Abstract: Described is a network device (203) configured to operate as a first node in a communications network (200) for a user device (201) initiating a small data transmission communication session through a target node (202) in the communications network (200), the network device (203) being configured to, upon receiving a request from the target node (202), send a message to the target node (202), the message comprising an indication of small data transmission configuration information (401, 506) for the user device (201). A corresponding network device (202) configured to operate as a target node is also described.

Abstract: Embodiments of this application disclose a data transmission method and an apparatus. The method includes: When a terminal device is in a radio resource control RRC inactive state, the terminal device selects a first synchronization signal block SSB at first time, and sends first small data transmission SDT data to a network device by using a first configured grant CG resource corresponding to the first SSB; and when signal quality of a plurality of SSBs at second time is greater than a first threshold, the terminal device preferentially selects the first SSB from the plurality of SSBs at the second time, and sends second SDT data to the network device by using a second CG resource corresponding to the first SSB.

Abstract: A random access method and apparatus are provided. The method includes: The terminal device receives system information that indicates a first random access configuration of N first features of a network device, one first feature is one feature or one feature combination, the first random access configuration includes M first configurations and N second configurations, there is a correspondence between the M first configurations and the N second configurations, and M and N are positive integers. The terminal device initiates random access based on the first random access configuration. A random access configuration is for the N first features, and the first configuration is a shared configuration. The shared configuration may be a parameter shared by a plurality of first features. The second configuration is a dedicated configuration and is a configuration applicable to the one first feature.
