Document Type and Number:
WIPO Patent Application WO/2021/225325
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for reporting a channel state of a user equipment in a wireless communication system. The method may comprise the steps of: receiving, from a base station, configuration information for measurement and reporting of a channel state, wherein the configuration information includes at least two from among a first value (L) indicating the number of beams to be reported via a precoding matrix indicator (PMI), a second value (PCSI-RS) indicating the number of ports of a channel state information reference signal (CSI-RS), and a third value (LCSI-RS) indicating the number of beam ports to be used from among the number of ports of the CSI-RS; receiving, from the base station, one or more CSI-RSs that are transmitted via one or more beamformed ports; generating the PMI, on the basis of the result of measuring the received CSI-RSs, and the configuration information; and reporting, to the base station, CSI including the PMI.
