Abstract: A system to control paging cycles in a wireless network assigns mobile stations to one of a plurality of paging groups based on the paging cycle requirements of the individual mobile stations. In addition, the mobile stations in a particular paging group are further subdivided into subgroups that may be substantially equal in size. At any particular paging cycle, only one subgroup of a particular paging group is included in the paging process thus reducing the overall number of mobile stations that need to be paged in any particular paging cycle.

Abstract: Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.

Abstract: Systems and methods of uplink bandwidth allocation for a handoff are provided. A mobile station can transmit a handoff request message to a serving base station. The mobile station and the target base station can exchange synchronization messages and the mobile station can then subsequently receive an unsolicited allocation of a number of uplink sub-channels from the base station.

Abstract: A method of assigning parameter values to transceivers in a wireless communication network. Each of the parameter values assigned determines at least in part how a plurality of subcarriers are organized into a plurality of sub-channels. In particular embodiments, the method assigns the parameter values to the transceivers based on correlations between the sub-channels determined by the parameter values, distances between the transceivers, and loads experienced by the transceivers. After the parameter values are assigned to the transceivers, each of the transceivers is configured to transmit on the sub-channels determined at least in part by the parameter value assigned to the transceiver.

Abstract: Methods and systems for performing hybrid automatic repeat request (ARQ) in conjunction with broadcast/multicast channels are presented. In particular, an access node may transmit a series of hybrid ARQ subpackets to one or more client nodes using a broadcast/multicast channel. Each of the subpackets may be derived from the same full packet. Upon receiving a subpacket, a client node may attempt to decode the full packet from the subpacket(s) derived from the full packet. If the client node fails to do so, the client node may transmit a negative acknowledgement to the access node. If the access node receives more than a threshold extent of negative acknowledgements, the access node may transmit a subsequent subpacket in the series on the broadcast/multicast channel.

Abstract: Methods and systems for assigning time-division multiplexed (TDM) slots in a multi-channel TDM system are presented. Preferably, a radio access network (RAN) assigns forward link and reverse link transmissions between the RAN and one or more wireless communication devices (WCDs) to TDM slots on various wireless channels. When making these assignments, the RAN may take into account (i) the priority of data that the RAN queues for the WCDs, and (ii) the signal quality at which the WCDs can receive the various wireless channels.

Abstract: A method and computer-readable medium for dynamic rate capping of data transmissions of a subscriber are provided. According to the method, configuration parameters for dynamic rate capping are defined. A plurality of subscriber parameters are obtained, and a plurality of network parameters are measured. A rate boost factor is calculated based on a backhaul rate boost factor and a sector rate boost factor. A transmission rate cap for subscriber data transmissions is calculated based on backhaul and sector parameters, such as backhaul and sector rate boost factors. The rate of subscriber data transmissions is dynamically controlled based on the transmission rate cap.

An endpoint receiving packets with non-voice information transmits negative and positive acknowledgements over a dedicated channel in an uplink subframe. When the endpoint receives packets with voice information, the endpoint transmits negative acknowledgements over a shared channel, but does not transmit positive acknowledgements.

Abstract: A method is disclosed that can be carried out in an access network comprising a plurality of coverage areas, each coverage area being served by an RNC. The method involves making a determination that an access terminal is located in an inter-RNC boundary zone, and then, during a communication session: (i) determining that a handoff from a source coverage area to a target coverage area should be performed; (ii) determining whether or not the target coverage area is served by the same RNC as the source coverage area; (iii) if the target coverage area is not served by the same RNC as the source coverage area, delaying handoff until a current segment of the communication session is complete; and (iv) if the target coverage area is served by the same RNC, handing off the communication session to the target coverage area.

Abstract: Systems and methods of setting up a push-to-talk call are provided. When a push-to-talk server receives a request for a push-to-talk call from an originating mobile station, the server sends a push-to-talk call notification to a destination mobile station identified in the request and starts a timer. Upon expiration of the timer the server determines whether the originating mobile station has a traffic channel for the push-to-talk call.
