A communication method in a wireless communication system includes receiving, by a resonator unit of a first signal transfer apparatus, a wireless signal transmitted from a transmission apparatus, acquiring resonance energy from the wireless signal using at least one of a matcher unit and the resonator unit of the first signal transfer apparatus, transferring the wireless signal to one end of a transmission line via the matcher unit of the first signal transfer apparatus using the acquired resonance energy, transferring the wireless signal to a second signal transfer apparatus connected to an opposite end of the transmission line, and transmitting the wireless signal to a reception apparatus having a wireless link established with the second signal transfer apparatus using a matcher unit and a resonator unit of the second signal transfer apparatus.
