Signal transmission method, first device, and second device

Abstract

The invention proposes a signal transmission method, a first device, and a second device. This method includes: configuring the first piece of information for the second device, where the first piece of information is used to indicate the transmission location and timing of the signal corresponding to the first signal resource and / or the first set of signal resources; and sending the first piece of information to the second device via signal. Therefore, according to the implementation options of the invention, the second test device transmits the corresponding signal based on the flexible scheduling of the first device, thereby improving the reliability and flexibility of signal transmission.
