Title: COMMUNICATION SYSTEM, TERMINAL DEVICE, AND COMMUNICATION METHOD
Abstract:
A bi-directional communication method needs to be switched on the basis of bi-directional communication cost. The present invention provides a communication system formed of a first terminal device and a second terminal device. The first terminal device is provided with a radio unit that transmits a first signal by using a first communication path, which is a direct communication path to the second terminal device. The second terminal device is provided with a radio unit that transmits a second signal by using a second communication path, which is a communication path different from the first communication path. The first terminal device transmits the first signal on the basis of a feature value of the second signal transmitted by the second terminal device.
