TRANSMISSION POWER CONTROL UNIT AND TRANSMISSION POWER CONTROL METHOD

摘要

On the receiving side, a measured quality of received data and a target quality are compared and a target SIR is variably controlled. At the same time, the target SIR and a measured SIR are compared, transmission power control information (TPC information) made by based on the comparison results is transmitted to a transmitting side and transmission power is controlled on the transmitting side based on the transmission power control information. Furthermore, whether the transmission power has reached a limit is monitored on the receiving side, and when it reaches the limit, the target SIR is fixed at the latest value not to be revised. When the communication environment changes and transmission power can be controlled, variable control of the target SIR is restarted.
