|Title:||SIGNAL TRANSMISSION METHOD AND DEVICE|
The application discloses a signal transmission method and device. The signal transmission method comprises: a first communication node determining a mode for transmitting data in a time unit to a second communication node; and the first communication node transmitting data to the second communication mode in the first time unit according to the determined mode for transmitting data. The data includes N data sets, where N is a positive integer. A data transmission method for M data sets in the data is known to the second communication node. Related information of a data transmission method for (N-M) data sets is indicated to the second communication node by the first communication node by means of a control signal in the time unit, where M is less than or equal to N.
