METHODS AND APPARATUS FOR INTER-CELL INTERFERENCE COORDINATION

摘要

Systems and techniques for reducing or eliminating interference in licensed frequency bands. A device, such as a UE, upon recognizing that it is experiencing interference, transmits an inquiry using an unlicensed frequency band, such as a television white space (TVWS) band. A device that are potential sources of interference responds by transmitting a feedback signal providing information that can be used to identify it as an interferer. The device experiencing interference performs analysis to identify interferers, or simply transmits the feedback information to its base station. The base station, upon identification of one or more interferers, uses unlicensed frequencies, such as TVWS bands, to communicate with neighboring base stations to request reduction or elimination of interference. Neighboring base stations respond by taking actions that may include scheduling management or transmit power reduction to reduce interference by their served devices.
