WCDMA HSUPA技术中的Node B调度算法研究

Investigation of Node B scheduling algorithms in WCDMA HSUPA technique

HSUPA(High Speed Uplink Packet Access)是继HSDPA(High Speed Downlink Packet Access)后,WCDMA(Wideband Code Division Multiple Access)标准的又一次重要演进。阐述了HSUPA采用的三种主要技术之一的基于Node B(基站)的快速调度,讨论了HSUPA可以采用的几种分组调度算法,并对几种算法作了简要比较。

HSUPA（High Speed Uplink Packet Access）is another important evolution of WCDMA（Wideband Code Division Multiple Access）standard just following HSDPA （High Speed Downlink Packet Access）. This paper presents the Node B based fast scheduling which is one of the three important techniques in HSUPA, and discusses several packet scheduling algorithms which can be adopted in HSUPA. Finally, these scheduling algorithms are briefly compared.
