Abstract: 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.

Abstract: This application provides a method that includes the step of receiving, by a first device in a first time domain position, first scheduling information. The first scheduling information includes first indication information sent by a network device, wherein the first indication information is used to indicate a first interval. The method further comprises sending, by the first device, second scheduling information including second indication information to a second device in a second time domain position, wherein the second indication information is used to indicate a second interval, which is the difference between the first interval and a third interval. The second scheduling information is used by the second device to determine the target time domain position used by the second device to determine a time domain resource used to send and/or receive data.
