FDT-MAC: Reduzindo a latência das comunicações full-duplex em redes móveis sem fio
Resumo
A crescente demanda por largura de banda impulsionou o estudo e o desenvolvimento da quinta geração (5G) de redes móveis. Espera-se que as redes 5G criem mecanismos que permitam uma melhoria no uso do espectro. Antenas full-duplex e técnicas de controle de acesso ao meio (MAC) tendem a ser fundamentais no panorama de redes 5G. Este trabalho propõe uma técnica MAC que reduz a latência da reserva de canal quando se considera o uso de antenas full-duplex. Resultados analíticos indicaram que a técnica proposta obteve ganhos de vazão de até 156% quando comparado com um protocolo do estado da arte projetado para comunicações full-duplex. Quando comparado com esquemas tradicionais half-duplex, o ganho de vazão superou 400%.
