Abstract:
1. A method for scheduling, at a mobile station (MS), data transmission and reception of neighbor base stations (BSs) adjacent to the MS in a wireless communication system, the method comprising: receiving a random number or a random sign through a specific downlink channel in a first time interval from each of the neighbor BSs; determining a BS, among the neighbor BSs, which is allowed to transmit and receive data in a second time interval, based on a priority of the random number or the random sign, a number of MSs within a cell served by each of the neighbor BSs and a number of time intervals used for data transmission and reception by each of the neighbor BSs prior to the second time interval; and transmitting a signal indicating that data transmission and reception in the second time interval are not possible, to at least one neighbor BS excluding the determined BS, wherein the determining comprises determining a BS which transmits a smallest value calculated by a following equation A as the BS which is to transmit and receive data in the second time interval, by comparing the random number or the random sign transmitted by the neighbor BSs: where RNi is the random number or the random sign transmitted by each of the neighbor BSs, Ni is the number of MSs within a cell served by each of the neighbor BSs, Mi is the number of time intervals used for data transmission and reception by each of the neighbor BSs prior to the second time interval.
