Abstract—In this paper, new radio access scheme that combining relaying protocol and Non-orthogonal Multiple access (NOMA) system is introduced. In particular, different scenarios for fixed power allocation scheme are investigated. In addition, the outage probability of both weak and strong user is derived and provided in closed-form expressions. Such outage is studied in high SNR scenario and comparison performance between these NOMA scenarios is presented. Numerical simulations are offered to clarify the outage performance of the considered scheme if varying several parameters in the existing schemes, and to verify the derived formula.
