Abstract: Embodiments of the present disclosure disclose example network device, terminal device, and method for notifying information about a power difference. One example network device includes one or more processors performing operations that include determining first information and sending, by a transceiver of the network device, the first information to a terminal device. The first information indicates a first power difference that is associated with a first waveform. The first power difference is an offset between a power of a reference signal and a power of a first physical downlink shared channel (PDSCH) on which the first waveform is used.

Abstract: This application provides a service transmission method. The method includes: sending, by a first node, a route request to a second node at a first moment, where the route request is used to request a routing path for at least one service; receiving, by the first node, a route response message at a second moment, where the route response message includes a route distinguisher, and the route distinguisher is used to indicate the routing path; and determining, by the first node based on a time interval between the first moment and the second moment, a target service that is in the at least one service and that is served by the routing path. In this way, the first node may determine, based on duration of the time interval between the first moment and the second moment, the target service that can be served by the routing path.

Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.
