Patent ID: 8295153

Claim:
A method, comprising: providing at a first node a spectrum emission mask that comprises indications of both desirable emissions and undesirable emissions over a plurality of radio resource allocation units; using the spectrum emission mask for estimating a signal to noise ratio in individual ones of radio resource allocation units at at least one second node; selecting an appropriate modulation-and-coding scheme per radio resource allocation unit; and scheduling transmissions on the radio resource allocation units using the selected modulation-and-coding schemes; the method further comprising, receiving a beacon transmission from a second node, the beacon transmission indicating a receiver sensitivity of the second node, estimating a path loss to the second node that transmitted the beacon in accordance with knowledge of a transmission power with which the beacon was transmitted, and further comprising the first node taking into account at least its own distortion characteristics, the estimated path loss and the estimated signal to noise ratio, allocating transmit signal energy such that a sum of the desirable emissions and the undesirable emissions is less than limits imposed by the spectrum emission mask.
