Abstract:
1. A method for frame-based, on-demand (FB-OD) spectrum contention in a wireless cognitive radio communication system including a plurality of base stations, the method comprising: maintaining a schedule of assignments (SchAs) of frames, within a communication channel, to the base stations, wherein each frame is assigned in its entirety to at most one base station for exclusive use for communication services by the base station; communicating the SchAs between base stations; identifying a demand for additional shared spectrum resources within a cell of a first base station within the plurality of base stations; determining whether the demand is originating external to the cell of the first base station or whether the demand is originating internal to the cell of the first base station; determining whether the communication channel can be exclusively used by the first base station; and responsive to exclusive use of the communication channel being denied to the first base station, conducting a FB-OD spectrum contention between the first base station and at least one other of the plurality of base stations for exclusive use in its entirety of at least one of a plurality of data frames associated with the communication channel; and resolving the FB-OD spectrum contention on a frame-by-frame basis.
