Abstract: Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Power control techniques can consider the effectiveness of interference cancellation before making power control determinations. For example, where interference with a base station from an interfering wireless terminal is being canceled such that the effects of that interference are not adversely affecting operations of the base station, the offending terminal can be left unchanged, or its transmit power can be increased. On the other hand, where the interference cancellation operation is not able to cancel the effects of the interfering signal sufficiently, the operation can lower the uplink transmit power of the offending signal so as to not cause interference to the other base station.
