FEEDBACK METHOD IN COORDINATED MULTI-POINT COMMUNICATION SYSTEM AND APPARATUS THEREOF

摘要

The present invention relates to a wireless communication system, and more specifically to a method and an apparatus for feeding back the muting point information in a coordinated multi-point communication system. A method for enabling a terminal to transmit feedback information for the coordinated transmission in the wireless communication system according to one embodiment of the present invention comprises the steps: receiving reference signals for the feedback of the channel state information from a plurality of base stations capable of participating in the coordinated transmission; measuring each channel state value for the plurality of base stations based on the reference signals; and transmitting the muting point information to indicate the preferring base station participating in the coordinated transmission among the plurality of base stations.

1. A method for transmitting feedback information with respect to coordinated multi-point (CoMP) transmission in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving reference signals for feedback of channel state information (CSI) from a plurality of base stations capable of participating in CoMP transmission; measuring channel state values with respect to the plurality of base stations on the basis of the reference signals; and transmitting muting point information determined on the basis of the channel state values and indicating a preferred base station not-participating in CoMP transmission from among the plurality of base stations.
