Abstract: 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.

Abstract: In a method for accessing a legacy wireless network, a radio access network (RAN) node in the legacy wireless network receives an access message sent by a User Equipment (UE) attempting to access the legacy wireless network. The access message includes mobility management entity (MME) information identifying an MME accessed by the UE in an evolved network. The MME information is added by the UE from a temporary identity (ID) allocated by the MME to a first P-Temporary Mobile Station Identity (P-TMSI) in the access message. The RAN node selects a corresponding Serving GPRS Support Node (SGSN) in the legacy wireless network for the UE according to the first P-TMSI in the access message.

Abstract: The present invention discloses a multiple users cooperative communication (MUCC) method and system. The main idea of the present invention is as follows: through multiple users cooperative communication between APs, data to be sent to a UE by an eNB may be sent to a support AP at first, and then the support AP sends the data to the UE; and when the support AP is in a poor network environment, the eNB may send the data to other APs near the support AP, and finally forward the data to the support AP through one or more times of forwarding between other APs. The present invention has a multiuser diversity gain without increasing the complexity and power consumption of the UE; furthermore, a laying cost of wired backhaul can be reduced and reliability and transmission efficiency of MUCC can be improved.
