NETWORK COORDINATION FOR IMPROVED INTERFERENCE CANCELLATION
First Claim
1. A method of wireless communication, comprising:
- determining that a victim user equipment (UE) is experiencing interference from a neighbor base station;
determining an ability of the victim user equipment to perform interference cancellation;
coordinating with a serving base station to adjust a level of interference experienced by the victim user equipment,wherein when the victim user equipment is capable of interference cancellation, the coordinating with the serving base station comprises at least one of;
adjusting the level of interference experienced by the victim user equipment and selecting a known transmission format, andwherein when the victim user equipment is not capable of interference cancellation, the coordinating with the serving base station comprises coordinating to decrease interference to the victim user equipment.

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.
