    • Systems and methodologies are described that facilitate providing user plane support for internet protocol (IP) relays. Service data units (SDU) received at a radio communication layer can be provided to an upper communication layer, such as a packet data convergence protocol (PDCP) layer, without regard to sequence numbers. The upper communication layer can handle reordering of the received protocol data units. Since communications related to a plurality of devices through one or more IP relays can be mapped over a single bearer, allowing reordering at the upper communication layer can mitigate delay caused where a donor or other upstream access point is delayed in providing a sequential SDU related to one of a plurality of devices downstream. In this regard, SDUs related to other devices can be processed by the upper communication layer while waiting for the sequential SDU.
    • 描述了有助于为互联网协议(IP)中继提供用户平面支持的系统和方法。 在无线电通信层接收的服务数据单元(SDU)可以被提供给诸如分组数据会聚协议(PDCP)层的上层通信层,而不考虑序列号。 上层通信层可以处理接收的协议数据单元的重新排序。 由于可以通过一个或多个IP中继器与多个设备相关的通信可以通过单个承载进行映射,所以允许在较高通信层重新排序可以减轻在供体或其它上游接入点被延迟的时候引起的延迟,以提供与 下游的多个设备中的一个。 在这方面,与其他设备相关的SDU可以由上层通信层处理,同时等待顺序SDU。
