this paper, we study performance improvement
methods for a cell-edge user of two-user non-orthogonal multiple
access (NOMA) systems in downlink scenarios. To this end,
we propose two cooperative relaying schemes, namely on/offfull-
duplex relaying (on/off-FDR) and on/off-half-duplex relaying
(on/off-HDR) schemes. More specifically
