Abstract: PURPOSE: A method and an apparatus for obtaining synchronization between nodes, and a method for organizing multiple physical channels are provided to use physical channels as a common resource, thereby realizing collision avoidance and a collision solution algorithm with improved performance. CONSTITUTION: If power is applied to a type-2 node, a pulse generation unit(420) outputs a pulse at an output time of an initially effective peak waveform at each predetermined cycle in case of output of a preamble detection unit(410). A generated pulse row(403) and a self-running clock are provided as input of a PLL(Phase Locked Loop)(430). The PLL generates stable preamble transmission time. If output of the PLL is stabilized in the type-2 node, the type-2 node starts preamble transmission.
