Abstract: Among the numerous scheduling algorithm of resource allocation,few studies of scheduling strategies are focused on the distinction of multi-service’s QoS requirements．This paper proposed a new downlink scheduling algorithm to satisfy the Quality of Service (QoS) needs of multi-users’ real-time services and non real-times services in the Long Term Evolution (LTE),．From a cross-layer perspective,the algorithm introduced a weight factor on the basis of EXP algorithm．Simulation results show that the proposed algorithm reduces the users data drop rate and improves the system throughput considerably,while ensures the users’ fairness.
