    摘要： A method is performed by a terminal in a wireless communication system. The method comprises receiving, from a base station, a radio resource control, RRC, message for configuring a plurality of non-zero power, NZP, channel state information reference signal, CSI-RS, resources. Receiving, from the base station, a medium access control, MAC, control element, CE, for selecting at least one NZP CSI-RS resource among the plurality of NZP CSI-RS resources. Receiving, from the base station, downlink control information, DCI, including channel state information, CSI, request field associated with one NZP CSI-RS resource among the at least one NZP CSI-RS resource. The method further comprises transmitting, to the terminal, an aperiodic CSI report including CSI parameters obtained based on an aperiodic CSI-RS corresponding to the one NZP CSI-RS resource.
