This paper made research to boost reception performance in link-down transmission method of LTE system, which is the next-generation mobile communication technology standard underway in 3GPP. To this end, it proposed installing relay (RS) in between station(BS) and terminal(MS), set the distance between BS and RS at 500m and 1,000m, each, and chose OFDMA and SC-FDMA as transmission method of RS. The paper found SC-FDMA to be better choice in RS when it is closer to BS and OFDMA to be a better choice in RS when the distance between BS and RS is farther. The system’s reception performance improved when the most appropriate transmission method fitting the circumstances was used in the middle between BS and MS.
