Abstract
A technique for decreasing noise and interference in an uplink of a wireless communication system includes detecting, at a serving base station, noise and interference levels above a threshold. In response to the detecting, a noise and interference measurement frame is scheduled that includes respective allocated portions for respective active subscriber stations and respective unallocated portions that are adjacent to the respective allocated portions and are not allocated to one of the respective active subscriber stations. The respective allocated portions and the respective unallocated portions are configured in a selected pattern in the noise and interference measurement frame. The respective noise and interference levels are determined, at the serving base station, in the respective unallocated portions of the noise and interference measurement frame. One or more rogue subscriber stations, included in the respective active subscriber stations, are then identified based on the respective noise and interference levels associated with the respective active subscriber stations. When it is ambiguous as to whether a subscriber station is a rogue subscriber station, additional noise and interference measurement frames may be scheduled to resolve the ambiguity.
