WLC20-3: Channel Capacity and Fairness of SNR-Ranking-Based Parallel Multiuser Scheduling

We study the channel capacity and fairness performance of a generalized selection multiuser scheduling (GSMuS) scheme which ranks a total of L users awaiting transmission by their absolute or normalized signal-to-noise ratios (SNRs) and selects the Nc number of users for channel access. Compared to the selective multiuser scheduling (SMuS) scheme which chooses a single user with the largest SNR for channel access, the proposed GSMuS achieves both higher capacity and improved fairness.
