摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
