Apparatus and method for performing inter-cell interference coordination in a wireless communication system

摘要

An apparatus and method for controlling inter-cell interference is disclosed. The user equipment for controlling inter-cell interference in a wireless communication system includes an interference level measuring module configured to measure interference levels of neighboring cells using at least one of information about the number of antennas among antennas deployed in the neighboring cells, information about indexes of the effective antennas, and information about reference signal of the neighboring cells, an interference restriction request determination module configured to compare the interference levels of the neighboring cells with a predetermined threshold and to determine whether or not UE requests an interference restriction to the neighboring cells, and a transmitter configured to transmit information about one or more neighboring cells, to which the interference restriction request will be transmitted, to a serving base station.

1. A method for performing inter-cell interference coordination by a user equipment (UE) in a wireless communication system in which a plurality of antennas is deployed in each cell, the method comprising:
obtaining first information indicating a number of specific antennas from among a plurality of antennas of neighboring cells; obtaining second information about indexes of the specific antennas; obtaining third information about a reference signal of the neighboring cell; measuring interference levels of the neighboring cells using the first information, the second information, and the third information; comparing the interference levels of the neighboring cells with a predetermined threshold level and determining whether or not the UE requests an interference restriction to the neighboring cells; and transmitting information to a serving base station (BS) about one or more of the neighboring cells, to which the interference restriction request will be transmitted when the UE determines to request the interference restriction based on the compared interference levels, wherein the interference levels are transmitted to the neighboring cells by the serving BS.
