Method and apparatus for spectrum allocation in wireless networks
First Claim
1. An apparatus configured for determining allocation of spectrum, the apparatus comprising:
- a processor and a memory communicatively connected to the processor, the processor configured to;
receive a representation of a conflict graph, wherein the representation of the conflict graph comprises a first vertex representing a first base station of a first wireless service provider anda second vertex representing a second base station of a second wireless service provider, wherein the representation of the conflict graph further comprises an edge between the first vertex and the second vertex,wherein the edge is configured to represent at least one spectrum allocation constraint, wherein the at least one spectrum allocation constraint comprises at least one cross-provider conflict constraint; and
determine, based on the representation of the conflict graph, a spectrum allocation for at least one of the first base station or the second base station.

Abstract
The invention includes a method and apparatus for dynamically allocating spectrum available within a region including a plurality of base stations. The method includes obtaining a plurality of spectrum demands associated with at least a portion of the base stations, each spectrum demand requesting a portion of the available spectrum, and determining a plurality of spectrum allocations satisfying at least a portion of the spectrum demands. The spectrum allocations are determined by processing the spectrum demands using network information such as base station information associated with the base stations and region information such as terrain information associated with the region. The region information may include signal propagation information.
