Abstract

The OTA performance of Frequency Selective Scheduling (WiMAX Band AMC mode) is compared with that of Frequency Diverse Scheduling (WiMAX PUSC mode) as MS velocity is increased for Mobile WiMAX 802.16e. Frequency Selective Scheduling is shown to outperform Frequency Diverse Scheduling for velocities less than 15km/h and demonstrates upto 50% gain in throughput over the latter. The practical implications of this margin are: that pedestrian MSs in urban deployments may leverage the benefits of fast fading for performance gains without risk. And scheduler implementations can benefit from opportunistic switching between the two schemes given appropriate differentiating inputs.
