Abstract:
Provided are a method and apparatus for a UE (user equipment) to provide reference signal feedback in a wireless communication system. The method includes: receiving, from a base station, CSI-RS configuration information for configuring CSI-RS (channel state information reference signal) patterns, the CSI-RS configuration information containing usage information; performing a first measurement for radio resource management on all CSI-RS patterns configured based on the CSI-RS configuration information; and performing a second measurement only on CSI-RS patterns corresponding to the usage information, the second measurement being determined by the usage indicated by the usage information.
