Abstract:
1. A method of sharing frequencies in a worldwide interoperability for microwave access (WiMAX) wireless communication system, wherein the WiMAX communication system comprises a base station and a mobile device that work in a radio frequency band, the method comprising: detecting, by the base station, an interference signal in the radio frequency band; setting, by the base station, based upon the interference signal, interference indication information in a modified forward control header (FCH) of a downlink frame to be sent to the mobile device, the interference indication information indicating a frequency range that is occupied by the interference signal in the radio frequency band, wherein the modified FCH includes a downlink frame prefix in accordance with the WiMAX standard and a modified downlink frame prefix, wherein a portion of the downlink frame prefix that is in accordance with the WiMAX standard comprises a subset of the interference indication information, and where the modified downlink frame prefix comprises a remaining set of the interference indication information; and sending, by the base station, the downlink frame to the mobile device, such that the mobile device, based upon the interference indication information, avoids the frequency range where the interference signal is located.
