METHOD AND APPARATUS FOR REDUCING INTER-CELL INTERFERENCE IN RADIO COMMUNICATION SYSTEM

摘要

A method of a first cell for supporting a downlink channel demodulation at a user equipment. The method according to one embodiment includes transmitting, by the first cell to the user equipment, information on a Cell-specific Reference Signal (CRS) of a second cell including at least one CRS antenna port count information of the second cell or Multicast/Broadcast over Single Frequency Network (MBSFN) subframe configuration information of the second cell; and transmitting, by the first cell to the user equipment, a downlink signal on the downlink channel. The information on the CRS of the second cell is used by the user equipment to demodulate the downlink channel.
