    摘要: Systems and methodologies are described herein that facilitate efficient handling of packets (e.g., Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) or Service Data Units (SDUs)) in a wireless communication system. As described herein, a number of consecutive packets that are discarded due to a discard timer expiration event and/or other causes can be monitored and compared to a number of tolerated consecutive discarded packets. If the number of consecutive discarded packets does not exceed the number of tolerated consecutive packets, conventional processing operations such as header modification and compression, ciphering, or the like can be omitted for respective packets subsequent to a discarded packet, thereby significantly reducing processing overhead. As further described herein, the number of tolerated consecutive discarded packets can be chosen to maintain header compression (e.g., Robust Header Compression (RoHC)) synchronization, ciphering synchronization, and/or other suitable properties.

    摘要: Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.

    摘要: Devices and methods are provided for expedited recovery from radio link failure or the like. In one embodiment, the method involves collecting at least one optional system information block (SIB) during connected mode, wherein the at least one optional SIB comprising neighbor information. In another embodiment, the method involves storing dedicated information provided by a base station through a dedicated channel. The method generally involves using the neighbor information and/or dedicated information for cell selection, in response to the radio link failure.

    摘要: Systems and methodologies are described that facilitate formation and/or dispatch of radio link control (RLC) protocol status reports to a base station. The system can include components that quantify an absence of protocol data units, ascertain whether a number of absent protocol data units exceeds the size of a transmission side grant, insert a sequence number associated with a first absent protocol data unit into an acknowledgement sequence number field associated with a partial status report, incorporates the sequence number associated with the first absent protocol data unit in the partial status report, includes sequence numbers of subsequent absent protocol data units into the partial status report without exceeding the transmission side grant, and sends the partial status report to the base station.
