Abstract: A resource determining method includes that a first terminal obtains transmission information from a second terminal, wherein the transmission information is used to indicate a first sidelink resource. The first terminal determines a second sidelink resource according to the transmission information, wherein a time range of the second sidelink resource does not overlap that of the first sidelink resource. The first terminal sends a first data to the second terminal on a sidelink resource of the second sidelink resource, wherein the first sidelink resource comprises a sidelink resource on which a second data is received by the second terminal.

Abstract: This application discloses a communication method and apparatus. In embodiments of this application, when a terminal device in a sleep state needs to send a scheduling request or a negative acknowledgement (NACK), the terminal device enters a wake-up state. The terminal device can receive, within a sleep time period, a physical downlink control channel that schedules a resource for the scheduling request or the NACK, without waiting for the sleep time period to end before receiving the physical downlink control channel. Therefore, power consumption of the terminal device is reduced, while it is still ensured that certain physical downlink control channel is received as early as possible, thereby reducing a delay of the physical downlink control channel.

Abstract: This application provides a communication method and apparatus. The method includes: receiving, in a first control resource set or a second control resource set, first signaling from the network device, and adjusting the second control resource set based on the first signaling, where the first signaling indicates a quantity of symbols occupied by the second control resource set. Signaling that indicates a quantity of symbols of a CORESET is sent in a control resource set (for example, the first control resource set or the second control resource set). This helps implement flexible indication of a CORESET resource, so that a service requirement can be more quickly matched, and user experience can be improved.
