Abstract :
This work analyzes the outage probability of fair physical layer schedulers that select a pair of orthogonal users for simultaneous transmission. These schemes rest on finite-rate channel state information compatible with 3GPP specifications and differ with respect to their usage of channel quality indicator in scheduling decisions. Closed-form approximations for the outage probability of these practical transmission schemes are derived. Important outage capacity gains are observed when these multiuser scheduling strategies are compared to the scheme that transmits sequentially to only one user at a time.
