Method and apparatus for dynamic spectrum sharing
First Claim
1. A method for dynamic spectrum sharing, comprising:
- identifying a plurality of radio nodes, for which plurality each radio node can measure a local signal value (local SV) of a protected transmission and for which plurality the radio nodes are within a uniform SV region of the protected transmission, wherein the local signal value is based on a signal power of the protected transmission at a radio node;
measuring the local SV at each radio node; and
determining a transmit decision for at least one of the plurality of radio nodes based on the local SV of each radio node in the plurality of radio nodes and at least one threshold value that is related to statistical characteristics of the protected transmission at an interference boundary of the protected transmission and a desired probability of non-interference with the protected transmission at the interference boundary, wherein the uniform SV region is a region within which a mean of the protected transmission power level over time at any two points within the region differs by no more than ±
6 db.

Abstract
A technique for dynamic spectrum sharing includes identifying (705) a plurality of radio nodes (115, 120), measuring (710) a local signal value (SV) at each radio node (110, 200), and determining (715) a transmit decision. Each radio node can measure a local signal value (SV) of a protected transmission and the radio nodes are within a uniform SV region of the protected transmission. The transmit decision is determined for at least one of the plurality of radio nodes based on the SV of each radio node in the plurality of radio nodes and at least one threshold value that is related to statistical characteristics of the protected transmission at an interference boundary (105) of the protected transmission and a desired probability of non-interference with the protected transmission at the interference boundary.
