Abstract:
A method and an apparatus for transmitting and receiving channel state information in a multi-antenna wireless communication system are disclosed. Specifically, a method for reporting channel state information (CSI), by a User Equipment (UE), in a multi-antenna wireless communication system, the method comprising receiving, from a base station, configuration information for single CSI reporting in which a non-precoded CSI-RS based CSI reporting and a beamformed CSI-RS based CSI reporting are combined, reporting a first Precoding Matrix Indicator (PMI) and/or a first Rank Indicator (RI) derived based on a non-precoded CSI-RS to the base station, and reporting a Channel Quality Indicator (CQI), a second PMI, and a second RI based on a beamformed CSI-RS to the base station, wherein a value of the first RI is determined as only a value belonging to a previously determined set.

Claim (Index 12):
The method of  claim 10 , wherein a precoding matrix for an antenna port, that is not mapped to the set of precoding matrixes in an antenna port array of the base station, is determined as one of precoding matrixes belonging to the set of precoding matrixes.
