Abstract
The invention provides channel allocation method which achieves a high frequency utilization efficiency while suppressing the average transmission power by transmission power control. Selection priority degrees and initial minimum transmission power control amounts are set for all radio channels allocated to the system. The initial minimum transmission power control amounts are set such that the radio channel having higher selection priority degree has higher or at least equal initial minimum transmission power control amount than the lower selection priority radio channel. Upon channel allocation, a radio channel is selected in accordance with the selection priority degree, by the way that calculating the transmission power control amount of the radio channel (S505 to S507), comparing the transmission power control amount with the initial minimum transmission power control amount (S508), and when the transmission power control amount is equal to or higher than the initial minimum transmission power control amount, then use of the radio channel is permitted.
