Abstract: A communications method and apparatus are provided. The method includes: A first access network device sends a first message to a core network device, where the first message is used to indicate to suspend one or both of a first PDU session and a second PDU session. The first PDU session and the second PDU session are PDU sessions that are established as requested by a same terminal, and are used to transmit a duplicated data packet. According to the method, when a condition for implementing reliable transmission is not met, the core network device can be indicated to suspend the PDU session. In this way, a PDU session does not need to be re-established, and signaling overheads for establishing the PDU session are saved.

Abstract: The present disclosure relates to wireless communication methods, terminal devices, and network devices. In one example method, a network device sends timing advance timer (TAT) configuration information to a terminal device, where the TAT configuration information is used by the terminal device to configure duration of a TAT. The terminal device receives the TAT configuration information sent by the network device. The terminal device configures the TAT based on the TAT configuration information, and asynchronously sends uplink data to the network de vice based on a running status of the TAT. The network device receives the uplink data sent by the terminal device based on the TAT configuration information.

Abstract: Example data processing methods and apparatuses are disclosed. In one example data processing method, a first terminal obtains packet delay budget adjustment information, where the packet delay budget adjustment information is used to indicate an adjusted packet delay budget, a packet delay budget adjustment amount, or a packet delay budget adjustment range. The first terminal adjusts a size of a jitter buffer based on the packet delay budget adjustment information, and then buffers data based on the adjusted jitter buffer.
