Abstract: Embodiments of this application relate to a wake-up signal (WUS) detection method and apparatus, to reduce signaling overheads of a network side device. The WUS detection method is as follows: a terminal device detects a terminal device-specific field in a detected WUS. If the terminal device detects the terminal device-specific field in the WUS, and detects that the WUS includes wake-up information for the terminal device, the terminal device determines, by using location information of the terminal device-specific field as a first index, a first physical uplink control channel (PUCCH) resource corresponding to the first index, and sends a first PUCCH, where the first PUCCH includes a first message used to feed back that the wake-up information for the terminal device is received.

Abstract: A communication method and a communication apparatus are described. A network device explicitly indicates, by using indication information, a transmission priority of data that can be carried on a scheduled transmission resource. After receiving the indication information, a terminal device can determine whether data currently to be sent can be sent on the scheduled transmission resource, to reduce a probability of a communication failure caused by resource preemption in a scenario in which data of at least three transmission priorities coexists. The terminal device may further determine, based on the indication information, whether to-be-received data exists on the scheduled transmission resource.
