Abstract

The present disclosure provides a data transmission method and a communications device. The method includes: determining a first transmission manner of a first physical channel, where the first transmission manner is a manner in which data transmission is performed on the first physical channel; and determining a second transmission manner of a second physical channel according to the first transmission manner, where the second transmission manner is a manner in which data transmission is performed on the second physical channel. It is implemented that a transmission manner of a physical channel different from the first physical channel is determined according to the transmission manner of the first physical channel, and therefore it is implemented that different transmission manners are applied to different channels.
