QoS tuning and resource sharing for UMTS WCDMA multiservice mobile

This paper studies the uplink of the universal mobile telecommunications system flexible physical layer. It recalls the semistatic approach of transport highlighting key parameters of its control and proposes an external analytic model of the mobile physical layer. This approach is adapted to radio resource management in a multiservice environment, accounting for the relationships between the link and the system levels. This paper clearly shows the impact of the rate matching mechanism on the transmission performances at link level for transport channels multiplexed in the uplink. It refines the power index notion useful at the system level as an indicator of resource consumption and transmission quality of the physical data and control channels. Integrating inter- and intramobile multiservice features with performance tables (considering environment influence, channel coding type, etc.) leads to a cost function of the transport format combinations; a valuable tool for the evaluation of the uplink multiservice cellular capacity. Several multiplexing cases are then studied under the joint aspects of quality tuning and resource consumption. © 2002 IEEE.
