摘要： Apparatus and methods of performing interference mitigation in a communication network. The interference mitigation can include a controller sending a message to a first access point instructing the first access point to measure at least one signal transmitted by a first wireless terminal communicating a signal having known characteristics; the controller receiving from the first access point signal measurement information; and the controller communicating at least some of the signal measurement information received from the first access point to a second access point.

摘要： Methods, devices and computer program products facilitate self-configuration and self-optimization of radio networks. An internal topology discovery is performed to assess characteristics of a plurality of access points within an internal network. An external cell discovery can also be performed to identify one or more access points operating within an external network. Based on the assessments obtained through the internal and/or external topology discovery processes, operational parameters are assigned to each access point within the internal network. Such operational parameters can include a transmit power associated with each radio node.

摘要： 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.
