- Disclosed is a method for applying non-orthogonal multiple access in a multi-hop relay system constituted by a base station, a relay, a first user terminal, and a second user terminal, including: receiving, by the first user terminal, a first data signal which the first user terminal needs to receive and a second data signal which the second user terminal needs to receive from the base station through a first phase; receiving, by the first user terminal, a third data signal from the base station through a second phase when the second data signal is relayed through the second phase by the relay; and removing an interference signal included in the third data signal received through the second phase by using the second data signal which the first user terminal receives through the first phase.
