No contexto do isolamento de recursos para fatiamento de rede, este artigo apresenta dois métodos de alocação de recursos especialmente para a parte da rede de acesso de rádio (RAN). Ambos os métodos podem ser implementados por meio de uma ligeira modificação do algoritmo de agendamento de pacotes comum, como o algoritmo de justiça proporcional, e garantem o isolamento de recursos limitando o número máximo de blocos de recursos (RBs) alocados para cada fatia. Além disso, uma vez que ambos os métodos alocam RBs de forma flexível para toda a largura de banda do sistema, há casos em que o desempenho da taxa de transferência é melhorado em comparação com quando a largura de banda do sistema é dividida de maneira estática, especialmente em um ambiente de canal seletivo em frequência. Os resultados numéricos mostram a superioridade desses métodos em relação à divisão simples da largura de banda do sistema de maneira estática e mostram a diferença entre as características dos métodos em termos de desempenho de rendimento de cada fatia.

Abstract: In the context of resource isolation for network slicing, this paper introduces two resource allocation methods especially for the radio access network (RAN) part. Both methods can be implemented by slight modification of the ordinary packet scheduling algorithm such as the proportional fairness algorithm, and guarantee resource isolation by limiting the maximum number of resource blocks (RBs) allocated to each slice. Moreover, since both methods flexibly allocate RBs to the entire system bandwidth, there are cases in which the throughput performance is improved compared to when the system bandwidth is divided in a static manner, especially in a frequency selective channel environment. Numerical results show the superiority of these methods to dividing simply the system bandwidth in a static manner, and show the difference between the features of the methods in terms of the throughput performance of each slice.
