ADAPTIVE SEMI-STATIC INTERFERENCE AVOIDANCE IN CELLULAR NETWORKS

摘要

Techniques for the reuse of airlink resources in a cellular network are disclosed. A base station controller may gather information about load levels at adjacent sectors of the cellular network. The base station controller may generate and distribute a reuse reference to base stations serving mobile devices in the adjacent sectors. Alternatively, the base station controller may provide the load level information to base stations serving the adjacent sectors and the base stations may determine a sector reuse pattern. The reuse reference or reuse pattern may be adapted to sector load conditions and may designate any combination of carriers, time slots, and power levels for data transmission in a sector. The base stations may schedule data transmission to mobile devices in their respective sectors according to the reuse reference or reuse pattern. The base stations may modify their resource usage in response to changes in sector load.
