1. A method of transmitting channel state information (CSI) in a wireless communication system, the method performed by a terminal comprising:
receiving, from a base station, configuration information related to the CSI;
receiving, from the base station, one or more RS (reference signal) resources transmitted by a different downlink spatial domain transmission filter; and
transmitting, to the base station, the CSI including a L1-SINR (Layer 1 Signal-to-Interference-plus-Noise Ratio) generated based on the one or more RS resources,
wherein the configuration information includes information on M (M is a natural number) RS resource groups,
wherein each of the M RS resource groups includes one or more RS resource pairs configured with an RS resource for channel measurement and an RS resource for interference measurement,
wherein the CSI includes information on N (N≤M, N is the natural number) RS resource groups selected from the M RS resource groups and a L1-SINR value for the N RS resource groups.
