Abstract

The Enhanced Uplink (EUL) is expected to provide higher capacity, increased data rates and smaller latency on the communication link from users towards the network. A key mechanism in the EUL traffic handling is the packet scheduler. In this paper we present a performance comparison of three distinct EUL scheduling schemes (one-by-one, partial parallel and full parallel) taking into account both the packet level characteristics and the flow level dynamics due to the random user behavior. For that purpose, we develop a hybrid analytical/simulation approach allowing for fast evaluation of performance measures such as mean file transfer time and fairness expressing how the performance depends on the user’s location.
