Abstract: In a communication method, a base station may use a wake-up signal (WUS) to carry an indication indicating a cell managed by the base station. A terminal device in a non-connected state receives the WUS, and this indicates that the terminal device is in a coverage area of the cell indicated by the indication. Then, the terminal device may listen to paging or initiate random access in the cell. According to the method, the terminal device in the non-connected state may determine, by using the WUS, whether the terminal device is still in a coverage area of a cell on which the terminal device previously camps, to implement mobility management. Further, after receiving the WUS, the terminal device in the coverage area of the cell indicated by the indication included in the WUS may listen to paging or initiate random access in the cell.

Abstract: A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

Abstract: The present disclosure relates to methods and terminal devices for detecting a wake-up signal. A terminal device sends first information to a network device, where the first information indicates a reported gap, receives second information sent by the network device, and determines a configuration condition of a first gap and a configuration condition of a second gap based on the second information. The terminal device determines a target gap based on the reported gap, the configuration condition of the first gap, and the configuration condition of the second gap, and detects a wake-up signal at a detection position before a start position of the first paging opportunity in a paging time window, where the detection position is determined based on the target gap and maximum duration of the wake-up signal.

Abstract: The present disclosure relates to wireless communications technologies, and in particular, to a network device, user equipment, and a system information transmission method. In embodiments of the present disclosure, for user equipments of different coverage grades within a coverage area of a cell, a network device uses different sending parameters to send pieces of system information. When receiving a piece of system information, user equipment first determines a coverage grade of the user equipment within the cell, and receives, in a receiving manner that matches a sending parameter used by the network device to send the system information at the determined coverage grade to which the user equipment belongs, the system information sent by the network device. The network device uses different sending parameters for different coverage grades. This ensures receipt of pieces of system information by user equipments belonging to different coverage grades.
