Abstract This paper aims to realize a new multiple access technique based on recently proposed 5G communication. Integration of the presented reconfigurable antenna systems with the well-known non-orthogonal multiple access (NOMA) technique causes a significant degradation in sum rate due to the predictable power division in reconfigurable antennas. To circumvent this fundamental limit, a new multiple access technique is proposed. The integration of reconfigurable antenna systems with NOMA is a logical step in leveraging the capabilities of both technologies. The integration of reconfigurable antenna systems with NOMA is a logical step in leveraging the capabilities of both technologies. The technique which is called reconfigurable antenna non orthogonal multiple access (RA-NOMA) is proposed here. Three different cases are considered, i.e., OMA, RAMA-OMA and RA-NOMA with partial and full channel state information (CSI). In the first case, orthogonal multiple access is employed only. In second case RAMA is applied for OMA to enhance the performance of OMA. In the third case, RAMA with full CSI is applied to NOMA for both symmetric and asymmetric channels. All three cases are simulated in MATLAB environments. The simulation plots demonstrate the analytical findings.
