Abstract

High speed downlink packet access (HSDPA) is a technology to extend the peak data rates and capacity of 3G mobile data transmission systems. It targets especially favorable radio channel environments with the possibility to use higher order modulation and higher code rates. Furthermore fast retransmissions and enhanced scheduling algorithms can be used to boost data rates and to provide the required quality of service (QoS). A dynamic W-CDMA system level simulator has been extended to enable the simulation of packet switched services with special focus on HSDPA. The complete simulation system contains traffic sources that create sequences of packets for each active user equipment (UE), models the protocol stack and provides the possibility to collect performance indicators, e.g. sector packet data throughput, page throughput, and packet delays, in different scenarios for offline analysis. The simulation tool will be described and some example results concerning packet data performance of HSDPA will be shown.

基于HSDPA的UMTS FDD网络性能分析模拟器

高速下行分组接入(HSDPA)是一种扩展3G移动数据传输系统峰值数据速率和容量的技术。它的目标是特别有利的无线电信道环境，可以使用更高阶的调制和更高的码率。此外，快速重传和增强的调度算法可用于提高数据速率并提供所需的服务质量(QoS)。扩展了动态W-CDMA系统级模拟器，使其能够模拟分组交换业务，并特别关注HSDPA。完整的仿真系统包含为每个活跃用户设备(UE)创建数据包序列的流量源，对协议栈进行建模，并提供收集性能指标的可能性，例如扇区数据包数据吞吐量，页面吞吐量和数据包延迟，在不同的场景下进行离线分析。本文将介绍该仿真工具，并给出有关HSDPA分组数据性能的一些示例结果。
