Abstract: A terminal device receives a reference signal from a first cell, where time domain resources occupied by the reference signal are fewer than total time domain resources occupied by a synchronization signal block (SSB) of the first cell and system information (SI) of the first cell. The terminal device sends a wake-up signal (WUS) to the first cell, where the wake-up signal is used to wake up the first cell to send the SSB and/or the SI. In this way, the terminal device can quickly access the cell, to reduce a delay of accessing the cell by the terminal device, and improve communication performance. The time domain resources occupied by the reference signal are fewer than the total time domain resources occupied by the SSB of the first cell and the SI of the first cell.

Abstract: Example cell access methods and apparatus are described. In one example method, a terminal device receives a first message in a cell of a first carrier. The first message includes remaining minimum system information (RMSI) of a cell of a second carrier and a first indication, and the first indication indicates information about a first bandwidth part (BWP). The terminal device accesses the cell of the second carrier based on the first BWP and the RMSI.

Abstract: Embodiments of this application provide example communication methods and example devices. One example method includes sending, by a first access network device, a system information block to a terminal device, where the system information block includes first information indicating that a cell served by the first access network device supports non-public network (NPN) onboarding, where the first information includes second information indicating a supported onboarding NPN, and the second information includes at least one of information about an identifier of the supported onboarding NPN or first indication information, where the first indication information indicates a support of onboarding. The first access network device can then receive a radio resource control (RRC) setup complete message from the terminal device, where the RRC setup complete message indicates that the terminal device requests NPN onboarding.

Abstract: Embodiments of this application disclose a paging collision processing method and a related apparatus. The method includes: When a terminal device detects that a paging occasion of the terminal device in a first camped cell collides with a paging occasion of the terminal device in a second camped cell, the terminal device may determine a first paging parameter, and may send first information including the first paging parameter to a first network device corresponding to the first camped cell. The first network device sends second information including a second paging parameter to the terminal device. The terminal device determines a second paging occasion of a first identity module card of the terminal device in the first camped cell based on the second paging parameter in the received second information. The terminal device monitors a paging message in the first camped cell on the second paging occasion. The second paging occasion does not overlap a third paging occasion of a second identity module card of the terminal device in the second camped cell in terms of time. According to embodiments of this application, a paging collision that occurs when the terminal device monitors the paging message can be avoided.

Abstract: A synchronization signal/broadcast signal block broadcast method and an apparatus are disclosed. The method includes: A first access network device RAN 1 determines to request a second access network device RAN 2 to perform resource allocation for a terminal; and the RAN 1 sends, to the RAN 2, a first message used to indicate the RAN 2 to broadcast a synchronization signal/physical broadcast channel block SSB. Accordingly, the RAN 2 starts to broadcast the SSB. The first message further includes a broadcast periodicity for the SSB. The broadcast periodicity is further sent by the RAN 1 to the terminal. The RAN 2 stops, based on a specific situation, broadcasting the SSB.

Abstract: This application discloses a communication method, a related device, and a computer storage medium. The method includes: receiving, by a core network node, a first message, where the first message includes orbit information of a satellite node; and determining, by the core network node, first area identity list information based on the orbit information, and sending the first area identity list information to a terminal, where the first area identity list information includes at least one first area identity, and the first area identity is used for access or mobility management of the terminal. This application helps the core network node perform access or mobility management on the terminal and track a location of the terminal. This implements non-terrestrial communication.

Abstract: The present disclosure relates to data transmission methods and apparatus to implement quality of service (QoS) flow-based data transmission in an architecture in which a central unit-control plane (CU-CP) and a central unit-user plane (CU-UP) are separated from each other. In one example method, when receiving data of a QoS flow, the CU-UP may send a QoS flow identity (ID) and a protocol data unit (PDU) session ID that are of the data of the QoS flow to the CU-CP, where a PDU session corresponding to the PDU session ID includes the data of the QoS flow.
