Abstract :
In this article convergence of UTRA TDD uplink dedicated physical channel (DPCH) power control is studied. Current uplink power control is based on several measurements, which involve both random and systematic errors. Outer loop power control is used to compensate the systematic error. Since the amount of systematic error is unknown in the beginning of a call and after each handover, the outer loop power control should adapt to the current conditions as fast as possible. In this paper the effect of the convergence speed of the outer loop power control to the UTRA TDD system performance is analyzed by the means of dynamic system level simulator
