Abstract
The UMTS terrestrial radio access (UTRA), based on a wideband DS-CDMA techn ique, fully supports the UMTS requirements and has flexible support for rea l-time, variable-bit-rate services, as well as an efficient packet mode. Th is paper presents a description and a performance evaluation of a medium ac cess protocol which may be used in the UTRA system to provide constant-bit- rate (voice), variable bit-rate (video), and low priority data services. Th e performance evaluation of voice and data services has been carried out by a suitable analytical approach. Simulation results are also shown in order to validate analytical predictions.
