Abstract: A communication method includes receiving, by a terminal device, first clock source information. The first clock source information corresponds to clock source information of a wireless communication system. The first clock source information indicates that a fifth generation (5G) system clock is useable as a clock source. The method further includes sending, by the terminal device, the first clock source information to an adjacent device.

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 wireless communication method and apparatus for improving communication failure recovery efficiency. The method is applied to a terminal or a chip used in a terminal, and includes: upon detecting that downlink communication of the first serving cell fails, determining that downlink communication of the second serving cell is normal; sending a communication failure recovery request on an uplink channel of the second serving cell, where the communication failure recovery request is used to request to recover from a downlink communication failure of the first serving cell; and detecting a communication failure recovery response on a downlink channel of the second serving cell, where the communication failure recovery response is used to indicate a downlink communication resource of the first serving cell.

Abstract: This application provides a reference signal transmission method, a terminal device, and an access network device. By receiving first indication information from the access network device, the terminal device can determine, based on the first indication information, whether N1 resource blocks that are in a rate matching pattern group and that have an intersection with a time-frequency resource for transmitting a downlink data channel can be used to transmit the downlink data channel, and further determine a position of a reference signal of downlink data channel, to implement reference signal transmission.

Abstract: Embodiments of the present invention provide a communication method and apparatus, and a computer-readable storage medium, to resolve a prior-art problem that data sending or data receiving of a terminal device is delayed. The method includes: if no monitoring occasion of a wake-up signal exists in a first time window, or a first time window includes no monitoring occasion of a wake-up signal in at least one search space set configured for a terminal device, monitoring a physical downlink control channel within an on duration time period of a discontinuous reception DRX state, where the first time window is a time window for monitoring the wake-up signal, the wake-up signal indicates the terminal device to monitor the physical downlink control channel within the on duration time period, and the first time window is prior to the on duration time period.

Abstract: A session management network element determines whether a first communication apparatus and a second communication apparatus have a redundancy functionality, receives a session establishment request message from a first terminal device, to request to establish a first session between the first terminal device and a data network. When both the first communication apparatus and the second communication apparatus have the redundancy functionality, and the first session is a redundant session, selects a first user plane function network element to establish the first session, where the second user plane function network element is configured to establish a second session, the first session is a redundant session of the second session, and the first session and the second session are for communication between the first communication apparatus and the second communication apparatus.

Abstract: A method for improving service reliability includes deciding, by a session function entity in a network, to initiate establishment of at least two transmission paths between a terminal and the user plane function entity, and instructing the terminal or the user plane function entity to transmit same data on the at least two paths. The user plane function allocates, based on a notification of the session function entity, user plane resources to the at least two transmission paths, and transmits the same data with the terminal on the at least two transmission paths. A core network initiates the establishment of the at least two transmission paths to the terminal. Two access devices may independently establish the at least two transmission paths.
