Abstract

Non-static transmission time interval (TTI) strategy is investigated in this paper, in order to improve the available potential performance of the enhanced uplink dedicated channel in universal telecommunication radio access low chip rate time division duplex system (UTRA LCR TDD). This strategy introduces a joint support of two kinds of TTI, 20ms and 5ms TTI. For 5ms TTI is competitive at end-to-end delays and buffering requirement, while 20ms TTI performs better in terms of mobile terminal power saving, cell coverage and overhead reduction. The simulation results show that with non-static TTI strategy, mobile power saving increases by 3.5% in PB3, 15.6% in VA30, and the uplink capacity increases by 10%.
