Abstract

In this paper we study the performance of a recently proposed scheduling technique, known as selective multiuser diversity scheme, when the users in the system have unequal average signal-to-noise ratios (SNRs). Numerical examples confirm that selective multiuser diversity reduces dramatically the feedback load but maintains a good portion of multiuser diversity gain.
