摘要
The High Speed Uplink Packet Access (HSUPA) technology for Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is used to improve the overall uplink performance: to increase the peak data rate and throughput and to reduce the transmission delay of uplink. The considered enhancements include Adaptive Modulation and Coding (AMC), Hybrid Automatic Repeat Request (HARQ), Node B fast scheduling and sharing of uplink channel resources between User Equipments (UE). New Media Access Control protocol entities (MAC-e and MAC-es) are adopted to enhance and optimize protocols. Simulation results of these technologies show that the system performance (including the peak rate, throughput, and delay) can be improved significantly.
