APPARATUS FOR TRANSMITTING AND RECEIVING SIGNAL IN DISTRIBUTED ANTENNA SYSTEM
Abstract:
A method of receiving a reference signal by a user equipment. A first channel state information-reference signal (CSI-RS) configuration related to a discovery of a transmission point is received. A second CSI-RS configuration related to a CSI measurement is received. A CSI-RS according to the first CSI-RS configuration or the second CSI-RS configuration is received. Feedback information is transmitted to a base station. If the CSI-RS has been received according to the first CSI-RS configuration, the feedback information includes information on a CSI-RS received strength. If the CSI-RS has been received according to the second CSI-RS configuration, the feedback information includes a result of the CSI measurement.
