Abstract:
1. A transmission power control method that compares error rate of receive data and target error rate on a receiving side, controls target SIR by a result of the comparison, and causes a transmitting side to control transmission power in such a manner that measured SIR will agree with the target SIR for each slot that constitutes a frame of a dedicated physical channel, comprising the steps of: determining whether a slot is a slot in which data is being transmitted by a data channel; comparing the error rate of receive data after decoding and the target error rate of the data and controlling the target SIR by a result of the comparing in the slot in which data is being transmitted by the data channel; measuring the error rate of a demodulated receive pilot in a slot in which data is not being transmitted and a pilot is being transmitted by a control channel; and controlling the target SIR upon comparing the measured error rate of the pilot and target error rate of the pilot in the slot in which data is not being transmitted and a pilot is being transmitted by the control channel.
