Abstract: 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.

Abstract: An inter-cell cooperative transmission-based transmission and reception method is provided. According to an exemplary embodiment, the inter-cell cooperative transmission-based transmission and reception method includes acquiring data of a terminal from a macro base station without exchanging data between small base stations in an environment where an exchange of cooperation-related information between the small base stations or between the small base stations and the terminal is limited; and transmitting the control information and the data, which are acquired by the small base stations, to the terminal in a cooperative manner among the base stations.
