Abstract

MÉTODO E APARELHO DE TRANSMISSÃO PARA SISTEMA MIMO. Uma técnica de comunicação para convergência entre uma tecnologia de IoT e um sistema de comunicação de quinta geração (5G) para suportar uma taxa de transmissão de dados mais alta que a de um sistema de quarta geração (4G), e um sistema da mesma é fornecido. O método inclui serviços de inteligência (por exemplo, casas inteligentes, edifícios inteligentes, cidades inteligentes, carros inteligentes ou carros conectados, cuidados de saúde, educação digital, negócios de varejo, serviços relacionados com proteção e segurança e semelhantes). Com base em uma tecnologia de comunicação 5G e uma tecnologia relacionada com IoT. Um método inclui determinar um parâmetro relacionado com escalonamento para pelo menos um usuário, e transmitir informação de escalonamento indicando o parâmetro relacionado com escalonamento para uma unidade de rádio (RU), em que a informação de escalonamento inclui um primeiro campo de extensão de seção incluindo informação se relacionando com um identificador de equipamento de usuário (ueID) relacionado com pelo menos um usuário, e um segundo campo de extensão de seção incluindo informação se relacionando com um número de ueIDs correspondendo a cada usuário.
