Abstract:
1. A method for supporting a handover in a broadband wireless access communication system that includes a Mobile Subscriber Station (MSS), a serving Base Station (BS) currently providing service to the MSS, and a plurality of neighbor BSs, in which each of the BSs includes cells using distinct subchannel bands, the method comprising the steps of: establishing a set of BSs that currently provide wireless channels for data transmission/reception to the MSS; classifying, by each BS, entire subchannels into a plurality of sets of subchannels; and allocating each of the plurality of sets of subchannels obtained by the classification to a Partial Usage of Subchannels (PUSC) subchannel area of each sector, said PUSC subchannel area being a location in a burst, wherein, every BS included in an active set selects an equal number of PUSC subchannels from among a PUSC subchannel area allocated to each of the BSs and allocates the selected PUSC subchannels to the MSS, wherein the MSS receives a downlink signal transmitted through each of the PUSC subchannel areas and performs a predetermined combining of all signals received from each of the BSs, and wherein, in the predetermined combining, all of the signals are individually compensated and then the predetermined combining is performed for the compensated signals by using channel state information as a predetermined weight.
