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.
