ABSTRACT:
A slot of a low multiplicity is processed to narrow transmission timing intervals for already-connected users and thereby to make preparation for a new user, and a slot of a high multiplicity is processed to keep the maximum transmission timing intervals for the already-connected users so that the preparation for the new user is not performed. As a result, it is possible to provide the slot prepared for the new user while maximizing the transmission timing intervals. Further, the transmission timing intervals for the already-connected users are kept as large as possible during the traffic channel for preventing the deterioration of characteristics, and the shifting of the transmission timing is performed for the new user during the control channel so that the optimum transmission timing intervals can be achieved when the traffic channel is established. A DSP (14) executes the processing.
