Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/16744Next-generation wireless communication networks demand extremely high requirements with the increase in data traffic, user transmission rates, decrease in minimum transmission delay, and a massive number of wireless devices per unit area. To meet these demands, network densification, the development of new access technologies, and resource management are necessary. However, challenges associated with interference and resource allocation emerge as significant obstacles. Power allocation is identified as crucial to mitigate interference, ensure specific quality requirements for different services, and enhance spectral efficiency. This work applies a multi-objective algorithm for power allocation in a scenario that employs the Rate Splitting Multiple Access (RSMA) concept, an emerging alternative for next-generation networks. RSMA involves splitting messages into private and common parts, allowing adaptation of the amount of signal sent in an overlapping channel. Evaluation metrics include spectral efficiency, specifically the minimum rate among users, the Sum Rate (SR), and energy efficiency. The average results obtained are compared with NOMA (Non-Orthogonal Multiple Access), indicating gains of 11% in spectral efficiency and 2% in energy efficiency with the implementation of RSMA in the simulated scenario.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/RSMA (Diivisão de taxa de acesso múltiplo)Tecnologia 6GNOMA (Acesso múltiplo não ortogonal)RSMA (Rate splitting multiple access)NOMA (Non-orthogonal multiple access)DissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOESREDES E SISTEMAS DISTRIBUÍDOSCOMPUTAÇÃO APLICADA
