主权项

1. A method for determining, by a base station, cooperative devices of client cooperation in a wireless communication system, the client cooperation helping a source device communicating with the base station through a cooperative device, the method comprising:
selecting the cooperative device among candidate cooperative devices if at least one of a number of activation trigger conditions is satisfied; and indicating client cooperation is to be activated or a connection establishment procedure with the selected cooperative device to a candidate source device is to be performed, wherein the activation trigger conditions include:
a difference between a first quality and a second quality is equal to or greater than a first offset,a third quality is greater than a threshold, anda difference between the third quality and the second quality is equal to or greater than a second offset, wherein the first quality is a quality of a direct link between the base station and the candidate cooperative devices, wherein the second quality is a quality of a direct link between the base station and the candidate source device, and wherein the third quality is a quality of an indirect link between the base station and the candidate source device through the candidate cooperative devices.
