    摘要: A method for efficiently transmitting and receiving feedback information is disclosed. A cluster size as a unit for computing the feedback information and a reporting period of the feedback information are not uniformly determined by a base station. Information about a downlink channel status of each user equipment is reported, the cluster size and feedback period for computing and reporting the feedback information are determined using the information about the downlink channel status of each user equipment, and the feedback information is transmitted/received, thereby improving system capability.
