The present invention is a base station device that is among the plurality of remote devices, comprising a plurality of remote devices, and the host device that carries the mobile communication signal to the main unit and the wireless carrier for processing a mobile communication signal through to the optical transmission line and with the host device according to a plurality of remote devices between the light transmission delay compensation method in a synchronous mobile communication system using a synchronous digital hierarchy transmission, the main device and the plurality of remote devices periods and the host device for each of the light transmission delay compensation test a plurality of a first process of forming a loop by using the optical transmission line between at least one of the remote device, the host device is transmitted to the remote device of the test through the loop the test synchronous digital hierarchy frames for the synchronous digital hierarchy for the test second process feedback receiving the frame, and a third process in which the host device measures the signal delay time of due to the optical transmission line by using the feedback test synchronous digital hierarchy frame for receiving, in the host device and the plurality of remote devices each test using synchronous digital hierarchy frame transmission delay time of a measurement for each of between about comprises a fourth step of adjusting the phase of the mobile communication signal transmitted from the host device to the remote device. ; Synchronous mobile communication system, a base station device, a synchronous digital hierarchy, the test pattern
