Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/172903
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for transmitting and receiving channel state information in a wireless communication system. A method for transmitting channel state information (CSI) according to one embodiment of the present disclosure may comprise the steps of: receiving configuration information related to the CSI from a base station; receiving one or more reference signal (RS) resources transmitted from the base station through different downlink spatial domain transmission filters; and transmitting, to the base station, the CSI including a layer 1 signal-to-interference-plus-noise ratio (L1-SINR) generated on the basis of the one or more RS resources. The configuration information includes information about M (M is a natural number) RS resource groups, each of the M RS resource groups includes one or more RS resource pairs consisting of an RS resource for channel measurement and an RS resource for interference measurement, and the CSI may include information about N (N≤M, N is a natural number) RS resource groups selected from the M RS resource groups and L1-SINR values for the N RS resource groups.
