A method includes that a first terminal device sends a sidelink discontinuous reception (DRX) parameter of a second terminal device or indication information to a network device such that the network device determines a first time period based on the sidelink DRX parameter or the indication information, where the first time period belongs to sidelink DRX active time of the second terminal device. The first terminal device receives a sidelink grant sent by the network device, where the sidelink grant is used to indicate the first terminal device to send a resource of a physical sidelink control channel (PSCCH) and/or a physical sidelink shared channel (PSSCH), and a time domain position of the resource is in the first time period. The first terminal device sends a PSCCH and/or a PSSCH based on the sidelink grant.

In embodiments of this application, a network device may indicate the at least one periodicity to the terminal device, so that the terminal device can detect the downlink signal based on the at least one periodicity. For example, the at least one periodicity matches a state of the network device. This is equivalent to describing that the terminal device can detect the downlink signal based on the state of the network device, to reduce power consumption of the terminal device as much as possible.
