    摘要： Disclosed is a method for performing a soft handover in a Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiple Access (OFDMA) mobile communication system including a mobile station (MS), a serving base station (BS) and a plurality of neighbor BSs, each neighbor BS being different from the serving BS the serving BS providing a service to the MS. According to the method, the MS requests a soft handover to the serving BS when the serving BS detects that the MS must be handed over to one of the neighbor BSs, the serving BS notifies the neighbor BSs of the soft handover of the MS in response to the request for the soft handover, transmits signals to the MS using a predetermined coding scheme and a predetermined frequency region allocation scheme, and the neighbor BSs transmit signals to the MS using the predetermined coding scheme and the predetermined frequency region allocation scheme.
