Abstract :
The Enhanced Uplink or High Speed Uplink Packet Access (HSUPA) is designed to enable Internet applications in the uplink in UMTS networks. Its specification includes several new features which on the one hand increases throughput and decreases delay for the users, and on the other hand enables a better resource utilization on the network side. In this work, we explain the most prominent new features of the Enhanced Uplink and investigate their impact on the system and end-to-end performance with a special focus on different scheduling strategies. For the numerical results, a full-featured packet-level simulator has been implemented which enables the evaluation of UMTS networks with Rel. 99 users and Enhanced Uplink users in parallel.
