The thought of non-orthogonal multiple access (NOMA) are given as a potential radio access method for versatile correspondence networks past the fourth era (4G). As opposed to current long haul development radio access procedures, non-symmetrical different access involves the power space for client multiplexing at the transmitter and utilizations a successive obstruction dropping recipient as the pattern collector conspire, considering future cell phone advancement. Non-symmetrical different access is feasible to serve various clients simultaneously and recurrence. For 5G wireless communication networks, non-orthogonal multiple access (NOMA) and millimeter wave (mm-Wave) communications are interesting technologies. The performance of partially connected hybrid beamforming (PC-H-BF), a low-cost partially connected hybrid beamforming (H-BF) with a quick convergence sub-optimal power allocation algorithm, was explored in this work. A low-cost hybrid beam forming technique, as well as a dynamic threshold users' grouping mechanism, were created. In addition, to boost information flow, the sub-optimal inert-beam and intra-beam dynamic power allocation tasks are implemented using a low-complexity iterative maximization technique.
