Abstract
Dynamic resource allocation in 3GPP Long Term Evolution (LTE) for satisfying Quality-of-Service (QoS) requirement as well as improving the system throughput has gained significant attentions. In this paper, we proposed a buffer-aware adaptive resource allocation scheme for LTE downlink transmission to improve the overall system throughput while providing statistic QoS guarantee and keep certain fairness among users. Specifically, each users’ queue priority in the base station is ranked according to its remaining life time or its queue overflow probability which is estimated by applying large deviation principle. Based on the queue priorities, we dynamically allocate the Resource Blocks (RBs) for avoiding buffer overflow and guaranteeing the statistic QoS. The simulation results demonstrate that the proposed algorithm improves the system throughput and fairness while considerably reduces the average bit loss rate.
