RADIO COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To make information transmission efficient in a radio communication system in which a master station device 1 wirelessly transmits output target information to slave station devices 2 and 3.SOLUTION: A master station device generates and transmits a signal to which storage identification information is added and, if necessary, output timing designation information is added, the signal including output target information. Based on a received signal, if the storage identification information indicates immediate output, a slave station device outputs the output target information, or if the storage identification information indicates storing and the output timing designation information is not added, the slave station device stores the output target information and performs a predetermined display, or if the storage identification information indicates storing and the output timing designation information is added thereto, the slave station device stores the output target information and outputs the stored output target information at the designated output timing.
