PURPOSE:To increase the capacity of a system by grouping up-links from each mobile terminal equipments with closer call level to each other and allocating each group to each time slot so as to suppress a width of a control variable of a transmission power at each mobile terminal equipment to be a small value easily realized. CONSTITUTION:In the mobile communications system of the direct spread spectrum CDMA system, when a base station 1 receives a transmission radio wave from mobile terminal equipments 2-1-2-n, a time division multiplex control section 3 measures an incoming call level for each mobile terminal equipment to reference a slot management table 4 and allocates a time slot having a reference level with least difference from the incoming level of a mobile terminal equipment and registered in a slot management table 4. Then the number of the allocated time slot and the control variable of transmission power requiring adjustment are obtained and noticed to the mobile terminal equipments 2-1-2-n. In this case, number of up-links allocated to one time slot is not constant but changed dynamically. |
