Claim:
1. An uplink interference mitigation method performed by a base station (BS) in a communication system comprising: allocating, for a mobile station, a first set of frequency resource units related to a sector, wherein the first set of frequency resource units correspond to at least one bit position of a physical band bitmap; acquiring load information including load information of a neighboring sector, the load information being associated with interference occurring in uplink, wherein the load information associated with the interference is based on an interference level; determining whether the interference level is higher or lower than a threshold value; setting a second set of frequency resource units for the mobile station differently from the first set of frequency resource units if there is a third set of frequency resource units having the interference level higher than the threshold value; and performing uplink scheduling for the mobile station within the second set of frequency resource units, wherein the uplink scheduling includes allocating, for the mobile station, the second set of frequency resource units related to the sector with avoiding the third set of frequency resource units related to the neighboring sector based on the load information.
