O sistema de comunicação móvel de quinta geração (5G) está sendo pesquisado e desenvolvido para lançamento como serviço comercial em 2020. A rede móvel 5G incluirá muitas tecnologias de acesso via rádio, como LTE, 5G NR e WLAN. Portanto, um equipamento de usuário (UE) estará conectado a diferentes tipos de estações base à medida que se move dentro de uma rede 5G heterogênea. Conseqüentemente, presume-se que o rendimento mudará com cada mudança na célula servidora. A rede móvel 5G deverá servir conteúdos de grande capacidade, como vídeos em 4K. No entanto, um método convencional de streaming de vídeo não pode utilizar eficazmente a largura de banda disponível numa rede 5G heterogénea. Neste estudo, propomos um método de adaptação da taxa de envio baseado em previsões para a largura de banda disponível. No método proposto, a largura de banda disponível é prevista a partir dos dados de registro de comunicação. A base de dados de registo de comunicação, incluindo o rendimento passado com a sua localização, é criada por um UE. Um UE refere-se aos dados de registro de comunicação para previsões de quando a célula de serviço provavelmente mudará. Desenvolvemos um dispositivo de streaming de vídeo que implementa o método proposto e avalia seu desempenho. Os resultados mostram que o método proposto pode alterar a taxa de envio e a resolução de acordo com a largura de banda disponível. O método proposto aumenta a probabilidade de transmissão de vídeo de alta resolução, o que não é possível com métodos convencionais. Além disso, realizamos avaliação subjetiva do vídeo transmitido pelo teste de prova de conceito. O resultado da avaliação subjetiva mostra que o método proposto melhora a qualidade da experiência de streaming de vídeo.

Abstract: The fifth-generation (5G) mobile communication system is being researched and developed for launch as a commercial service in 2020. The 5G mobile network will include many radio access technologies, such as LTE, 5G NR, and WLAN. Therefore, a user equipment (UE) will be connected to different types of base stations as it moves within a 5G heterogeneous network. Accordingly, it is assumed that the throughput will change with each change in the serving cell. The 5G mobile network is expected to serve large capacity contents, such as 4K videos. However, a conventional video streaming method cannot effectively use the available bandwidth in a 5G heterogeneous network. In this study, we propose a sending rate adaptation method based on predictions for the available bandwidth. In the proposed method, the available bandwidth is predicted from the communication log data. The communication logging database, including past throughput with its location, is created by a UE. A UE refers to the communication log data for predictions when the serving cell is likely to change. We develop a video streaming device that implements the proposed method and evaluates its performance. The results show that the proposed method can change the sending rate and resolution according to the available bandwidth. The proposed method increases the probability of transmitting high-resolution video, which is not possible with conventional methods. Moreover, we performed subjective evaluation of the transmitted video by the proof-of-concept test. The result of the subjective evaluation shows that the proposed method improves the quality of experience for video streaming.
