Abstract: This application provides a terminal apparatus and method for discontinuous reception (DRX) in an unlicensed band, and may be applied to a scenario in which a terminal device performs communication through a sidelink or a Uu link. A signal receive end monitors a sidelink signal and/or a downlink signal on a grant-free resource configured by a network device, and switches between a non-DRX mode and a DRX mode when a corresponding preset condition is met. Alternatively, a transmit end directly indicates a receive end to use a DRX mode or a non-DRX mode, or indirectly indicates, with assistance of a network device, a receive end to use a DRX mode or a non-DRX mode. In this way, DRX of the receive end can be implemented in a sidelink unlicensed band or a Uu link unlicensed band. This reduces power consumption of the receive end.

Abstract: This application provides example signal transmission method and apparatus. One example method includes sending, by a first terminal device to a second terminal device, indication information indicating a signal transmission resource. Listen before talk (LBT) is performed by the first terminal device before transmission with the second terminal device is performed. Transmission with the second terminal device is performed by the first terminal device according to the indication information.
