碩士 === 國立臺灣師範大學 === 應用電子科技學系 === 101 === In this paper, a low computational complexity and effective way to improve the downlink resource allocation algorithm is presented, which involves the users of mix traffics over LTE-A (Long-Term Evolution Advanced) wireless networks. Our research objective is to guarantee the QoS (Quality of Service) requests from real time (RT) services and the proportional fairness (PF) of resource allocation from non-real time (NRT) services. The downlink resource allocation algorithm we proposed is able to schedule real time (RT) and non-real time (NRT) services according to each priority factor defined by us, and allocate resources through evaluating different priority factors. From the simulation results, it is shown that the performance of proposed algorithm not only guarantee the QoS for the RT services also helps improve the NRT services’ usage, so as to enhance the downlink transmission efficiency over LTE-A wireless networks.
