与HSDPA相似,HSUPA是上行链路方向针对分组业务的优化和演进。HSUPA改进了从移动终端到无线接入网络的上行链路传输。HSUPA的主要目标是:通过增强小区的吞吐量和高数据速率的覆盖范围,提高上行链路空中接口容量利用率和扩展数据业务的支持范围。
Similar to HSDPA, HSUPA is the optimization and evolution of the uplink for packet services. HSUPA improves the uplink transmission from the mobile terminal to the radio access network. The main goals of HSUPA are: • Increase uplink air interface capacity utilization and extend data service support by enhancing cell throughput and high data rate coverage.
