  • emptying a resource element of the serving base station that corresponds to a signal transmitted from a neighbor base station to a mobile station, before the mobile station computes expected channel quality information of the signal transmitted from the neighbor base station to the mobile station;

    receiving, from the mobile station, channel quality information of a signal transmitted from the serving base station to the mobile station, and the expected channel quality information;

    comparing the channel quality information with the expected channel quality information; and

    determining whether the neighbor base station is eligible to perform the coordinated multipoint transmission with the serving base station based on a result of the comparing.
