In a communication system where a terminal operates in clock synchronization with a global time used on a network, a period of time required for establishing clock synchronization when the terminal synchronizes a local time with a global time prior to receiving or transmitting a frame. In the communication system where the terminal operates in clock synchronization with the global time used on the network, a normal frame is utilized as a sub-startup frame (A_su) for global time reference in addition to a startup frame (A_st), to thereby reduce the period of time required for establishing clock synchronization. Also, the reference auxiliary startup frame is set as an event signal to adaptively control a period of time that is occupied by the transmission of the reference frame.
