Patent ID: 10931361

Abstract:
The present specification provides a method for transmitting and receiving channel state information (CSI) in a wireless communication system.More specifically, a method performed by a user equipment (UE) includes receiving a resource block from a base station based on a first spatial Quasi-Co location (QCL) related parameter related to reception of the resource block including at least one control channel, wherein when the resource block and the CSI-RS are configured on the same symbol, the first spatial QCL related parameter and a second spatial QCL related parameter configured for reception of the CSI-RS are equally configured; configuring a beam for receiving the CSI-RS based on the second spatial QCL related parameter; and receiving the CSI-RS from the base station through the configured beam.The present specification has an effect that a UE, in which a less number of Rx chains are implemented, can receive multiple CSI-RSs.
