METHOD FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION PERIODICALLY OR APERIODICALLY

摘要

A method for periodically/non-periodically transceiving CHI(Channel State Information) is provided to solve a problem for PUSCH(Physical Uplink Shared Channel) capacity when a terminal periodically transmits the CHI. A pointer for requesting a CHI report for a downlink channel is received from a base station through a downlink control channel(S401). The CHI is non-periodically transmitted to the base station by using a PUSCH according to pointer reception(S402).
