Abstract: Methods, systems, and devices are described for wireless communication at a UE. In aspects, a receiver may receive a transmission requesting information about support for data compression. The receiver may determine parameters related to the types of supported data compression and communicate the information to the transmitting device. In some cases, the receiver may then receive a message from the transmitting entity that requests establishment of a data compression configuration. The receiver may respond with confirmation or rejection of the proposed compression configuration. If the configuration is confirmed, the transmitter and receiver may exchange compressed data packets according to the configuration. The devices may exchange status and control information related to the compression configuration (e.g., in a compression header of a compressed message or a separate status and/or control information message).

Abstract: A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.

Abstract: Aspects of the present disclosure provide methods, systems, devices and/or apparatuses for logical channel prioritization by a user equipment (UE) within a Long Term Evolution (LTE) wireless communications network. The UE may have multiple logical channels each associated with one or more applications or services of the UE. The UE may identify whether a quality of service (QoS) obligation to allocate at least a portion of uplink resources to a logical channel for a time period is present, and may also identify whether the logical channel has control data to be transmitted from the UE. If a QoS obligation and/or control data are present for the logical channel, the UE may allocate at least a portion of the uplink resources to the logical channel.

Abstract: 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.

Abstract: An apparatus for wireless communication includes a processing system. The processing system is configured to perform a first set of functions in a first thread. The first set of functions includes obtaining second data from a second thread and providing first data to the second thread to facilitate construction of an uplink packet in the second thread. The processing system is further configured to perform a second set of functions in the second thread. The second set of functions includes obtaining the first data, constructing the uplink packet based on the first data, and providing the second data to the first thread to facilitate the performing of the first set of functions.

Abstract: 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.
