Embodiments of this application provide a data transmission method and an apparatus. When more than two radio link control RLC entities are configured for one radio bearer RB, a secondary network device receives indication information from a master network device. The secondary network device may determine, based on the indication information, a master RLC entity associated with the radio bearer, to indicate, to a terminal device, RLC entities that need to be activated and deactivated.

Communication method and apparatus

A terminal device generates a report result including at least one of a logged minimization of drive tests report, an RLF report, and an RACH report. The logged minimization of drive tests report includes an identifier of a candidate access cell, information indicating whether the candidate access cell supports a network slice service initiated by the terminal device, location information of the terminal device where the terminal device receives a system message of the candidate access cell, and a network slice identifier of the network slice service initiated by the terminal device. The RLF report includes an identifier of a cell in which a radio link failure occurs after the terminal device accesses the cell and the network slice identifier corresponding to the network slice service in which the radio link failure occurs on the terminal device. The RACH report includes an identifier of a cell accessed by the terminal device and the network slice identifier. The terminal device sends the report result to a radio access network device to which a serving cell belongs.

Data transmission method and apparatus

Embodiments of the present invention disclose a communication method, an apparatus, and a computer-readable storage medium. The method includes: receiving a first data packet; and sending the first data packet and first indication information to an access network device, where the first indication information indicates that the first data packet is an uplink data packet or a downlink data packet, and the first indication information is used by the access network device to determine an access network AN packet delay budget PDB of a first quality of service QoS flow corresponding to the first data packet.

Communication method, apparatus, and computer-readable storage medium

Embodiments of this application relate to the field of communication technologies, and provide a timing method for dealing with a link exception and an apparatus. A specific solution is as follows: receiving a first synchronization packet from a first terminal device; receiving a second synchronization packet from a second terminal device or a server; and if the first synchronization packet and the second synchronization packet belong to a same TSN domain, determining a to-be-forwarded synchronization packet in the first synchronization packet and the second synchronization packet. In this way, if the to-be-forwarded packet is the first synchronization packet, the first synchronization packet is forwarded, and the second synchronization packet is filtered. Embodiments of this application are used to improve timing precision in a timing process of the TSN device for the 5GS.
