Abstract: A method, components and a system are provided for implementing power control for wireless communication transmissions that provides, inter alia, a remedy for the mismatch of initial transmission power for NRT data by estimating a bias error based and adjusting the transmission power by a compensation amount for an averaged bias error estimation over all data set transmissions, such as sequential Temp-DCH allocations in a UMTS system. An alternative approach for a UMTS system estimates the bias error at a RNC based on an averaged transmit code power measurement by a base station and applies a bias error compensation to the initial DL transmit power at the RNC.

Abstract: A method system and components for outer loop power control particularly useful for non-real time/real time data services uses data transmitted in many bursts of short duration, called Temp-DCH allocations. A target metric, preferably, target SIR, is adjusted with differing step up and step down levels to converge on a relatively low steady state level of step up and step down target metric adjustments. The initial target SIR and the transient step size for target SIR adjustment is determined in a dynamic way in the outer loop power control for each Temp-DCH allocation of non-real time data.
