Abstract: Provided are a method and apparatus for transmitting and receiving channel information in a wireless communication system. The method for transmitting and receiving channel information in a wireless communication system includes: receiving information about a channel information providing method from a base station; receiving, from the base station, a reference signal for measuring a channel status between the base station and the terminal; determining channel information for a plurality of services, based on the information about the channel information providing method and the reference signal; and transmitting, to the base station, the channel information for the plurality of services.

Abstract: Disclosed are feedback and transmission devices and methods in full-dimension multi-antenna systems using two-dimensional (2D) planar array antennas, wherein a UE estimates channel states each corresponding to a respective one of multiple domain channels by a reference signal received from a base station, and obtains precoding matrix indicators (PMIs) each corresponding to a respective one of the multiple domain channels and rank indicators (RIs) each corresponding to a respective one of the multiple domain channels based on the estimated channel states. The UE may determine a joint rank indicator (JRI) using the obtained PMIs and the RIs and transmit feedback information containing the determined JRI to the base station.
