Simultaneous outage performance in a spectrum-sharing fading environment

We consider two different users sharing the same spectrum resource, interfering with each other, under outage performance requirements for both the users. We derive a practical condition to enable the spectrum-sharing under simultaneous outage performance. Furthermore, when the condition is fulfille...

Description
Summary:We consider two different users sharing the same spectrum resource, interfering with each other, under outage performance requirements for both the users. We derive a practical condition to enable the spectrum-sharing under simultaneous outage performance. Furthermore, when the condition is fulfilled, we provide equations to define the two-dimensional region of allocated powers (P 1 , P 2 ), for the two users, where a given simultaneous outage performance is achievable. Numerical examples are given to illustrate our results. The framework presented in this paper covers more general settings and the results can be used to build power scheduling and sharing rules for licensed or unlicensed bands.
