This paper discusses downlink power control of dedicated channels in UTRA TDD. The current UTRA TDD downlink power control is similar to the one in UTRA FDD mode, that comprises of closed inner loop and quality based outer loop. However, due to the time division feature and associated flexibility with asymmetry of TDD, the inner loop can not operate as fast as in FDD and it is affected by rapid changes in environment. Therefore, the effect of downlink power control of dedicated channel inner loop algorithm to the performance of UTRA TDD network is studied in this paper. A dynamic system level simulator is used for this purpose.
