Abstract
Techniques for determining a move list identifying radios—of a shared access system including at least one time division duplexing system—are provided. The radios transmissions in spectrum shared with an incumbent receiver cease upon the incumbent receiver entering a protection region.

A method for determining a move list for a region of points, comprising:
- determining an initial sort list of an Mth point of the region;
- if there is more than one time division duplexing (TDD) radio of a TDD system in the initial sort list, then generating a modified sort list for the Mth point with respect to look angles about the Mth point including at least two TDD radios within the neighborhood;
- generating at least one of:
- look angle removal lists for each look angle about the Mth point based upon determining interference levels of radios in the modified sort list, or the initial sort list if there is no modified sort list, for the Mth point;
- and
- a point move list for the Mth point based upon a union of the look angle removal lists;
- and
- generating, from the look angle removal lists or the point move list, the move list identifying radios whose transmissions cease upon an incumbent receiver entering the region.
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 initial sort list of an Mth point of a region;
- if there is more than one time division duplexing (TDD) radio of a TDD system in the initial sort list, then generate a modified sort list for the Mth point with respect to look angles about the Mth point including at least two TDD radios within the neighborhood;
- generate at least one of:
- look angle removal lists for each look angle about the Mth point based upon determining interference levels of radios in the modified sort list, or the initial sort list if there is no modified sort list, for the Mth point;
- and
- a point move list for the Mth point based upon a union of the look angle removal lists;
- and
- generate, from the look angle removal lists or the point move list, a move list identifying radios whose transmissions cease upon an incumbent receiver entering the region.
A system, comprising:
- shared access system (SAS) controller circuitry;
- wherein the SAS controller circuitry is configured to:
- determine an initial sort list of an Mth point of a region;
- if there is more than one time division duplexing (TDD) radio of a TDD system in the initial sort list, then generate a modified sort list for the Mth point with respect to look angles about the Mth point including at least two TDD radios within the neighborhood;
- generate at least one of:
- look angle removal lists for each look angle about the Mth point based upon determining interference levels of radios in the modified sort list, or the initial sort list if there is no modified sort list, for the Mth point;
- and
- a point move list for the Mth point based upon a union of the look angle removal lists;
- and
- generate, from the look angle removal lists or the point move list, a move list identifying radios whose transmissions cease upon an incumbent receiver entering the region.
