Abstract:
A method and an apparatus for transmitting/receiving channel state information for use in multi-antenna system are provided. A signal communication method of a base station having a plurality of antennas in a wireless communication system includes determining antenna ports of first and second directions based on directions of the plurality of antennas, allocating channel measurement resources for the respective antenna ports to a terminal, transmitting a feedback configuration to the terminal according to the channel measurement resources, and receiving feedback information from the terminal based on the channel measurement resource and the feedback configuration. The signal transmission/reception method and apparatus are advantageous in transmitting/receiving channel state information efficiently in the system using a plurality of antennas.

Claim (Index 1):
A method by a base station in a wireless communication system, the method comprising:\n transmitting, to a terminal, at least one reference signal; and receiving, from the terminal, feedback information including a first precoding matrix indicator and channel quality information, wherein the first precoding matrix indicator is determined based on the at least one reference signal, and wherein the channel quality information is determined based on the first precoding matrix indicator and a second precoding matrix indicator selected by the terminal from a set corresponding to a plurality of precoding matrices, wherein the second precoding matrix indicator is not received from the terminal.
