In this paper, a multiservice transmission scheme 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. The proposed selection is based on buffer occupation, delay requirements and target bit rate, keeping power constraints. This power restriction depends on the estimated residual capacity and the contribution of this particular mobile user to the system load. Service multiplexing in upper layers (logical channels) sharing a common transmission rate (transport channel) has been evaluated by means of two different dequeueing strategies.
