Abstract

Esta solicitud proporciona un método y aparato de transmisión de información de control de capa física, para mejorar la fiabilidad de la transmisión de datos y reducir la latencia, y se refiere al campo de las tecnologías de comunicación inalámbrica. En el método, un primer aparato de comunicación puede obtener primera información de control de capa física. La primera información de control de capa física puede incluir N piezas de primera información, donde N es mayor o igual que 2. El primer aparato de comunicación puede obtener la primera información objetivo a partir de las N piezas de primera información. La primera información objetivo puede indicar un recurso de dominio de frecuencia de un primer canal. El primer aparato de comunicación puede estimar el primer canal con base en la primera información objetivo. El primer aparato de comunicación puede obtener segunda información de control de capa física. La segunda información de control de capa física incluye información de señalización que puede ser utilizada por el primer aparato de comunicación para enviar información de retroalimentación correspondiente al primer canal. El primer aparato de comunicación puede enviar la información de retroalimentación con base en la segunda información de control de capa física.
