Disclosed are a method and a device for signal transmission. The method includes: determining a transmission mode of a first signal according to at least one of the following: relationship information between a first spatial filtering parameter and a second spatial filtering parameter; a third reference signal associated with the second signal; relationship information between a first reference signal and a second reference signal; relationship information between DCIs corresponding to the first and the second signals; whether a time interval between the first and second signals being greater than predetermined threshold; information type of information in the first signal; time delay information required for switching the spatial filtering parameters; a configuration information indicating whether the first signal and the second signal share one spatial filtering parameter; and sending or receiving the first signal using the determined transmission mode.
