    摘要: Certain aspects of the present disclosure provide a method for bearer count alignment during handover of a user equipment (UE) from a first radio access technology (RAT) to a second RAT. The UE establishes radio resource control (RRC) connections with the second RAT and transmits data radio bearer (DRB) capability of the UE to the second network. The second network utilizes this information to set up the DRBs with the UE.

    摘要: Systems and methodologies are described that facilitate identifying a plurality of keysets utilized in a communications network. The keysets can include ciphering keys that provide data encryption and decryption and integrity keys that provide data integrity protection. A key identifier can be included in a packet data convergence protocol header that indicates a keyset employed in connection with data in a protocol data unit. In addition, a route indicator can be provided in a radio link control header that distinguishes a source cell and a target cell in networks configured without RLC reset.

    摘要: The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network, or any cellular network, and a packet-switched network. During hand-over from the first network to the second network, the sender of packets/frames expands or compresses the packet-switched packets using well-known time-warping techniques. At the receiver end, the received time-warped packets and frames from the second network are appropriately selected so that no unwanted artifacts are introduced during playback.

    摘要: The method and apparatus as described are directed toward techniques and mechanisms to improve efficiency in wireless communication networks through optimization of handover scenarios. Determining whether an intra-base station or inter-node-B handover is to be performed, and determining the protocol layers to reset during the handover based at least in part on the type of handover to be performed increases the overall efficiency of the wireless network.

    摘要: Systems and methodologies are described that facilitate communicating a Buffer Status Report (BSR) from user equipment (UE) while reducing the employment of a RACH procedure. A BSR Prohibit time interval can be triggered by a receipt of uplink data to the UE. The BSR can be conveyed utilizing an uplink-shared channel (UL-SCH) if a Scheduling Request (SR) or a Semi-Persistent Scheduling (SPS) occurs within the duration of the BSR Prohibit time interval. The BSR can be communicated utilizing a RACH procedure if a SR or SPS occurs upon the expiration of the BSR Prohibit time interval.

    摘要: A wireless terminal concurrently associates with multiple wireless local area networks. The wireless terminal may operate in power save mode on both of the WLANs to prevent a disruption of communication on either WLAN. The wireless terminal may adjust the times at which it listens for beacons to enable reception of beacon information even though the beacons for different WLANs may overlap in time. Beacon transmission times also may be scheduled to avoid overlapping transmissions of beacons on different WLANs.

    摘要: The disclosure is directed to an apparatus and method for encoder initialization and communications. The apparatus may include a database and an encoder module. The database may be configured to receive a plurality of parameters to be used for operation of the encoder module. The database may be further configured to store the plurality of parameters and to provide the plurality of parameters to the encoder module. The encoder module includes an encoder configured to be initialized based on the plurality of parameters from the database. When invoked, the encoder may rely on the database to initialize rather than performing measurements on the current signal that is to be encoded. In one aspect, the apparatus may be an access terminal that can seamlessly switch between different domains, different networks, different base stations, and different access points.

    摘要: Techniques to support beamforming for stations in a wireless network are described. A station may support beamforming with implicit or explicit feedback by having capabilities to transmit and receive sounding frames, responding to training request by sending a sounding frame, and responding to request for explicit feedback. In one explicit beamforming embodiment, the station may send a first frame with an explicit feedback request and may also send a Null Data Packet (NDP) having at least one training field but no data field. The station may receive a second frame with explicit feedback, which may be derived based on the NDP. The station may derive steering information based on explicit feedback and may then send a steered frame with beamforming based on the steering information. Other aspects, embodiments, and features are also claimed and described.
