Patent ID: 7072619

Claim:
A transmission-power control assisting apparatus, comprising: a transmission quality monitoring section for monitoring an trot, relative to a predetermined threshold, in transmission quality of any one of a plurality of radio channels which includes a specific radio channel, said plurality of radio channels to be set transmission powers en bloc as a value relative to a transmission power of the specific radio channel under transmission-power control; a period determining section for determining a predetermined period of time from either a point in time of an opportunity to append a radio channel other than said specific radio channel to said plurality of radio channels, or from a point in time when the radio channel is allowed to be appended; a desired-value setting section for varying a desired value for the transmission power of said specific radio channel by a predetermined value to suppress said error during a period other than said predetermined period of time and by a value larger than said predetermined value during said predetermined period of time; and a transmission-power update requesting section for transmitting at a predetermined frequency a control signal for the transmission-power control to a transmitting end which performs transmission via said plurality of radio channels, based on relation between the desired value set by said desired-value setting section and reception quality of said plurality of radio channels.
