Wireless communication system, wireless communication method, and storage medium of the system

Abstract

In a wireless communication system including a plurality of wireless base stations, the wireless base stations other than the uppermost wireless base station among the plurality of wireless base stations each determine a frame timing on the basis of synchronization timing information received from the upper wireless base station, and the wireless base stations other than the lowermost wireless base station among the plurality of wireless base stations each notify the lower wireless base station of the synchronization timing information. A communication path from the uppermost wireless base station to the lowermost wireless base station includes a branch point and a merge point, and a junction base station that is the wireless base station installed at the merge point measures a synchronization error between a priority synchronization path and a non-priority synchronization path different from the priority synchronization path, the priority synchronization path being one of a plurality of the communication paths from the branch point to the merge point. Each of the plurality of wireless base stations installed on the non-priority synchronization path adjusts the frame timing on the basis of the synchronization error.
