Abstract: PURPOSE: A broadband local wireless communication device and method thereof are provided to use both a detour link using a relay node to a communication between a source node and a target node and a direct line between the source node and the target node. CONSTITUTION: A control unit(720) determines a first time interval and a second time interval for cooperated data frame transfer by considering packet transmission time to a target node from a source node. A transfer unit(740) transmits a frame to the relay node through a directed antenna pattern which is desired to a relay node in a start point of the first interval. The transfer unit transmits the frame to the target node through an antenna pattern which is desired to the target node after a predetermined time has passed from a starting point of the second time interval.

Abstract: PURPOSE: A method and apparatus for time synchronization of distributed nodes over a wideband high frequency wireless system are provided to modify a MAC interface clock through the maximum operation offset among calculated operation offsets. CONSTITUTION: A MAC scheduler calculates an operation offset through the confirmation of a receiving node clock and a transmitting node clock(520), and stores the maximum operation offset by comparing calculated operation offset with the stored operation offset. If the completion of data reception is sensed, the MAC scheduler applies an RX_EN as 0(524). If the reception of a super frame is completed, the MAC scheduler modifies a MAC interface clock(528,530).
