N2 - In this paper, we propose two new threshold based parallel multiuser scheduling schemes, namely (i) an on-off based scheduling (OOBS) scheme and (ii) a switched based scheduling (SBS) scheme. The objective is to reduce the complexity of implementation without a considerable performance loss in comparison with selection based scheduling. While the OOBS scheme schedules all the users with an SNR above a fixed pre-selected signal to noise ratio (SNR) threshold, the SBS scheme schedules only the K3 users with an acceptable SNR if there are enough acceptable users. Otherwise, the scheduler selects the best Ks users. We analyze statistical characteristics and performances of these proposed schemes. Numerical results show that the proposed schemes can offer some decrease in the average number of feedback load without an important degradation in average bit error rate and average spectral efficiency.
