数据传输方法及装置
摘要：
提供了一种数据发送方法，所述方法包括：将多个用户设备UE对应的媒体接入控制MAC载荷封装在一个MAC分组数据单元PDU中，其中，所述MAC PDU包括包头、所述MAC载荷以及所述多个UE中各个UE的标识信息；所述包头包括多个子包头，所述多个子包头为所述多个UE中每个UE对应的MAC载荷分别对应的子包头，所述每个UE对应的MAC载荷包括MAC控制单元CE和/或MAC服务数据单元SDU，所述标识信息用于标识所述各个UE；以及发送所述MAC PDU。相应地，还提供了数据接收方法和装置。上述方案中，通过发送封装有多个UE对应的数据的MAC PDU，并在该MAC PDU中包含各UE的标识信息，实现了在多用户协同通信中传输MAC PDU。
摘要（英）：

A data sending method is provided. Media access control MAC payloads corresponding to a plurality of user equipment (UEs) are encapsulated in one MAC packet data unit PDU, where the MAC PDU includes a header, the MAC payloads and identification information of each UE in the plurality of UEs; and the header includes a plurality of subheaders, the plurality of subheaders is subheaders respectively corresponding to a MAC payload corresponding to each UE in the plurality of UEs, the MAC payload corresponding to each UE includes a MAC control element CE and/or a MAC service data unit SDU, and the identification information is used for identifying each UE. The MAC PDU is sent. Correspondingly, a data receiving method and apparatus are also provided. In the foregoing solutions, transmission of a MAC PDU during multi-user cooperated communication is implemented.
