Method and system for determining transmission power of radios of a time division duplexing system

A program product comprising a non-transitory processor-readable medium on which program instructions, configured to be executed by a programmable processor, are embodied, wherein the program instructions are operable to:

• determine an interference contribution in a frequency spectrum at a point, where the interference contribution is determined for each time division duplexing (TDD) radio, of a TDD system, in a neighborhood around the point;
• select a TDD radio, of the TDD system, in the neighborhood having a largest interference contribution at the point and in the frequency spectrum;
• determine a transmit power level for the selected TDD radio;
• using the determined transmit power level of the selected TDD radio, determine a second interference contribution, of the selected TDD radio, at the point and in the frequency spectrum;
• using the second interference contribution, determine a transmit power level for each of at least one TDD radio of the TDD system that is not the selected TDD radio;
• and
• send each determined transmit power level, for each of the at least one TDD radio, which is configured to transmit, in the frequency spectrum that is shared spectrum, at a corresponding transmit power level.

A system, comprising:

• shared access system (SAS) controller circuitry;
• wherein the SAS controller circuitry is configured to:
• determine an interference contribution in a frequency spectrum at a point, where the interference contribution is determined for each TDD radio, of a time division duplexing (TDD) system, in a neighborhood around the point;
• select a TDD radio, of the TDD system, in the neighborhood having a largest interference contribution at the point and in the frequency spectrum;
• determine a transmit power level for the selected TDD radio;
• using the determined transmit power level of the selected TDD radio, determine a second interference contribution, of the selected TDD radio, at the point and in the frequency spectrum;
• using the second interference contribution at the point from the selected TDD radio, determine a transmit power level for each of at least one TDD radio of the TDD system that is not the selected TDD radio;
• and
• send each determined transmit power level, for each of the at least one TDD radio, to a corresponding TDD radio which is configured to transmit, in the frequency spectrum that is shared spectrum, at a corresponding transmit power level.
