Method and system for frequency allocation in a shared access system

A non-transitory computer readable medium storing a program causing a computer to perform a method to allocate bandwidth to co-existence groups of a connected set in a spectrum access system (SAS), the method comprising:

• receiving data about co-existence groups in the connected set of the SAS, where such data includes a number of the co-existence groups, G, in the connected set, and a number of radios, ni, in each co-existence group;
• determining an allocated bandwidth for each of the G co-existence group by subtracting a splitting disincentive bandwidth for a co-existence group from a co-existence incentive bandwidth for the co-existence group;
• and
• sending the determined allocated bandwidths for the co-existence groups.

A spectrum access system (SAS), comprising:

• a processing system comprising processing circuitry coupled to memory circuitry;
• a communications system coupled to the processing system;
• radios coupled to the communications system;
• wherein the processing system is configured to allocate bandwidth to co-existence groups of a connected set in the SAS by:
• receiving data about co-existence groups in the connected set of the SAS, where such data includes a number of the co-existence groups, G, in the connected set, and a number of radios, ni, in each co-existence group;
• determining an allocated bandwidth for each of the G co-existence group by subtracting a splitting disincentive bandwidth for a co-existence group from a co-existence incentive bandwidth for the co-existence group;
• and
• sending the determined allocated bandwidths for the co-existence groups.
