Patent ID: 7486646

Claim:
A radio base station system for allowing path division multiple connection of a plurality of mobile terminal devices, and operating to transmit and receive signals to and from said plurality of mobile terminal devices on a basis of a plurality of slots, comprising: a measuring portion for measuring the number of the mobile terminal devices connected in each of said plurality of slots; and a transmission timing control portion for operating, for the slot used for the path division multiple connection of a predetermined number or more of the mobile terminal devices, to control transmission timings for the mobile terminal devices connecting in the path division multiple manner within a section allowing the transmission timing setting in the slot to maximize transmission timing intervals for the mobile terminal devices connecting in the path division multiple manner in the slot, and operating, for the slot used for the path division multiple connection of the mobile terminal devices fewer than said predetermined number, to control the transmission timing for the mobile terminal devices connecting in the path division multiple manner in the slot to ensure a section for assigning the transmission timing for a new mobile terminal device within the section allowing the transmission timing setting in the slot, and to assign the transmission timing for the new mobile terminal device requesting the connection to said ensured section.
