Abstract

The conditions for scheduling multiple users on a shared wireless channel strongly differ from those in wireline systems. The time-variant nature of the radio link in combination with adaptive modulation and coding schemes used in modern wireless systems gives way to a variety of resource assignment strategies. In particular, channel-aware scheduling algorithms increase the system performance by serving users when it is most favorable with respect to their present channel quality. In this paper, we compare several different channel-aware schedulers with a set of basic channel-independent reference algorithms at the example of a state-of-the-art HSDPA system. We discuss their characteristics and evaluate their performance in a single-service and a multi-service scenario.
