RADIO COMMUNICATIONS SYSTEM, AND MOBILE COMMUNICATION DEVICE AND TRANSMISSION CONTROL METHOD USED IN THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent indirect interference via radio transmission by a mobile communication device.

SOLUTION: A radio communications system allows a mobile communication device 3Y to perform radio transmission only during a time zone other than a time slot T1 which is allocated in a time division manner and dedicated to radio transmission from the mobile communication device 3Y. The mobile communication device 3Y receives multiple pieces of slot information SLx-SLz about a time slot T1 of a plurality of roadside communication devices 2X-2Z whose transmission timing is overlapped,and based on the received multiple pieces of slot information SLx-SLz, sets as its allowed transmission time a time zone allowed by all of the plurality of roadside communication devices 2X and 2Y whose transmission timing is overlapped.
