The first indication information is used to indicate the first terminal device to wake up when the first wakeup indication is not detected.

Terminal device wakeup method and apparatus, network device, and terminal device

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.

The method effectively avoids PDCCH-only of the terminal device in the first cell.

Conditional physical downlink control channel (PDCCH) monitoring

A communication method includes that, when a terminal device receives indication information used by a network device to indicate the terminal device to work on a non-dormant bandwidth part (BWP) in a secondary cell, the terminal device can determine a specific BWP on which the terminal device is to work, and perform a corresponding operation. A network device generates indication information, and sends the indication information to a terminal device, where the indication information is used to indicate the terminal device to work on a non-dormant BWP in a first secondary cell. Then, the terminal device enables, according to the indication information, the terminal device to work on a first BWP, where the first BWP is the non-dormant BWP in the first secondary cell.

The technology of this application relates to a communication method and apparatus. The method includes a terminal device sending first indication information to a network device, where the first indication information indicates that a switching delay between a first bandwidth part BWP and a second BWP is first duration, where the first BWP and the second BWP are uplink BWPs or downlink BWPs used by the terminal device to send and receive data. The terminal device can indicate to the network device a specific switching delay between two BWPs in a serving cell, so that a BWP switching delay determining method is more flexible and a result is more accurate.

A message transmission method is provided. User equipment may receive a power saving message from a network device, where the power saving message carries indication information of a short message, and the short message includes at least one of the following: a public warning system notification or system information modification information. Then, the user equipment obtains the short message from the power saving message. In this way, when the user equipment is in a connected state, the user equipment may obtain the short message by using the power saving message, for example, a PoSS, instead of by monitoring a paging PDCCH; and when the UE is in a sleep state, the UE is not woken up to monitor the paging PDCCH. This reduces power consumption of the user equipment in the connected state.
