Abstract

MÉTODO DE TRANSMISSÃO DE DADOS E APARELHO RELACIONADO. Este pedido fornece um método de transmissão de dados e um aparelho relacionado. O método inclui: Um dispositivo de rede gera uma primeira unidade de dados de protocolo de camada física PPDU. A primeira PPDU inclui um primeiro campo de sinalização universal campo U-SIG e um primeiro campo de sinalização de rendimento extremamente alto campo EHT-SIG, uma soma de uma quantidade de bits de informação do primeiro campo U-SIG e uma quantidade de bits de informação do primeiro campo EHT-SIG é menor que ou igual a 78 bits de informações, e pelo menos um do primeiro campo U-SIG e o primeiro campo EHT-SIG incluem um campo de indicação de identificador, em que o campo de indicação de identificador é usado para identificar de forma única uma estação. O dispositivo de rede envia uma primeira PPDU codificada para uma estação. Dessa forma, overheads de indicação podem ser reduzidos, e o primeiro campo U-SIG e o primeiro campo EHT-SIG podem portar mais informações. Modalidades deste pedido podem ser aplicadas a um sistema de rede de área local sem fio suportando um protocolo de próxima geração Wi-Fi EHT do IEEE 802.11, isto é, protocolos 802.11 tais como 802.11be.
