The ever-increasing demand for data traffic for future wireless systems poses challenging requirements for 5G wireless communications, such as high spectral efficiency, better interference management, and extensive connectivity. These challenges open the possibility to use non-orthogonal multiple access (NOMA) schemes in future radio access networks. In these schemes, the users are multiplexed in power domain in the transmitter and de-multiplexed using successive interference cancellation in the receiver. In this work, we propose a hybrid resource allocation technique which consists of orthogonal and non-orthogonal radio resources and also study the improvements on cell capacity achieved in several proposed cases. To this end, we use millimeter-wave (mmWave) based single-cell deployment to evaluate the performance of this hybrid scheme.
