摘要

仅给出摘要形式，如下。高速下行分组接入(HSDPA)目前正在3GPP中进行R5和R6的标准化。HSDPA提供超过10mbit /s的峰值数据速率，与R99相比，显著提高了UMTS的分组业务频谱效率。HSDPA规范草案包括以下先进概念:自适应调制和编码方案(高达64 QAM);快速SAW混合ARQ;快速分组调度;潜在的，还有快速小区选择和MIMO信道概念。

High speed downlink packet access (HSDPA)-the path towards 3.5G

Summary form only given, as follows. High speed downlink packet access (HSDPA) is currently being standardized in 3GPP for R5 and R6. HSDPA offers peak data rates exceeding 10 Mbit/s and significantly enhances the spectral efficiency of UMTS for packet services compared to R99. The draft HSDPA specifications includes advanced concepts of: adaptive modulation and coding schemes (up to 64 QAM); fast SAW hybrid ARQ; fast packet scheduling; potentially, also, fast cell selection and MIMO channel concepts.
