Title: WIRELESS COMMUNICATION SYSTEMS WITH FEMTO CELLS
Abstract:
Systems and methods for avoiding interference signals sent by a femto node in a wireless communication system are described herein. In one embodiment, the method comprises establishing a communication link between a first transceiver and a base station. The base station is configured to provide wireless communication coverage within a first area. The method further comprises detecting by the first transceiver a femto signal generated by the femto node. The femto node is configured to provide wireless communication coverage within a second area to at least a second transceiver. The second transceiver is different from the first transceiver. The second area is smaller than the first area. The method further comprises identifying information indicative of a signal strength of the femto signal. The method further comprises transmitting a first message in response to detecting the femto signal, the first message comprising information identifying the femto node and the information indicative of the signal strength of the femto signal to the base station over a first frequency carrier. The method further comprises receiving a second message from the base station. The second message comprises information indicative of an instruction to communicate over a second carrier frequency. The method further comprises communicating with the base station over a second frequency carrier in response to the second message.
