This paper describes the structure of a simulator developed for the ATDMA project for assessing the performance of an adaptive radio interface in a 3rd generation cellular system. Particular attention is given to the Resource Allocator (RA) module along with its interaction with other subsystems in the model. The function of the RA module is complicated by the fact that it is required to deal with requests from the many different techniques of the ATDMA system model, such as medium access, link adaptation, dynamic channel allocation and ARQ, as well as long term processes such as handover and admission control. The paper deals with the queuing and prioritising functions of the ATDMA model and the practical limitations which must be incorporated within the simulator for realistic assessment of system performance.
