Abstract

Esta solicitud proporciona un método y aparato de transmisión de unidad de datos de protocolo PPDU, y se relaciona con el campo de las tecnologías de comunicación, para indicar, a un STA, un canal para enviar una trama CTS. En el método, un primer dispositivo puede enviar una primera unidad de datos. La primera unidad de datos puede incluir al menos una segunda unidad de datos y una tercera unidad de datos. La segunda unidad de datos se usa para llevar una primera trama MU-RTS. La tercera unidad de datos se usa para llevar una segunda trama MU-RTS. La primera trama MU-RTS y la segunda trama MU-RTS usan un mismo valor de inicialización de código de codificación. Con base en la solución anterior, un AP puede indicar, una pluralidad de STA al usar una pluralidad de tramas MU-RTS, canales para responder a las tramas CTS. El AP puede indicar la primera trama MU-RTS y la segunda trama MU-RTS para usar el mismo valor de inicialización de código de codificación. Esto puede evitar un conflicto entre las diferentes tramas CTS.
