摘要:
A method and apparatus for selecting and allocating antennas efficiently are provided. The method includes transmitting, to a User Equipment (UE), information indicating a configuration of a plurality of Channel Status Information Reference Signals (CSI-RSs) through UE specific signaling during an initial access attempt with the UE; receiving, from the UE, CSI-RS measurement results indicating configured CSI-RSs; transmitting CSI-RSs corresponding to a set of available distributed ports (D-ports) based on received signal strength information included in results of the CSI-RS measurement; and determining a CSI-RS of a selected D-port set for use in communications based on feedback information received from the UE.
