摘要
针对HSDPA的目标,围绕HARQ技术进行研究,给出了N信道停等协议的性能分析及操作原理说明。结论是SAW ARQ操作机制简单、信令开销少。而且通过增加并行操作的子信道数,可以做到提高吞吐量,减少传输时延的作用,同时还能降低接收端对缓冲容量的要求。
The protocols of the limited times packet retransmission is presented. The analysis of the performance and the operation mechanism of the N-channel slop-and-wait prolocol is simple and the signaling payoff is small. With the increase of/he parallel channel quantity the system /hroughput.is improved, the transmission delay is decreased and the receiver buffer is reduced
