Abstract:
1. A method of reducing an inter-cell interference, which is reduced by a terminal in a multi-cell system, the method comprising: receiving information on at least one adjacent base station from a serving base station; receiving a reference signal from the at least one adjacent base station based on the information on the at least one adjacent base station; measuring an interference for each of transmitting antennas of the at least one adjacent base station using the reference signal; and transmitting interference information for each of the transmitting antennas to the serving base station, wherein the adjacent base station stops transmitting on at least one transmitting antenna on a specific radio resource based on the interference information for each of the transmitting antennas, and wherein the adjacent base station assigns a transmit power, reserved for the antenna not transmitting, to an antenna that is transmitting.
