In this paper, we assume that the successful operation of the primary user requires a minimum-rate to be guaranteed by its channel for a certain percentage of time, and obtain the interference-power constraint that is required to he fulfilled by the secondary user. We investigate the capacity gains offered by this spectrum-sharing approach when the input transmit power of the secondary user is limited. In particular, we assume that only partial channel information of the link between the secondary's transmitter and primary's receiver is available to the former, and derive lower bounds on the capacity of a Rayleigh flat-fading channel with different transmission techniques, namely, channel inversion and constant-power transmission.
