ABSTRACT:
In transmission power control in a CDMA mobile communication system which controls the uplink transmission power of a mobile station so as to obtain a target SIR, and also controls the target SIR based on the quality of the transmission path, when one mobile station transmits and receives the same data simultaneously with a plurality of base stations, the quality of each transmission path is monitored. The data received over the transmission path with the best quality is selected, and for each transmission path the selectivity of data sent over the transmission path is calculated, the target SIR is updated based on the data quality after data selection, and for each transmission-path the target SIR after updating is multiplied by the selectivity for each transmission path to obtain the actual target SIR for the transmission path.
