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: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.

Abstract: An Ethernet header compression method and apparatus and an Ethernet header decompression method and apparatus. After receiving an Ethernet frame including a first to-be-compressed field, a compression end compresses an Ethernet header of the Ethernet frame based on a first correspondence including first compression information and a value of the first to-be-compressed field and the first compression information. Correspondingly, a decompression end decompresses an Ethernet header of a compressed Ethernet frame based on the first correspondence when receiving the compressed Ethernet frame. In the embodiments of this application, because the Ethernet header of the Ethernet frame is compressed, communication resources is saved.

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.
