Document Type and Number:
WIPO Patent Application WO/2019/244633
Kind Code:
A1
Abstract:
In the present invention, a communication system transmits relay data through a communication path composed of multiple zones using different communication systems. A relay communication device is disposed between a first zone and a second zone which are adjoining zones. The relay communication device is provided with: a reception unit for receiving relay data from the first zone in the form of a frame of a first communication system; and a relay unit that outputs, to the second zone, a frame of a second communication system, which is used for transmitting the relay data to a relay destination, wherein the frame has set therein signal quality information which indicates signal quality calculated with respect to the physical link of each zone through which the relay data is transmitted before reaching the relay communication device.
