Patent ID: 8676125

Claim:
A wireless communication apparatus operable in a communication system, the wireless communication apparatus comprising: a receiver configured to measure at least one channel condition of at least one communication channel of a first communication node and determine spatial direction information of an interfering signal from the at least one channel condition; a first circuit configured to generate a request based on, at least in part, data indicative of the at least one channel condition and the spatial direction information, wherein the request informs a second communication node about a presence of interference from the interfering signal on the at least one communication channel caused by the second communication node, and wherein the request is configured to cause the second communication node to modify a physical characteristic of at least one transmitted wireless signal to reduce the interference by changing a geographical coverage area covered by the at least one transmitted wireless signal of the second communication node based on the spatial direction information of the interfering signal; and a transmitter configured to transmit the request to the second communication node.
