Abstract: This application discloses a signal transmission method and a related device. The method may include: sending, by a first terminal, a first message to a network device, where the first message is used to indicate a transmission mode used by the first terminal to transmit a signal; receiving a second message sent by the network device, where the second message is used to indicate a resource used by the first terminal to transmit the signal; and transmitting the signal on the resource. According to the foregoing solution, a terminal may transmit a signal by using different transmission modes and resources.

Abstract: Embodiments of the present invention provide a resource selection method, including: determining, by a first terminal, at least one of second parameter information of a second terminal and configuration information; and determining, by the first terminal, a target threshold based on at least one of the configuration information, the second parameter information, and first parameter information of the first terminal, where the target threshold is used by the first terminal to perform resource selection. The embodiments of the present invention further provide a resource selection apparatus. In the present invention, a resource is selected by changing a target threshold based on different parameters. In this way, a signal-to-interference ratio is increased, an error rate is reduced, and a demodulation performance is improved.
