Abstract: This application provides a communication method and apparatus. The method may be applied to a small data transmission procedure. The method includes: A terminal device receives first indication information from a network device, where the first indication information indicates timing advance information. The terminal device performs the following operations based on a running state of at least one of a first time alignment timer and a second time alignment timer: applying the first indication information or ignoring the first indication information.

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.
