摘要
HSUPA是TD-SCDMA的重要功能之一,由于目前所有关于HSUPA标准化的工作还集中在单载波上,考虑终端实现的复杂性,多载波HSUPA的标准还是一个空白。这里概述N频点HSUPA的关键技术,着重描述了引入N频点后对现有规范描述的HSUPA的影响。为了增强对上行分组业务的支持,考虑将混合自动重传(HARQ)、链路自适应编码(AMC)、基于NodeB的快速上行调度、功率分配及控制、速率控制等关键技术应用到上行,且在NodeB侧增加一个MAC-e实体,专门用来完成HSUPA的相关技术。在对TD-SCDMA系统采用N频点技术的基础上,结合HSUPA的关键技术,对当前TD-SCDMA系统协议中的HSUPA技术进行分析研究,得出多载波HSUPA技术方案对Iub接口的影响,及其关键技术的实现。
High Speed Uplink Packet Acess (HSUPA) technology is one of TD - SCDMA important functions, because present possesses about the HSUPA standardization work concentrates in the single carrier. Considering the complexity of realization, the multi -carrier HSUPA standard is still a blank. An overview of N frequency HSUPA, with emphasis on the key technologies and the introduction of N frequency on existing specifications described HSUPA impacts are provided,in order to enhance the uplink packet service support, taking into account the HARQ, AMC, fast based on NodeB, uplink scheduling and control, power distribution rate control key technologies such as applied to the uplink. And NodeB side: added a MAC -e entities is designed to complete the HSUPA of related technologies. The TD - SCDMA system N frequency technology on the basis of the key technology combined with HSUPA , the TD- SCDMA system protocol HSUPA technology is analysed,multi- carrier HSUPA technical solution for Iub interface,impact of the implementation of its key technologies are carried out.
