An Improved Maximum C/I Scheduling Algorithm Combined with HARQ

导出

摘要 It is well known that traffic in downlink will be much greater than that in uplink in 3 G and that beyond. High Speed Downlink Packet Access( HSDPA ) is the solution to transmission for high speed downlink packet service in UMTS , of which Maximum C/I scheduling is one of the important algorithms related to performance enhancement. An improved scheme, Thorough Maximum C/I scheduling algorithm, is presented in this article, in which every transmitted frame has the maximum C/I . The simulation results show that the new Maximum C/I scheme outperforms the conventional scheme in throughput performance and delay performance, and that the FER decreases faster as the maximum number of the retransmission increases.
