We propose and study a generalized selection multiuser scheduling (GSMuS) scheme which ranks a total of L users awaiting transmission by their signal-to-noise-ratios (SNRs) and selects the Nc number of users with the largest SNRs for channel access. We analyze the error and outage probabilities, the individual- and sum-rates of the proposed GSMuS scheme taking into account the effects of adaptive modulation, statistical power allocation with minimum rate constraint, and generalized fading channels. Numerical results show that as the average SNR increases, assigning more than one users for simultaneous transmission (for a fixed total transmission power) will significantly improve the sum rate. The GSMuS scheme brings about a substantial scheduling gain with respect to conventional systems without SNR ranking.
