Abstract
A power control method applied to a radio network controller (RNC), a node B and a user equipment is provided. The method include steps of: determining a target block error rate; identify an initial signal-to-interference ratio (SIR) from a history look-up table (LUT) according to the target block error rate; estimating a measured block error rate between the RNC and the node B via the RNC; adjusting the initial SIR with reference to the measured block error rate and the target block error rate to generate an updated SIR; and controlling a signal transmission power of the user equipment with reference to the updated SIR via the node B.
