<P>PROBLEM TO BE SOLVED: To provide various techniques useful for time division multiplexing of a communication method. <P>SOLUTION: A communication device includes a transmission/reception unit and a communication processing unit. The transmission/reception unit is configured in accordance with a plurality of communication methods. The communication processing unit selects one communication method per time slot based on the device time from the plurality of communication methods in accordance with prescribed selection rules, and performs communication via the transmission/reception unit by the selected communication method. A first communication device, in time synchronization master processing 101, puts the device time Tdev of its own device as a time stamp 128 in a time synchronization request signal 120, and transmits the time synchronization request signal 120. A second communication device, in time synchronization slave processing 102, receives the time synchronization request signal 120, and calibrates the device time Tdev of its own device on the basis of the time stamp 128 in the time synchronization request signal 120. <P>COPYRIGHT: (C)2013,JPO&INPIT |
