Abstract :
In this paper we consider the performance of a UTRA TDD system with various slot configurations. UTRA TDD supports flexible and dynamic channel allocations thus it can he configured to different service needs. Uplink and downlink transmissions have different characteristics and in this study we are concentrating on the requirements for symmetrical services in dedicated channels. Effect of number of beacon channels per radio frame and effect of different uplink and downlink partitioning to TDD system capacity are analyzed with dynamic system level simulator. Although this study is limited to circuit-switched data service these findings can be used as a starting point when building up mixed traffic scenarios with asymmetrical services.
