Abstract
Method, apparatus, and computer program product embodiments are disclosed for independent wireless resource sharing on a fair basis to enable selecting the most suitable coexistence between wireless networks. Example embodiments of the invention include a hierarchical resource request process that enables reallocation of radio resources in a coexistence band. When new resources are requested by a network, a search is made for free resources in the coexistence band. If this does not succeed, a check is made for any allocated but unused resources in the coexistence band that have been advertised by neighboring networks. If there are insufficient advertised resources, then the allocation of resources in neighboring networks is analyzed and compared with the requesting network's need for network resources. There are two graduated stages to the analysis. In an example light analysis stage, an analysis of the allocation of resources is limited to neighboring networks within the same network allocation group as the requesting network's. In a more extensive analysis stage, all of the neighboring networks are analyzed. In this manner, a more complete resource reallocation may be achieved.
