Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. To this end, a base station using a large-scale antenna transmits, to a terminal, reference signal resource configuration information including multiple pieces of reference signal configuration information and reference signal port information, for transmission of a reference signal, and transmits the reference signal to the terminal using some or all of channel measurement resources indicated by the multiple pieces of reference signal configuration information and the reference signal port information included in the reference signal resource configuration information. In this case, the channel measurement resources may correspond to antenna ports, the number of which is indicated by a combination of the multiple pieces of reference signal configuration information and the reference signal port information.

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.
