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: A method and apparatus for prioritizing data packets when stateful compression is enabled for wireless communications is disclosed. For example, the aspects include receiving a plurality of data packets scheduled in a first order for transmission. The described aspects further include prioritizing one or more data packets of the plurality of data packets as one or more prioritized data packets, each prioritized data packet being scheduled in an order for transmission different from the first order for transmission. The described aspects further include compressing one or more unprioritized data packets of the plurality of data packets into one or more compressed unprioritized data packets. The described aspects further include scheduling the one or more prioritized data packets and the one or more compressed unprioritized data packets in a second order for transmission, the second order differing from the first order.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to enhanced compression formats for data compression (e.g., uplink data compression (UDC)). A method is provided for wireless communications. The method generally includes determining one or more blocks of data in a current packet matching one or more blocks of data in one or more portions of one or more previous packets stored in a memory, compressing at least a portion of the current packet based on an enhanced compression format having reduced metadata relative to another compression format to indicate one or more of the matching blocks of data, and transmitting the compressed current packet. Numerous other aspects are provided.
