Abstract
A relay-based data transmission approach to improve the reliability and/or the energy efficiency of uplink NOMA. A relay node (RN) is employed to improve the performance of both weak and strong UEs. In some embodiments, superposition coding and NOMA-based transmission are applied at the RN and the UEs, respectively, to improve the achievable rates of the UEs.
