Abstract: An information transmission method. A terminal device receives first indication information for monitoring combination from a network device. The first indication information for monitoring combination is usable to indicate at least two candidate monitoring behaviors. The terminal device receives downlink control information DCI from the network device. The DCI is usable to indicate a monitoring behavior of the terminal device. The monitoring behavior is one of the at least two candidate monitoring behaviors. The terminal device performs a downlink control channel PDCCH monitoring behavior based on the first indication information for monitoring combination and the DCI.

Abstract: A communication method and apparatus to improve flexibility of performing PDCCH monitoring by a terminal device, and reduce power consumption of the terminal device. According to the method, in a dynamic SS set group switching mechanism, the terminal device may alternatively not perform PDCCH monitoring on some monitoring occasions corresponding to an SS set in a monitoring state, to improve the flexibility of performing PDCCH monitoring by the terminal device, and overcome a power consumption waste caused by unaligned monitoring occasions corresponding to different SS sets.

Abstract: A method for indicating to skip PDCCH monitoring and an apparatus are provided, to indicate, by using downlink control information, a terminal device to skip PDCCH monitoring. After a network device sends DCI that includes PDCCH skipping indication information to the terminal device, the terminal device determines, based on the PDCCH skipping indication information, not to monitor a PDCCH in a first time interval. In this way, the DCI is used to indicate the terminal device to skip PDCCH monitoring, and specific signaling used to indicate to skip PDCCH monitoring is clarified, thereby saving energy of the terminal device.

Abstract: A wake-up signal detection method and an apparatus are provided, and are applicable to fields such as V2X, the internet of vehicles, an intelligent and connected vehicle, assisted driving, and intelligent driving. The method includes: determining, by a terminal device, N PDCCH monitoring occasions before an active time DRX ON; and detecting a wake-up signal WUS on M of the N PDCCH monitoring occasions, where M is less than N, and both N and M are positive integers greater than 1. The wake-up signal WUS is detected by using the method, so that power consumption of the terminal device can be effectively reduced, and a power saving gain can be improved.

Abstract: This application discloses a communication method and apparatus. A terminal device receives first information from a network device. The first information indicates that the terminal device is to skip PDCCH blind detection. The terminal device determines a start moment of a first time period based on the first information. The terminal device stops the PDCCH detection within the first time period from the start moment of the first time period. The terminal device determines a time from which the PDCCH detection is actually stopped, so that the network device and the terminal device can have consistent understanding for the time from which the terminal device actually stops the PDCCH detection, to improve resource utilization and reduce power consumption of the terminal device.

Abstract: This application provides example communication methods and apparatuses. One example method includes performing, by a network device on a preconfigured resource, data demodulation on uplink data from a terminal device. The network device can then send downlink control information (DCI) to the terminal device, where the DCI includes first indication information, and if the uplink data fails to be demodulated, or it is determined, based on a result of the data demodulation, that the terminal device needs to retransmit the uplink data, the first indication information indicates either the terminal device to initiate random access or EDT and retransmit the uplink data or that the uplink data fails to be demodulated.
