Claim:
A transmitted power control method of carrying out transmitted power control in accordance with a transmitted power control signal, the transmitted power control method being applied to a first device that carries out communication with a wireless link in a wireless communication system of a CDMA system, the transmitted power control signal indicating increase or decrease of transmitted power received from a second device of a communication companion, the transmitted power control method comprising: a data acquiring step that the first device acquires data for every wireless link or every path, the data indicating communication quality of a signal from the second device; and a comparing step that the first device compares a difference in communication quality indicated by the data acquired from the two wireless links or two paths with a reference value for determining whether to carry out transmitted power control based on the transmitted power control signal or not, wherein, in the case where the difference is less than the reference value, the transmitted power control based on the transmitted power control signal received with the wireless link or path with which the data indicating lower communication quality have been acquired is not carried out with the first device.
