“…Para atender a estas rigorosas exigências e lidar com o au-mento da necessidade de banda dos servic ços de multimídia, a quinta geração (5G) de redes móveis sem fio tem sido apontada como uma alternativa viável em estudos de diversas áreas [Tang et al 2016]. Como exemplo de serviços a serem beneficiados pelas vantagens decorrentes da adoção do 5G, podem-se citar os seguintes:…”

“…Com o intuito de lidar com estes desafios, as redes 5G baseiam-se no desenvolvimento de novas técnicas que possibilitem um uso do espectro mais eficiente, permitindo que mais dispositivos utilizem o espectro simultaneamente. Neste contexto, espera-se que o emprego de antenas full-duplex possua um papel fundamental nas redes móveis operando sobre 5G [Tang et al 2016] [Zhang et al 2015]. O uso de antenas full-duplex apresenta diversas vantagens quando comparado com antenas half-duplex.…”

“…Entretanto, quando contrapostas com as antenas half-duplex, as antenas full-duplex possuem maior taxa de perda de pacote, menor confiabilidade do enlace e requerem uma fila maior para processar os pacotes recebidos [Zhang et al 2016]. Além disso, as antenas full-duplex sofrem dos efeitos da autointerferência, isto é, a interferência percebida na antena quando esta está em um mesmo momento transmitindo e recebendo algum sinal [Zhang et al 2015] [Tang et al 2016] . Para contornar as limitações resultantes da autointerferência, diversas técnicas da camada física foram projetadas tornando o uso de antenas full-duplex viável [Zhang et al 2015] [Murad and Eltawil 2017].…”

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%.

“…D2D users can effectively reuse the wireless resources authorized by the network to enhance the reusage rate of the wireless spectrum and expand the throughput and coverage of heterogeneous cellular networks [6,7]. In full duplex mode, the spectrum benefit is doubled as a result of allowing users to synchronize and send and receive signals simultaneously [8,9]. This technology can greatly improve the wireless transmission rate, and it has great technical advantages and application prospects.…”

Although the Device-to-Device (D2D) technology in cellular networks can improve the performance of cellular systems, it creates a large amount of interference in traditional communications. In this paper, the problem of resource allocation and control in a single-cell scene is studied. First, the concept of a restricted D2D communication area and a restricted D2D user-reusage area is put forward to reduce the complexity and interference intensity of resource allocation. Second, under the premise of satisfying the QoS (Quality of Service) demands of every system user, the resource allocation algorithm is improved, the optimal allocation of resources is carried out, and the algorithm’s processes are given in detail. Our simulated experiments show that the proposed method greatly improves the spectrum efficiency and the system fairness.

“…Existing and future services may have rigorous requirements for mobile network in terms of latency (round-trip time less than 10 ms), throughput surpassing 5 Gb/s, and density up to 900 Gb/s/km 2 [1]. To support these requirements and the increase of bandwidth-intensive multimedia services, the fifth-generation (5G) mobile wireless networks are being subject of intensive research in a wide number of areas [2]. Examples of services that may take advantage of the foreseeable 5G include Internet of things (IoT), vehicular networking, and mobile cloud computing [1].…”

The increasing demands for high-data rate traffic stimulated the development of the fifth-generation (5G) mobile networks. The envisioned 5G network is expected to meet its challenge by devising means to further improve spectrum usage. Many alternatives to enhance spectrum usage are being researched, such as massive MIMO, operation in mmWave frequency, cognitive radio, and the employment of full-duplex antennas. Efficient utilization of the potential of any of these technologies faces a set of challenges related to medium access control (MAC) schemes. This work focuses on MAC schemes tailored for full-duplex antennas, since they are expected to play a major role in the foreseeable 5G networks. In this context, this paper presents a MAC layer technique to improve total transmission time when full-duplex antennas are employed. Several evaluations in different scenarios are conducted to assess the proposed MAC scheme. Numerical results show that the proposed scheme provides gains up to 156% when compared to a state-of-the-art full-duplex antenna MAC protocol. Compared to traditional half-duplex antenna MAC protocols, the proposed scheme yields gain up to 412%.
