The High Speed Downlink Packet Access (HSDPA)
is one of the newest extensions to the Universal Mobile Telecommunications
System (UMTS). HSDPA allows for higher data rates
due to new Adaptive Modulation and Coding (AMC) techniques,
a Hybrid Automatic Repeat Request (H-ARQ) protocol and a fast
scheduling algorithm. The fast scheduling, taking into account the
current channel conditions of each user, contributes significantly
to the performance of HSDPA by the so called multiuser diversity
gain.
Within the scope of this paper several scheduling algorithms
are introduced and are analyzed with respect to both, the
overall system performance and the individual user Quality of
Service (QoS) constraints. Results illustrate the trade-off between
the conflicting targets of high cell throughput and the delay
requirements for real-time services.
