Abstract: Methods, systems, and devices are described for wireless communication at a device. A transmitting device such as a base station may select some packets for direct transmission to a receiving device using data compression based on the reliability of the direct connection. The transmitting device may select other packets for indirect transmission via an unreliable connection using uncompressed packets or compressed packets that will not be used to update a compression buffer. In some cases, uncompressed packets may also be sent via the reliable connection. If a packet sent over the unreliable connection is lost, it may be transmitted over the reliable connection.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE) capable of establishing a split bearer involving at least primary and secondary radio link control (RLC) entities. The techniques generally include deciding, based on one or more conditions, whether to submit a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU) to the primary RLC entity or the secondary RLC entity according to one or more rules and submitting the PDCP PDU to at least one of the primary or secondary RLC entities in accordance with the decision.

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: Session initiation messages may be compressed using templates for evolved data compression scheme (eDCS). One or more session initiation messages may be exchanged between various network entities, such as UEs and base stations, for purposes such as registration, call setup, and call modification, for example. Session initiation messages may include header fields which identify the caller and characteristics of the device receiving the call, and may also contain payload, which describes the audio/video codec characteristics. Many of these contents may be repeated across all user devices of the same vendor attached to the same operator and may be compressed using templates to enhance system efficiency. These templates may be known at the transmitter and receiver, and reduce the data that has to be carried over air.

Abstract translation: 可以使用用于演进数据压缩方案（eDCS）的模板来压缩会话发起消息。 例如，可以在各种网络实体（例如UE和基站）之间交换一个或多个会话发起消息，例如注册，呼叫建立和呼叫修改。 会话发起消息可以包括标识呼叫者的头部字段和接收呼叫的设备的特性，并且还可以包含描述音频/视频编解码器特性的有效载荷。 这些内容中的许多可以在连接到相同操作者的同一供应商的所有用户设备上重复，并且可以使用模板来压缩以提高系统效率。 这些模板在发射机和接收机处可能是已知的，并减少必须在空中传输的数据。

Abstract: A method of communication performed by a base station (105) as well as a base station (105) are described. The method comprising receiving (1705) a buffer status report, BSR, comprising a first content size indicating an amount of data packets currently stored in an uncompressed buffer (205) of a user equipment, UE (115), receiving (1710) a compressed data packet from the UE (115), determining (1715) a compression gain by computing a ratio of a size of the compressed data packet and a size of a corresponding uncompressed data packet, adjusting (1720) the received BSR based at least in part on the compression gain and assigning (1725) a grant to the UE (115) based at least in part on the adjusted BSR.
