive portions of the DRX cycle of the radio signal. The location, length, number, etc. of the partitions of the contiguous part may be broadcast together with the system information. After obtaining the system information, the mobile device(s) can interpret the paging resources and identify the resource allocated to paging signals for it. In other aspects, time-based paging resources may be selected from the wireless signal using a power of two formula. These resources may be distributed throughout the DRX cycle, depending, for example, on the particular formula used, the constant values of this formula, and the like. The location of the distributed time-based paging resources may also be broadcast in system information to indicate to mobile devices how to translate paging signals.

Although it is beneficial to hash users across paging groups and paging opportunities to reduce the occurrence of false alarm paging, cell-wide paging can also be beneficial. For example, when system information pertaining to all mobile devices in a cell is updated, paging all these devices on a single paging resource (or, for example, a small number of paging resources) may It can be an efficient way to distribute. In some systems, dedicated system-wide resources are not essential (eg, code division multiple access (CDMA) or wideband CDMA, where the paging indicator channel(s) may use one or more bits for system wide paging). (WCDMA)). For E-UTRAN or similar systems, where PI-RNTIs are transmitted over an L1/L2 control channel, it is not always feasible to dedicate system-wide resources. In general, the subject matter of this specification provides for system wide paging (eg, a 'paging all devices' resource), using a special PI-RNTI, or paging a group resource. In accordance with this alternative, it is not necessary to page all paging groups and paging opportunities to convey system wide information. Instead, the user device may be configured to recognize a particular PI-RNTI, in addition to a dedicated or semi-dedicated PI-RNTI. Thus, the user device may process signals in all PI-RNTIs, which may include device-specific paging information as well as system-wide paging information.

3 shows a block diagram of an example system 300 that provides paging controls for wireless communication in a mobile operating environment. System 300 includes a paging device 302 coupled to an access point 306 (eg, a base station) in a mobile operating environment. The access point 306 facilitates wireless communication for one or more mobile devices 304 . For example, the access point 306 may be connected to a data network (e.g., the Internet, a private intranet, etc.) that facilitates data communication with remote devices (e.g., data storage, data server, application server, etc.); mobile device 304 using a voice network (eg, a mobile telephone network, a public switched telephone network, a voice over internet protocol (VoIP) network, not shown) that facilitates voice communication with remote devices, as well as ) can be connected to

When the mobile device 304 is actively engaged in data and/or voice communications, general communications and processing functions are utilized in the device 304 to facilitate such communications, as is known in the art (eg, , see FIG. 8 , described below). When not actively engaged in data and/or voice communications, the mobile device 304 may enter an idle state for a significant period of time to reduce device processing and associated power consumption. When idle, very little information transmitted by the access point 306 is processed by the mobile device 304 . However, to identify inbound calls, device 304 may monitor a subset of wireless signals transmitted by access point 306 to page signals belonging to mobile device 304 . An adjustment may be made by the paging apparatus 302 as to which subset of signals include paging signals, and thus which subset of signals the mobile device 304 should monitor.

In accordance with at least some aspects of the present disclosure, the paging apparatus 302 includes a timing module 308 that divides the wireless signal 316 transmitted by the access point 306 into at least a plurality of signal time frames. can do. The signal time frames may be repeated periodically for a plurality of DRX cycles of the wireless signal 316 , for example. Each signal time frame includes synchronization information (e.g., synchronization pilot signal, primary synchronization sequence (PSS), secondary synchronization sequence (SSS)), control channel information, paging information, traffic data, and/or the like. , can be used to convey different information. The subset of signal time frames of the wireless signal 316 , determined by the selection module 310 , are to the mobile devices 304 served by the access point 306 (see, eg, FIG. 6 , described below). for paging control information. Each time frame containing paging control information may be named a paging opportunity. The selection module 310 may determine paging opportunities from the available time frames of the wireless signal 316 by using various selection formulas.

In at least one aspect of the subject matter herein, the timing module 308 is configured to control the rate of the wireless signal 316 per cycle (eg, a DRX cycle, signal superframe, etc. suitable for the network architecture implemented in the access point 306 ). A formula involving a constant power of an integer (eg, Int^K, where Int is an integer and K is a constant) can be used to determine the number of time frames (Z). In such aspects, the selection module 310 may use an integer and/or a different formula based on the constant to determine the number N of paging opportunities from the Z time frames.

The location of the paging opportunities in the wireless signal 316 may be determined from formulas used by the selection module 310 to select the paging opportunities. Optionally, the location of the paging opportunities may be a default location. In one aspect of the subject matter herein, locations may be grouped into consecutive portions of wireless signal 316 (see, eg, system 600A, described below). In another aspect, locations may be distributed throughout the wireless signal, as determined by a selection formula that selects paging opportunities (see, eg, system 600B of FIG. 6 , described below). It should be appreciated that the number, location, length, etc. of paging opportunities, as well as a particular paging opportunity/paging group belonging to the mobile device 304 may be transmitted to the mobile device 304 .

The paging device 302 may further include a transmit processor 312 . The transmit processor 312 may implement various wireless communications for the access point 306 . In an aspect, the transmit processor 312 may schedule the control channel information into the wireless signal 316 . Control channel information may specify system information, including identifying paging resources (eg, paging opportunities/paging groups) of wireless signal 316 . In at least one aspect, the transmit processor 312 may identify a particular paging resource allocated to the mobile device 304 . Such a resource may be determined from established paging resources based on a selection algorithm using the identifier of the mobile device 304 . The identifier may be, for example, a mobile subscriber identity (MSI), an IMSI, a data session identifier (eg, a mobile network data address, an Internet Protocol (IP) address, etc.), or by the mobile network serving the mobile device 304 . the identifier being specified, or similar identifier(s), or a combination thereof. In accordance with at least one aspect of this disclosure, the transmit processor 312 may select a paging resource for the mobile device 304 based on the following formula:

Paging opportunity = (IMSI div L) mod N, where N is the total number of paging opportunities of wireless signal 316 . The allocation of paging resources to mobile devices 304 associated with the access point 306 as well as associated identifiers of the mobile devices 304 may be stored in the memory 314 . The assignment may be maintained as a list that may be broadcast to mobile devices 304 associated with the access point 306 , for example. In some aspects, an allocation of paging resource(s) to a mobile device 304 may be determined and unicast to such device 304 .

In some aspects, the paging apparatus 400 may couple with a base station (not shown) of a wireless AN (eg, E-UTRAN) to provide paging controls for the base station. In other aspects, the paging apparatus 400 may be coupled with a central controller (eg, see FIG. 1 , described above, at 130 ) to provide paging controls for a plurality of base stations of the wireless AN. The paging controls provided by the paging apparatus 400 include one or more services served by the wireless AN's access point(s), as well as the signal resource(s) shared by all such devices for broadcasting system information. may include paging resources dedicated to mobile devices. Accordingly, the page apparatus 400 may facilitate a low power idle mode for mobile devices by coordinating paging resources with the devices, as described herein and known in the art.

The paging apparatus 400 may include a timing module 402 that divides a wireless signal transmitted by an access point of a wireless AN into a plurality of time frames. In some aspects herein, a number of such time frames per signal, or per DRX cycle, is, for example, a constant power of an integer (eg, 2) (eg, the constant is a DRX cycle of the wireless signal). determined from). The paging apparatus 400 may further include a selection module 404 for selecting a plurality of paging opportunities used to transmit paging signals to one or more mobile devices. The number of paging opportunities, N, is a subset of the number of time frames and may be selected as described herein.

The paging apparatus 400 may further include an allocation module 406 that may group the paging opportunities into successive portions of the wireless signal. The continuous portion may be repeated for each DRX cycle of the radio signal. As an example, the allocation module 406 assigns N numbers of selected DRX cycles, periodic DRX cycles, and the first N time frames of each DRX cycle (or, for example, other suitable contiguous portion) of the radio signal. Paging opportunities can be scheduled.

Optionally, in addition to the preceding description, the paging device 400 may include a calculation module 408 . Calculation module 408 calculates a distributed arrangement of paging opportunities based on a formula using an integer constant (eg, DRX cycle count, number of frames in a cycle, cycle length, or other suitable constant) power, Int. (as opposed to a contiguous arrangement, for example) can be determined. In some aspects, the integer may be the same integer used by the timing module 402 to define the signal time frames (or DRX cycle) of the wireless signal. According to certain aspects, the integer may be 2 and the constant may be a DRX cycle constant.

As a specific, non-limiting example of the preceding description, the calculation module 408 may select and/or arrange the N paging opportunities by using a formula of the form: Frame number mod Int^K <= N-1 where frame number is an identifier of a particular frame (eg, a frame in sequential order relative to other frames), and Int is the number of time frames of radio signal 316 . An integer used by the timing module 402 to determine (Z), and K is the DRX cycle constant. In at least one aspect of the present disclosure, Int=2, so the cycles of the wireless signal 316 include 2^K time frames and the paging opportunities are determined from the formula: Frame number mod 2^K <= N-1. As an optional example to the preceding description, paging opportunities may be determined from the formula: Frame number mod Int^(KL) = 0. Thus, in aspects where Int=2, paging opportunities are determined based on frame number mod 2^(KL) = 0. It should be appreciated that various formulas may be used by the calculation module 408 to arrange paging opportunities in place of or in addition to the example formulas above. Accordingly, the foregoing formulas should not be construed as limiting the content of the invention to the specific form expressly expressed herein. Rather, a similar mechanism for selecting paging opportunities known to those of ordinary skill in the art or known in the art by way of example of background provided in the context of this specification is incorporated herein.

In addition to the preceding description, the calculation module 408 may assign paging opportunities to mobile devices served by the access point, and vice versa. The assignment of paging opportunities may be based on the identifier of the mobile devices. For example, a unique IMSI may be used to determine a paging opportunity for a particular mobile device. In one example, an algorithm in the form of (IMSI div L) mod N may be used by the calculation module 408 to select paging opportunities for mobile devices. However, other suitable examples exist for allocating a paging opportunity to a mobile device; As examples of the background provided herein, such examples known in the art or to those of ordinary skill in the art are incorporated herein by reference.

The paging device 400 may further include a grouping module 410 . The grouping module 410 may provide paging groups (PI-RNTIs) for radio signals of a mobile network (eg, E-UTRAN, OFDMA, etc.). Paging groups may be provided based at least in part on identifiers of mobile devices assigned to a paging opportunity. For example, paging groups of a common paging opportunity may be distinguished (eg, by the calculation module 408 ) by using individual mobile device identifiers of the devices assigned to the paging opportunity. Accordingly, grouping group 410 may further partition time-based paging resources into identity-based paging resources. Such partitioning may increase the number of individual resources (eg, a plurality of resources allocated to a single paging resource) suitable for sending paging signals to mobile devices and reducing the moments of paging false alarms in these devices. resulting from devices).

In addition to the above description, the paging device 400 may include a broadcast module 412 . The broadcast module 412 is configured to facilitate system-wide paging using minimal signal resources. In some aspects, the broadcast module 412 may generate a common identity for all remote devices in a cell served by the wireless access point. The common identity may be associated with the selected PI-RNTI resource(s) of the radio signal. Also, the selected PI-RNTI(s) may be distributed in the system control information as a paging channel for all mobile devices in the cell. The mobile device may thus monitor the selected PI-RNTI as well as the dedicated PI-RNTI(s) assigned to the mobile device by the computation module 408 , as described above. Accordingly, system information may be obtained through the selected PI-RNTI, and device-specific information (eg, inbound calls) may be obtained through dedicated PI-RNTI(s).

The paging device 402 may further include a processor 414 and a memory 416 . The processor 414 may be configured to disseminate the paging control information to the mobile devices served by the access point, or access points of the wireless AN. The paging control information may be broadcast in combination with synchronization data, control channel data, and the like. The information may include a list of paging resources (eg, paging opportunities and/or PI-RNTIs) used by the access point, the location of these resources in the wireless signal, and similar information. The information includes other associated data, such as algorithms used to determine time frames of a wireless signal, select paging opportunities, and assign paging opportunities to devices, or generate PI-RNTIs, as described herein; and or stored in memory 416 along with mobile device identifiers used to assign devices to signal resources. Accordingly, paging apparatus 400 may, in some aspects of the subject matter herein, include a paging system suitable for implementing, disseminating, and maintaining system paging for OFDMA, E-UTRAN, or similar mobile communication networks. have.

Array 500 may include 'N' paging opportunities and 'M' paging groups (eg, PI-RNTIs). As described herein, paging opportunities may include time-based portions of a wireless signal, such as time frames. As described herein, paging groups may include identity-based portions of paging portions. The paging resource coincides with the paging opportunity/paging group intersection block of the array 500 . Thus, array 500 includes 'M' X 'N' paging resources, and thus substantially provides 'M' X 'N' individual paging resources for 'M' X 'N' mobile devices. can do. In some aspects of the present disclosure, at least one paging resource may be reserved for broadcast paging of system information for all devices served by a particular cell.

To distinguish the 'M' paging groups for each paging opportunity, a mobile device identifier 506 may be assigned to each resource block of the paging resource array 500 . Thus, an IMSI, MSI, IP address, medium access control (MAC) address, or other suitable identifier of a mobile device may be used to differentiate paging group resources, and these identifiers (eg, no other device is the same Any other device that is globally unique to devices (eg served by a given mobile network and connected with a given access point) or is globally unique to devices (so that they do not have the same identifier in the context) at a given point in time is unique to devices locally, such as not to have the same identifier in . For a paging resource reserved for cell-wide broadcast paging signals, a common identifier may be allocated by the network component as the reserved paging resource and provided to each device in the cell. Thus, these devices are able to identify system-wide paging, at least in part, using a common identifier.

According to additional aspects herein, the allocation of paging resources may be provided to mobile devices in a DL signal. In one example, the paging assignment of all resources may be broadcast to all devices. The broadcast may further specify an algorithm for identifying the allocated paging resource based on the identifier (eg, IMSI) of the receiving devices. Accordingly, in such aspects, mobile devices may use an algorithm to identify which paging resource(s) to monitor for inbound communications. The broadcast may also identify system-wide paging resources to be monitored and processed by all devices in the cell. Alternatively or additionally, the access point may send a unicast message to the mobile device specifying the paging resource(s) and location(s) of such resource(s) associated with the device. In such aspects, the mobile device may simply receive the paging resource information and monitor the specified resources to obtain an indication of the inbound communication.

Distributions 600A, 600B illustrate optional mechanisms for allocating/selecting determined paging opportunities as described herein. In a first distribution 600A, paging opportunities are grouped into at least one contiguous portion of the wireless signal. The portion may be repeated in multiple DRX cycles of the wireless signal, and may select DRX cycles. In certain aspects herein, the number of time frames (N) of the signal used for paging opportunities may be determined based on a power of two algorithm (eg, N=2^L). Once determined, the paging opportunities are grouped into one or more consecutive portions of the DRX cycle. In at least one aspect of the subject matter herein, the following formula may be used to determine the number and/or location of grouped paging opportunities in a wireless signal: Frame number mod 2^K <= N-1.

The location of the contiguous portion(s) may be transmitted to remote devices using broadcast messaging, unicast messaging, a combination thereof, or the like. Further, the continuous portion(s) may be included in a single cycle of the radio signal, included periodically in a plurality of cycles, included in an optional plurality of cycles, and modulated into a plurality of cycles.

Distribution 600B shows a distributed arrangement of paging opportunities. The plurality of N paging opportunities may be selected based on a power of two algorithm. A power of two algorithm may be used, for example, to select specific time portions of a wireless signal for paging resources. In certain aspects, the base integer 2 in the algorithm may be raised to a constant (K) power, where K is determined from the length of the DRX cycle of the wireless signal (eg, based on the number of total time frames 2^K) do. According to at least one aspect, the following formula may be used to determine the distributed paging opportunities: (1) Frame number mod 2^(KL) = 0. The paging opportunities may be distributed throughout the DRX cycle of the wireless signal based on the frame number of the selected paging opportunities.

Distribution arrangements 600A, 600B may be submitted to a mobile device that is coupled with an access point of a wireless AN. In addition, devices may submit appropriate, access point identifier information that may be used to provide paging resources. By sharing the distribution information, a mobile device can determine which paging resources are allocated to that device. Accordingly, the mobile device may enter an idle mode when it is not participating in active voice or data communications and is substantially monitoring only paging opportunities of a wireless signal related to the mobile device.

The communication processor 812 may further include a signal processor 812 for obtaining the paging group assigned to the identifier submitted by the communication processor(s) 812 . In some aspects, a paging group may be associated with a paging opportunity selected from a subset of signal time frames of a DL signal.

In addition to the preceding description, the signal processor 812 may obtain the location of a paging group and/or paging opportunity within the DL signal. The signal processor 812 may also monitor the paging group/time to facilitate identifying paging signals for the mobile terminal 802 . In some aspects, the location of the paging group/viewpoint may be part of a continuous portion of the DL signal reserved for paging resources. In other aspects, the paging group/time may be a distributed identity/time based on a portion of this signal. The paging response module 816 may extract information from the paging group/viewpoint and determine whether a paging signal is included therein.

At 1014 , the method 1000 may distribute the set of paging opportunities across one or more signal time frames of the wireless signal as determined by a power of two formula. For example, a formula may be used to select which DRX cycle's signal time frames are assigned to paging opportunities. Method 1000 may proceed from 1014 to 1016 .

At 1016 , the method 1000 may allocate a plurality of paging groups for the determined paging opportunities.

Registration may include, for example, submitting at least an identifier (eg, IMSI) of the mobile device to the wireless AN. At 1104 , the method 1100 can obtain the paging group assigned to the identifier. The paging group may, in at least one example, be determined based on an identifier of the mobile device and a number of available paging groups for the wireless signal. In one particular example, the paging group may be obtained from an algorithm such as IMSI mode M, where M is the number of available paging groups. The paging group may be submitted over a DL channel and may be received by the antenna(s) and receiver at the mobile device.

13 shows a block diagram of a sample system 1300 that facilitates paging controls in an OFDMA wireless AN. System 1300 can include a module 1302 for registering for wireless communication. For example, the registration may be for a mobile communication network via a wireless access point connected to such a network. In some aspects, module 1302 may include an identifier of the mobile device in connection with registration, where the identifier is a global identifier (eg, IMSI, MAC address), or a semi-global or local identifier (eg, a semi-global or local identifier). eg IP address, MSI, data session identifier, etc.). Additionally, system 1300 can include a module 1304 for obtaining a paging group as an example of wireless communication. Further, a paging group may be associated with an identifier by an access point of a wireless AN (eg, E-UTRAN). In at least one aspect, a paging group may be associated with a paging opportunity selected from a subset of signal time frames of a DL signal. The selection of a paging opportunity from the signal time frames may, in at least one example, be based on a formula comprising a constant power of an integer (eg, the number 2). The position of the paging group in the DL signal can be obtained from this signal, either directly or indirectly by using formulas and identifiers.
