Abstract:
1. An apparatus for sharing frequencies in a worldwide interoperability for microwave access (WiMAX) wireless communication system, wherein the apparatus comprising: memory; and a processor communicatively coupled to the memory, wherein the processor is configured to perform a method comprising: detecting an interference signal in the radio frequency band; setting, based upon the interference signal, interference indication information in a modified forward control header (FCH) of a downlink frame to be sent to a 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 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.
