摘要： A method is provided for uplink scheduling for a mobile station (MS) in a base station (BS) in a wireless mobile communication system in which the MS sends channel quality information to the BS. At least two logical regions are set to control transmission power of the MS and the number of sub-channels to be allocated to the MS according to an interference level at which a signal of the MS affects an adjacent cell/sector. The BS allocates the MS to a specific logical region while considering channel quality information of the MS. When the specific logical region is mapped to a set of MSs whose interference to the adjacent cell/sector is large, the BS limits the transmission power of the MS and the number of sub-channels to be allocated to the MS to predefined reference values or less.
