CPC Code(s): H04W72/542
Abstract: a master device repeats transmitting a channel map when determining that sharing of the channel map is succeeded since a reception confirmation signal from the slave device cannot be received normally although the master device transmits the channel map to the slave device. even though the numerical number of channel map transmissions reaches the first predetermined number of times, when determining that the channel map has never been shared even once, the master device disconnects communication connection with the slave device at a predetermined timing.
