METHOD AND SYSTEM FOR COORDINATED COMMUNICATION, ACCESS NETWORK DEVICE, AND USER EQUIPMENT

摘要

Provided in embodiments of the present invention are a method and system for coordinated communication, an access network device, and a user equipment (UE). The method comprises: when the access network device receives downlink data belonging to a first UE, if a supporting UE in a support list of the first UE is determined as being incapable of serving as the current supporting UE of the downlink data, then establishing a coordinated communication relation between a second UE and the first UE, that is, setting the second UE as the current supporting UE of the first UE, where the second UE is a UE other than the first UE and the supporting UE in the support list of the first UE; transmitting the downlink data to the second UE, thus allowing the second UE to transmit the downlink data to the first UE. This increases the reliability of data transmission for the first UE.
