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: A data transmission method and apparatus are provided. One example method involves establishing two tunnels between an access network device and a user plane function network element, where the two tunnels may be tunnels used for downlink data transmission or tunnels used for uplink data transmission. When communicating with the user plane function network element, the access network device may transmit two data packets. In this way, when one data packet is lost, the receive end may further receive the other data packet.

Abstract: Embodiments of this application relate to a wake-up signal WUS detection method and apparatus, used 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: The present disclosure relates to terminal device wakeup methods and apparatus, network devices, and terminal devices. One example method includes receiving, by a first terminal device, configuration information of a first wakeup indication from a network device, where the first wakeup indication is used to indicate whether the first terminal device is to wake up, detecting, by the first terminal device, the first wakeup indication based on the configuration information, and in response to that the first wakeup indication is not detected, waking up, by the first terminal device, when the configuration information comprises first indication information. The first indication information is used to indicate the first terminal device to wake up when the first wakeup indication is not detected.
