Performance Study of Downlink Users in Non- Orthogonal Multiple Access (NOMA) for 5G Communications
NOMA, 5G, Power allocation, Cooperative NOMA
An outline of NOMA principles is provided in this article Furthermore this page discusses cooperative NOMA and its variations explains power allocation in detail as a technique of resource allocation for NOMA and gives an overview of the research challenges related to NOMA We then use a two-case scenario to suggest a dynamic power allocation DPA plan for the downlink NOMA users albeit it can also be expanded to many use cases The DPA relies on channel state information CSI to guarantee the quality of service QOS for cell center customers user c The Outage probability OP as a critical performance criterion simulation data is also provided and they demonstrate a notable performance improvement when DPA is employed compared to fixed power allocation
