METHOD, TERMINAL, AND BASE STATION FOR TRANSMITTING AND RECEIVING CHANNEL INFORMATION

摘要

The present invention relates to a wireless communication system which uses multiple-input multiple-output (MIMO) antennas for both transmitting and receiving ends. In particular, the technical features are characterized by a step for receiving feedback from at least one terminal at a base station on a first channel state information and a second channel state information at intervals different from each other; and a step for receiving feedback, when the terminal and at least one other terminal are simultaneously allowed to connect, on multiple-access information on the other terminal from among the first channel state information and the second channel state information which has the shorter interval but which is longer than one interval.
