摘要： The present disclosure provides a method for triggering aperiodic Channel State Information (CSI ) feedback used in a multiple coordinated cells multiple component carriers system. According to the present disclosure, a base station firstly semi-statically configures a user equipment to CoMP transmission modes, and/or information on measurement cells, and/or information on measurement component carriers by a high layer signaling (RRC signaling). Then, the base station dynamically initiates an aperiodic CSI feedback request to the user equipment by downlink control information (through PDCCH). When receiving the aperiodic CSI feedback request transmitted by the base station, the user equipment transmits measured aperiodic CSI to the base station through an uplink channel (PUSCH or PUCCH). According to the present invention, the method for triggering aperiodic CSI feedback in CoMP transmission modes can be flexibly configured, and good backward compatibility can be obtained at the same time. The above method is simple and effective, the system design complexity is low, and the design requirements for practical systems and LTE-Advanced evolved systems are met.
