Abstract
A transmission power control method and an apparatus, which includes a base station and a mobile stations, can lower a transmission power of a counterpart station and assure a communication quality, such as a desired bit error ratio, block error ratio, and so forth. A control reference value is set for generation of a control instruction controlling the transmission power of the counterpart station in a closed loop, when error correction coding and interleaving are used together. The transmission power control method includes steps of receiving a signal transmitted from a communication counterpart station, measuring a reception quality value of each received time slot, control instruction determining step of periodically determining a control instruction depending upon the reception quality values of the plurality of slots and transmitting the control instruction to the counterpart station, whereby the control instruction is used for transmission power control of the counterpart station.
