Abstract

Within the European RACE (Research in Advanced Communications for Europe) program several projects have contributed to the development and standardisation of third generation air interfaces. Therefore, several system concepts based on TDMA or CDMA have been developed. For both the selection procedures within the standardisation and a sound comparison of different systems, well defined scenarios and quality of service definitions are a prerequisite.

A major part of this paper concentrates on a description of the ATDMA (Advanced TDMA) system concept and on its evaluation. This project has designed an advanced TDMA radio access scheme for third generation systems. This system concept consists of various new techniques like packet access, novel handover schemes, and link control (a technique adapting the transmission chain to the propagation channel characteristics). Here, an investigation focusing on packet access including capacity issues is given.
