Abstract: Embodiments of this application provide a sidelink communication method and an apparatus. The method includes: When a first terminal device (a transmitting end) has to-be-sent first data or first signaling, the first terminal device first determines whether the first data or the first signaling supports multicast or broadcast SL DRX. When the first data or the first signaling supports multicast or broadcast SL DRX, the first terminal device obtains an SL resource corresponding to multicast or broadcast SL DRX, and sends the first data or the first signaling by using the SL resource corresponding to multicast or broadcast SL DRX. Therefore, it can be ensured that the receiving end terminal device can successfully receive the first data or the first signaling that supports multicast or broadcast SL DRX, thereby improving SL communication quality.

Abstract: This application discloses a routing method and an apparatus. The method and the apparatus may be used in a multi-hop communication scenario, and may also be used in another scenario. Particularly, the method and the apparatus are used for implementing routing between an AN device and remote UE in the multi-hop communication scenario. In the method, a relay terminal on a communication link may determine a transmission object by using route indication information of a data packet, or the route indication information and a target device identifier that are of the data packet, to transmit data carried in the data packet to the transmission object. In the method, routing transmission of the data packet may be guided by using route guide information, to ensure that the routing between the AN device and the remote UE can be implemented in the multi-hop communication scenario.

Abstract: A communication method and an apparatus. A terminal device determines height information, where a first parameter is related to the height information. The terminal device receives configuration information from a first network device, where the configuration information includes a correspondence between the height information and the first parameter. The terminal device determines, based on the height information, the first parameter corresponding to the terminal device. The first parameter includes one or more of a tracking area parameter, a radio access network notification area parameter, a cell selection or reselection parameter, and a measurement configuration parameter. Configuration information corresponding to a height of an uncrewed aerial vehicle is provided, to ensure that an uncrewed aerial vehicle terminal device at a high height obtains an effective configuration parameter, so that user experiences at different heights is improved.
