Method for transmitting and receiving channel state information in wireless communication system and device therefor

Abstract

Disclosed are a method for transmitting and receiving channel state information in a wireless communication system and a device therefor. Specifically, a method for transmitting channel state information (CSI) by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, setting information for a single CSI process including a first channel state information-reference signal (CSI-RS) configuration, which is associated with K CSI-RS resources of a beamformed CSI-RS type, K being greater than one, and a second CSI-RS configuration, which is associated with one CSI-RS resource of the beamformed CSI-RS type; reporting, to the base station, an indicator indicating a CSI-RS resource selected from among the K CSI-RS resources; and reporting, to the base station, a channel quality indicator (CQI)/precoding matrix indicator (PMI)/rank indicator (RI) derived on the basis of the one CSI-RS resource.

Dependencies are inferred from the claim text.
