Full-duplex em banda (IBFD) tem sido uma tecnologia atraente, que pode, teoricamente, dobrar a eficiência espectral. No entanto, ao realizar IBFD no sistema celular duplex dinâmico (DDC), a interferência entre usuários (IUI) deteriora o desempenho de transmissão na comunicação downlink (DL) e limita a área aplicável ao IBFD e a taxa de aplicação do IBFD. Neste artigo, para expandir a área aplicável do IBFD e melhorar a taxa de aplicação do IBFD, propomos um esquema de redução de IUI usando cancelamento de interferência sucessivo (SIC) para o sistema DDC. O SIC pode utilizar a diferença de potência e reduzir o sinal com a potência mais alta. A eficácia do esquema proposto é avaliada pela simulação computacional. O efeito de redução da IUI na área inaplicável do IBFD é confirmado quando a potência recebida da IUI é mais forte que a do sinal desejado no equipamento do usuário para DL (DL-UE). A área inaplicável do IBFD dentro de 95m do DL-UE, onde o IBFD não funciona sem o esquema proposto, pode reduzir em 43.6%, de 52.8% para 9.2%, com a aplicação do esquema proposto. Além disso, a taxa de aplicação do IBFD pode melhorar em 24.6%, de 69.5% para 94.1%.

Abstract: In-band full-duplex (IBFD) has been an attractive technology, which can theoretically double the spectral efficiency. However, when performing IBFD in the dynamic-duplex cellular (DDC) system, inter-user interference (IUI) deteriorates transmission performance in downlink (DL) communication and limits IBFD-applicable area and IBFD application ratio. In this paper, to expand the IBFD-applicable area and improve the IBFD application ratio, we propose an IUI reduction scheme using successive interference cancellation (SIC) for the DDC system. SIC can utilize the power difference and reduce the signal with the higher power. The effectiveness of the proposed scheme is evaluated by the computer simulation. The IUI reducing effect on the IBFD-inapplicable area is confirmed when the received power of the IUI is stronger than that of the desired signal at the user equipment for DL (DL-UE). The IBFD-inapplicable area within 95m from the DL-UE, where the IBFD does not work without the proposed scheme, can reduce by 43.6% from 52.8% to 9.2% by applying the proposed scheme. Moreover, the IBFD application ratio can improve by 24.6% from 69.5% to 94.1%.
