The increasing demand for cellular communications leads to the development of Long Term Evolution (LTE). LTE is the evolution for existing 3G mobile networks which offers higher capacity, efficient utilization of radio resources, lower latency. As a core functionality of LTE downlink radio resource management, packet scheduling algorithms plays a vital role. Maximum SNR (Max SNR), round robin, proportional fair are the conventional scheduling algorithms. The main contribution of max SNR is towards maximizing system throughput.
