Abstract: Scheduler is part of MAC Layer that executes fair throughput. A good scheduler provides high Quality of Service (QoS) and work towards getting better throughput. There are varieties of Schedulers based on different factors such as fairness, maximum feedback, etc. Priority Scheduler is based on the need of the service to be catered. We have designed a priority based scheduler on the top of ZF-MUMIMO scheduler. The Proposed scheduler is two-level scheduler. We will study the performance of designed Priority scheduler for Binary Symmetric Channel and M-ary Channel Models, in this paper.
