Abstract
Techniques are provided for more efficiently determining frequency spectrum to allocate to General Authorized Access (GAA) citizens broadband radio service device(s) (CBSD(s)). Efficiency is enhanced by reducing a number of sets of frequency spectrum(s) by reducing a number of colors (assigned to nodes of connected set(s) of the network graph(s)) to which assignable frequency spectrum changes amongst the set(s).

A method for efficiently enhancing a function of an indicium of an aggregate of a product of bandwidth and maximum transmit power spectral density allocated to each of at least one general authorized access (GAA) radio, the method comprising:
- receiving co-existence data about at least the one GAA radio;
- identifying zero or more edges, wherein an edge is formed between two nodes, wherein an edge means that a criterion of interference at a GAA radio or a node consisting of at least one GAA radio exceeds an edge interference threshold level;
- generating at least one network graph, wherein a network graph means at least one connected set where there are no pairs of nodes that are connected with an edge and have a same color, and wherein a connected set means a unique set of at least two nodes where at least two of the at least two nodes have an edge, or a unique node with no edge to any other node, where each node of the at least two nodes having an edge are assigned different colors, and where a number of colors assigned to nodes of the connected set is a minimum number of colors which can be assigned to each node of the connected set;
- at a planned time, allocating a frequency spectrum and a maximum transmit power, in shared spectrum, to each of at least one GAA radio so that GAA radios, and each identified protection point, are free of interference from each of the at least one GAA radio, wherein free of interference and interference free mean a level of interference below a threshold level of interference, wherein the allocating the frequency spectrum and maximum transmit power comprises:
- identifying at least one protection point having an indicium of aggregate reduction of transmission power above a first indicium threshold level;
- for each identified protection point, determining at least one GAA radio having an indicium of a reduction of transmission power greater than a transmission power reduction threshold level, where each identified GAA radio comprises a node of a connected set;
- for at least one identified protection point, obtaining a diminished number of sets of at least one frequency spectrum for each connected set for the determined at least one GAA radio;
- for each obtained set of at least one frequency spectrum, determining an indicium of aggregate reduction of transmission power for GAA radios that are geographically located in a neighborhood of a corresponding identified protection point;
- and
- for at least one identified protection point, selecting an obtained set that has an enhanced function of an indicium of an aggregate of a product of bandwidth and maximum transmit power of each GAA radio authorized to transmit in the shared spectrum and geographically located in a neighborhood of a protection point;
- and
- sending the allocated frequency spectrum maximum transmit power to each authorized radio which is configured to have a transmit power, in the shared spectrum, not exceeding a corresponding determined maximum transmit power.
