Communication channel allocating system for traveling object digital communication system

Abstract

Abstract PURPOSE:To simultaneously instruct a communication channel to plural moving stations and to instruct other control such as transmission output adjustment or the like to the moving station under communication by constituting and outgoing control channel to be transmitted from a base station of a time division channel slot. CONSTITUTION:An outgoing control channel 10 is divided into an announcement information area 7 and a communication channel allocation area 8 and further, the communication channel allocation area 8 is divided into plural slots. Then, the pair of the announcement information area 7 and the communication channel allocation area 8 is periodically repeatedly transmitted. On the other hand, the base station transmits the transmission order control by the communication channel slot corresponding to the distance from the moving station. Thus, the channel can simultaneoulsy be allocated to the plural moving stations, and while the moving station allocated the communication channel is under communication, the base station can announce the other control item to the moving station and can announce the transmission order control corresponding to the distance without prolonging guard time.
