摘要
多速率方案考虑如何以灵活、有效的方式将不同速率和质量要求 (QoS)的业务进行复用 ,它是第三代移动通信系统的重要特征之一 .速率匹配算法是多速率方案的核心算法 .本文以 3GPP最新制订的WCDMA(FDD)多速率方案为基础 ,对上 /下行链路的速率匹配算法进行了详细的比较与分析 。
Multirate scheme in WCDMA (Wideband Code Division Multiple Access) deals with how to multiplex several services with different rates and Quality of Service (QoS) in a flexible and efficient way, and is a distinct characteristic in the 3G mobile communication systems. Rate Matching Algorithm is the key algorithm in Multirate scheme. According to the latest WCDMA (FDD) multirate scheme of 3GPP (3G partnership project), This paper presents detailed comparison and analysis of rate matching algorithm in the uplink/downlink, and carries out some preliminary discussion about its possible improvement.
