Patent ID: 8798653

Claim:
A system, comprising: a serving base station comprising a co-channel interference avoidance medium access controller (CIA MAC), the CIA MAC comprising transmission randomization capability; a feedback link between the serving base station and a subscriber station, wherein an interference report is received by the serving base station on the feedback link when an interference-to-carrier ratio exceeds a predetermined threshold; and an interference reporting link between the serving base station and a second base station, the serving base station and the second base station further comprising physical layer optimization, wherein the base stations determine power allocation and rate parameters for a link between the base station and the subscriber station and the serving base station sends the interference report over the interference link to the second base station; wherein transmissions to the subscriber station are randomized based on a channel threshold for the subscriber station, and the power allocation is calculated in the CIA MAC of the serving base station, wherein the power allocation calculation is given by: if P m < P _ 1 - F ⁡ ( H _ ( i , j ) k * ) , P ( i , j ) k * ⁡ ( h ) = P m ⁢ ⁢ for ⁢ ⁢ h ≥ H _ ( i , j ) k * , otherwise, P ( i , j ) k * ⁡ ( h ) = { P m υ * < R ′ ⁡ ( hP m n o ⁢ W ) ⁢ h n o ⁢ W 0 υ * ≥ R ′ ⁡ ( hP m n o ⁢ W ) ⁢ h n o ⁢ W R ′ - 1 ⁡ ( υ * ⁢ n o ⁢ W h ) ⁢ n o ⁢ W h otherwise , where h≧ H * (i,j) k • R′ −1 ( ) is an inverse function of R′( ), and υ*≧0 is uniquely given by ∫ H _ ( i , j ) k ∞ ⁢ P ( i , j ) k * ⁡ ( h ) ⁢ f ⁡ ( h ) ⁢ ⅆ h = P _ .
