Abstract
A wireless communication system comprises a relay system including a plurality of relay devices and a plurality of wireless terminal devices. Each relay device transmits control information to the wireless terminal device which is registered in the own relay device, and each wireless terminal device selects, based on the control information received from the relay device which registers the own wireless terminal device, a channel which is currently able to relay a communication among channels respectively allocated to the relay devices to establish a communication between the wireless terminal devices. Each relay device acquires information configuring the control information via a communication line and causes a downlink signal wirelessly transmitted by the own relay device to synchronize with a communication signal, and each wireless terminal device maintains, when shifting a channel for communication to another channel, a synchronized state established in a channel prior to shifting.
