Abstract: Performing uplink reception by a base station (BS) in a wireless communication system. In some implementations, a method includes: transmitting configuration information for a first sounding reference signal (SRS) that specifies a relation between the first SRS and a second SRS that is a reference for spatial beamforming of the first SRS, and based on the configuration information, receiving the first SRS which is transmitted by applying, to the first SRS, a first spatial beamforming that is identical to a second spatial beamforming used for transmission of the second SRS. The method further includes transmitting downlink control information (DCI) for uplink scheduling, where the DCI includes a SRS resource indication (SRI) and where a SRI field in the DCI carries the SRI, and where a bit width of the SRI field is based on a number of SRS resources in an SRS resource set configured for a user equipment (UE).

Abstract: A method for reporting channel state information of a terminal comprises: a step of measuring CSI-RS transmitted from a base station; and a step of reporting CSI generated on the basis of the CSI-RS measurement to the base station, wherein the CSI comprises: a PMI for indicating a precoding matrix from a codebook and an RI for indicating a rank, wherein the PMI comprises a first PMI for a beam group selected by the terminal and a second PMI which comprises a beam sub-group selection information for beams included in the beam group and phase-matching information for each antenna port polarization for the selected beam sub-group, and wherein as the rank increases, the phase-matching information may be indicated with different granularity from each other depending on whether the beam sub-groups selected from the beam group are the same or different.

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.
