Abstract: A non-terrestrial network communication method includes: a terminal receives, from a first network device, a message indicating that a satellite that provides a service for a first cell is updated to a second satellite, where the first message includes information used to determine a coverage area of a second cell served by the second satellite on the ground. The terminal determines, based on a location of the terminal and the coverage area of the second cell on the ground, whether the terminal is located within or outside the coverage area.

Abstract: A terminal device receives a first system information change indication on a WUR link, and/or determines, on the WUR link, that a cell is changed, where the first system information change indication indicates that system information is changed. The terminal device receives the system information on an NR link if the system information is changed, before establishing or restoring a connection on the NR link. If the terminal device determines that the system information is not changed, the terminal device may not need to receive the system information. For example, the terminal device may directly establish or restore the connection on the NR link when the terminal device does not need to receive the system information.

Abstract: This application relates to a discontinuous reception method. In the first time unit, for example, the first symbol, after a hybrid automatic repeat request HARQ feedback occasion of a sidelink HARQ process, a first terminal may start a drx-HARQ-RTT-TimerSL and start a drx-RetransmissionTimerSL when the drx-HARQ-RTT-TimerSL expires. During running of the drx-RetransmissionTimerSL, the first terminal monitors a physical downlink control channel. In this way, sidelink retransmission efficiency can be improved, an increase of a sidelink retransmission delay can be avoided, and sidelink-based applications, such as unmanned driving, automatic driving, assisted driving, intelligent driving, networked driving, intelligent networked driving, and car sharing in the field of artificial intelligence can be better supported.

Abstract: A communication method and device are provided. A first message is received from a base-station central unit, where the first message is associated with determining whether a to-be-paged terminal device supports a first grouping manner and/or determining a paging manner for the to-be-paged terminal device. The terminal device is paged in a first paging manner that is determined based on the first message. A base-station distributed unit can determine, based on the first message, whether the to-be-paged terminal device supports a grouping manner or a grouping manner that can be supported by the to-be-paged terminal device. In this way, in a split architecture, the base-station distributed unit can also complete paging on the terminal device.
