IEEE 802.22 networks consist of base stations and Consumer Premise Equipments (CPEs) where the base station in each cell opportunistically accesses and allocates (uplink and downlink) channels to all the CPEs in its cell. Information on white space (unused primary channels) availability is reported by the CPEs to the base stations. Thus, a base station's effectiveness to allocate channels are based on its ability to gauge the spectrum usage at various locations. In this paper, the authors propose a channel usage estimation framework where a base station uses the spectrum reports from other neighboring base stations to estimate the spectrum usage scenario at any arbitrary location within its cell.
