Abstract: The present invention provides a method of power control for a plurality of secondary users (SUs), or unlicensed users, in a cognitive radio network having a plurality of primary users (PUs), or licensed users. The method comprises determining an optimal power level for each of the SUs such that a total throughput of all the SUs is maximized while satisfying an individual throughput requirement of each SU and an interference limit constraint of the PUs. In particular, a case having two SUs is considered.

Abstract translation: 本发明提供了一种在具有多个主用户（PU）或许可用户的认知无线电网络中的多个次要用户（SU）或非许可用户的功率控制的方法。 该方法包括确定每个SU的最佳功率电平，使得所有SU的总吞吐量最大化，同时满足每个SU的单个吞吐量要求和PU的干扰限制约束。 特别地，考虑具有两个SU的情况。
