In this paper, an alternative hybrid infrastructure to complete the media cellular TV puzzle called 5G broadcast is introduced and developed. The performance of a non-orthogonal and orthogonal physical hybrid layer for cellular broadcasting is investigated. A downlink layered division multiplexing with non-orthogonal multiple access (LDM-NOMA) together with a further evolved multimedia broadcast multicast service with orthogonal multiple access (FeMBMS-OMA) is superimposed. In our scenario, we have defined them as two broadcast service providers (BSPs), whereby the former recruits the latter as a cooperative layer. Service selection is done by using a binary factor access technology. We assume that there is perfect knowledge with channel state information for Rayleigh fading multipath channel. Bit error rate (BER) and outage/coverage capacity are selected as our inquiries stochastic geometry benchmarks. The spectrum constellations of the scheme are worked according to the resource block (RB) element/symbols and different modulations. The proposed framework can work without a subscriber identity module (SIM card) uplink and internet protocol (IP). Mathematical analysis, based on the exact closed-form expressions, is consistent with the theory of the proposed LDM-NOMA and FeMBMS-OMA. The simulation results are based on the Monte Carlo iterative methodology, and demonstrate the superiority of the hybrid framework compared to each of the technologies separately.
