Abstract: This application provides a method for determining a sidelink DRX configuration and a communication apparatus. The method includes: determining at least two PQIs or sidelink QoS profiles corresponding to a service of a terminal, then determining at least two sidelink DRX configurations corresponding to the at least two PQIs or sidelink QoS profiles, and then determining a sidelink DRX configuration for use based on the at least two sidelink DRX configurations. In this way, an appropriate sidelink DRX configuration can be determined for use, to help improve efficiency of communication between terminals. In addition, when a terminal on a transmitter side and a terminal on a receiver side each determine a sidelink DRX configuration for use according to the method, both the terminal on the transmitter side and the terminal on the receiver side use a same sidelink DRX configuration.

Abstract: This application provides a communication method, and a communications apparatus. The communication method includes: An access network device sends a deactivation indication or an activation indication to a terminal. The deactivation indication is used to indicate that a primary secondary cell in a secondary cell group is in a deactivated state, and the activation indication is used to indicate that the primary secondary cell is in an activated state. The access network device is a master node or a secondary node of the terminal. In receiving the deactivation indication or the activation indication, the terminal performs a deactivation operation on the secondary cell group according to the deactivation indication, or activates the secondary cell group according to the activation indication.

Abstract: This application discloses a path switching method that includes: sending, by a first terminal, a first message to a first network device, where the first message is used to request to switch a second terminal from an indirect connection path for communicating with the first network device by using the first terminal to a direct connection path for communicating with the first network device or a second network device, or the first message is used to request to release a link between the first terminal and the second terminal, and the first network device is different from the second network device; and releasing, by the first terminal, the link between the first terminal and the second terminal. With this solution, a relay terminal can trigger switching of a remote terminal from an indirect connection path to a direct connection path, to adapt to a relay scenario more flexibly.
