Abstract :
A multiservice transmission scheme, which combines voice, video, interactive games and signalling, is evaluated for the dedicated channel of the Universal Mobile Telecommunications System. The transmission rate for each service is determined according to its QoS requirements by means of an adaptive transport format selection based on buffer occupation, delay requirements and target bit rate keeping power constraints. Video and games services are multiplexed in upper layers (logical channels) sharing a common transmission rate (transport channel). Two strategies to share this rate are evaluated. A system level simulator, implemented in C++, which includes propagation conditions, traffic and mobility models and results from a physical layer simulator, allows the performance of the proposed scheme to be evaluated.
