Abstract

Las modalidades de esta solicitud se refieren al campo de las comunicaciones y divulgan un método de comunicación y un aparato de comunicación, para reducir una tasa de error de bits y mejorar el rendimiento de recepción en un escenario en el que un canal inalámbrico cambia rápidamente. El método de comunicación y el aparato de comunicación pueden aplicarse a la Internet de los vehículos, por ejemplo, V2X, LTE-V y V2V. El método incluye: Un primer aparato terminal determina un factor de escala basado en un espaciamiento de subportadora de un primer recurso de tiempo-frecuencia que se utilizará para enviar los primeros datos y/o una cantidad de ranuras ocupadas por el primer recurso de tiempo-frecuencia. Los primeros datos son datos a enviar del primer aparato terminal, y el primer recurso de tiempo-frecuencia ocupa una ranura simple o una pluralidad de ranuras consecutivas. A continuación, el primer aparato terminal determina, basándose en el factor de escala, el tamaño de un bloque de transmisión que transporta los primeros datos, y envía el bloque de transmisión que transporta los primeros datos a un segundo aparato terminal en el primer recurso de tiempo-frecuencia.
