ABSTRACT

In this letter, we propose a cooperative relaying system (CRS) combining orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) for uplink transmission. In the proposed system, cell-center user (CCU) amplifies and forwards the cell-edge user (CEU) signal to base station (BS), meanwhile transmitting its own signals by NOMA. This win-win operation drives CCU and CEU to work together, and is particularly useful when CCU holds good channel conditions to BS but lacks radio resources. Both analytical and asymptotic expressions of the outage probability are derived for CEU and CCU. Simulation results demonstrate the large performance gains achieved over the benchmark schemes, owing to the adoption of the proposed system.
