一种LTE中MBMS系统的自适应调度算法
An Adaptive Scheduling Algorithm of MBMS in LTE System
摘要
Abstract
Multimedia broadcast/multicast service (MBMS) provides an effective solution for multimedia broadcast service.However,due to those users which under the worst channel condition,the performance of multicast system is strictly limited.To solve this problem,an adaptive scheduling algorithm for MBMS system in PtM mode is proposed.It adjusts the transmission rate according to average packet loss rate and provides better balance between multicast gain and multiuser diversity.The simulation results show that the proposed algorithm can effectively improve the system throughput without sacrificing user's satisfaction.关键词
