摘要

我们分析了3GPP提出的RLC (radio link control，无线电链路控制)的多拒绝(MR) ARQ的性能。mrarq的主要目的是通过减少应答次数来有效利用接收机的无线电资源。分析了无线衰落信道环境下MR ARQ和选择性重复ARQ的性能。数学分析和仿真结果表明，MR ARQ需要增大缓冲区的大小以在确认期间容纳数据包，并且在噪声较大的信道环境中MR ARQ需要增大缓冲区的大小。结果表明，随着确认周期的增加，为了达到饱和吞吐量，我们需要增加更多的缓冲区大小。为了有效地利用无线资源，需要增加缓冲区的大小，从而减少应答次数。此外，增加的延迟是另一个权衡。

Performance analysis of data transmission in W-CDMA system

We analyze the performance of multiple rejects (MR) ARQ for RLC (radio link control) proposed by 3GPP. The main purpose of MR ARQ is to get efficient use of radio resources at receiver by reducing number of acknowledgements. We analyze MR ARQ and compare its performance with selective repeat (SR) ARQ in the wireless fading channel environment. Based on mathematical analysis and simulation, it is shown that we need to increase the size of buffer for MR ARQ to hold data packets for the period of acknowledgement, and need to increase the size of buffer much more for MR ARQ in the noisier channel environment. It is shown that as the length of period for acknowledgement is increased, we need to increase the size of buffer much more for the saturated throughput. Increasing the size of buffer is needed for the efficient use of radio resources by reducing the number of acknowledgements. Also, the increased delay is another tradeoff.
