Este artigo avalia uma variedade de tecnologias 5G importantes, como antenas massivas de estação base (BS), múltiplas entradas e múltiplas saídas (MIMO), formação de feixe e rastreamento, transferência de unidade intra-banda base (BBU) (HO) e cobertura. Isso é feito em diferentes áreas 5G interessantes com uma variedade de condições de rádio, como um saguão interno de um prédio de escritórios, uma área de estacionamento externa e uma implantação urbana realista de um sistema de acesso de rádio 5G com BSs instalados em edifícios para implantar uma área de teste 5G em a área à beira-mar de Tóquio Odaiba. Resultados experimentais mostram que a taxa de transferência superior a 10 Gbps é alcançada em uma largura de banda de 730 MHz usando 8 portadoras componentes, e o ganho de taxa de transferência MIMO distribuído é alcançado em várias implantações de pontos de transmissão no saguão interno do prédio de escritórios e na área de estacionamento externa usando duas unidades de rádio (RUs). Em particular, na área de estacionamento exterior, espera-se uma vantagem distinta do MIMO distribuído e é alcançado um ganho de rendimento de 60% do MIMO distribuído. Os resultados experimentais também esclarecem o desempenho do downlink em uma implantação urbana. Os resultados experimentais mostram que a taxa de transferência superior a 1.5 Gbps é alcançada na área e aproximadamente 200 Mbps é alcançada a 500 m de distância da BS. Também confirmamos que o rastreamento de feixe e o HO intra-BBU funcionam bem, compensando a alta perda de caminho em 28 GHz e alcançando cobertura a 500 m do BS. Por outro lado, as condições de linha de visão (LoS) e sem linha de visão (N-LoS) são críticas para o desempenho do 5G na banda de 28 GHz, e observamos que as conexões 5G às vezes são deixadas atrás de árvores, edifícios, e sob passarelas.

Abstract: This paper evaluates a variety of key 5G technologies such as base station (BS) massive multiple-input multiple-output (MIMO) antennas, beamforming and tracking, intra-baseband unit (BBU) hand over (HO), and coverage. This is done in different interesting 5G areas with a variety of radio conditions such as an indoor office building lobby, an outdoor parking area, and a realistic urban deployment of a 5G radio access system with BSs installed in buildings to deploy a 5G trial area in the Tokyo Odaiba waterfront area. Experimental results show that throughput exceeding 10Gbps is achieved in a 730MHz bandwidth using 8 component carriers, and distributed MIMO throughput gain is achieved in various transmission point deployments in the indoor office building lobby and outdoor parking area using two radio units (RUs). In particular, in the outdoor parking area, a distinct advantage from distributed MIMO is expected and the distributed MIMO gain in throughput of 60% is achieved. The experimental results also clarify the downlink performance in an urban deployment. The experimental results show that throughput exceeding 1.5Gbps is achieved in the area and approximately 200 Mbps is achieved at 500m away from the BS. We also confirm that the beam tracking and intra-BBU HO work well compensating for high path loss at 28-GHz, and achieve coverage 500m from the BS. On the other hand, line of sight (LoS) and non-line-of sight (N-LoS) conditions are critical to 5G performance in the 28-GHz band, and we observe that 5G connections are sometimes dropped behind trees, buildings, and under footbridges.
