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 communication method is provided. In the method, if a first logical channel of a terminal device does not have an uplink resource for carrying a scheduling request (SR) and the terminal device is in a first SR state, remaining, by the terminal device, in the first SR state and/or a first buffer status report (BSR) state until data of the first logical channel and/or a BSR are/is sent, where the BSR is used to indicate buffer status information of a logical channel group including the first logical channel. When a logical channel of the terminal device does not have an uplink resource for carrying the scheduling request, a problem that the terminal device cannot obtain an uplink transmission resource can be resolved.
