Abstract
Communications by base stations in wireless communication networks may be coordinated in a manner to improve performance by mobile devices experiencing interference from non-serving base stations. In particular, base station communications may be coordinated to improve the performance of interference cancellation by mobile devices. If a user equipment (UE) experiencing interference is capable of interference cancellation, then the base stations may coordinate to increase interference to that user equipment so as to improve that UE's ability to perform interference cancellation. Base stations may also coordinate to reduce interference for a UE, regardless of the UE's ability to perform interference cancellation. Mobile device performance improvements may also be achieved by coordinating scheduling of resources by the non-serving base stations, by using communication formats compatible with interference cancellation, by spatial coordination.
