Abstract

In this paper, a resource scheduling algorithm for Long Term Evolution (LTE) downlink is proposed. It provides Quality of Service (QoS) guarantee to Guaranteed Bit Rate (GBR) services and also suit to the Non Guaranteed Bit Rate (Non-GBR). Different services possess different QoS needs in LTE system, based on this, 3GPP divide them into several types. In view of the division, we set priorities for different kinds of services to guarantee the transportation of GBR services which have high QoS needs. At the same time, we take the Media Access Control (MAC) layer logical channel priority into account, and consider users’ channel quality to acquire a higher cell throughput. Simulation results show that our scheme can improve the QoS of emergency services obviously at the cost of a certain amount of the non-real times’.
