Abstract (en)
[origin: WO2016080742A1] The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A base station capable of communicating with a user equipment (UE) includes a transceiver configured to transmit downlink signals containing a first reference signal (RS) configuration on downlink channels and a first set of RSs according to the first RS configuration for the UE, and receive, from the UE, uplink signals containing a precoding matrix indicator (PMI) derived using the first set of RSs, and a controller configured to convert the PMI to one of predetermined precoding vectors.
