    摘要: Embodiments of the present invention provide a method and a device for transmitting downlink data in multiple UEs cooperative communication. A base station selects a benefitted user equipment UE, where the benefitted UE and a supporting UE are UEs in a closed cooperative group, each data radio bearer of each UE in the cooperative group corresponds to a logical channel identifier LCID, and the LCID is unique in the cooperative group; the base station generates a media access control packet data unit MAC PDU, where the MAC PDU comprises data to be sent by a data radio bearer of the benefitted UE, and a LCID corresponding to the data radio bearer, and the base station sends the MAC PDU to the supporting UE. The above solutions achieve a method of multiple UEs cooperative communication for synthesizing on the MAC layer.

    摘要: 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.
