1. A method for a relay terminal to transmit and receive signals in a wireless communication system, the method comprising:
transmitting, in a first time region, a UL signal to an upper node through a backhaul link and a DL signal to at least one lower node through an access link; and
receiving, in a second time region, a DL signal from the upper node through the backhaul link and a UL signal from the at least one lower node through the access link,
wherein different frequency resources are allocated to the UL signal and the DL signal in the same carrier in each of the first time region and the second time region, and
wherein the backhaul link and the access link are side links (SLs).
