    Abstract: Today, the main purpose of a scheduler for Long Term Evolution (LTE) is to provide the best system performance. However, it may decrease the system performance to have latency and starvation of lower priority connections in a resource allocation phase. There has been little research performed on LTE downlink scheduling and resource allocation. This paper proposes an efficient algorithm that includes scheduling strategies and resource allocation mechanisms, to avoid the latency or starvation of lower priority connections and to maintain system performance in downlinks of LTE. The algorithm discusses five levels of bandwidth request situations to assign priority and to allocate the bandwidth for each connection. Therefore, we design an LTE downlink scheduling scheme and a resource allocation strategy that not only aims to achieve the system’s highest performance but also avoids latency and starvation problems. As shown in the results of simulations, the proposed algorithm can provide proportional fairness and high system performance in downlinks of LTE systems.
