receiving control signaling activating the configured grant-small data transmission functionality of the UE, the control signaling comprising the configuration information.

8. The method of claim 1 , further comprising:

receiving, after performing the action, second configuration information, the second configuration information indicating a second mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE to second respective short message bit positions.

9. A user equipment (UE) for wireless communication, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

receive configuration information, the configuration information indicating a mapping of one or more actions pertaining to configured grant-small data transmission functionality of the UE to respective short message bit positions;

receive, while the UE is in an inactive state, a notification in a form of downlink control information with a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE;

identify, using the mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE to the respective short message bit positions, the action from at least one short message bit position of the one or more bits; and

perform the action according to the instruction as pertaining to the configured grant-small data transmission functionality while the UE is in the inactive state.

10. The UE of claim 9 , wherein the downlink control information includes cyclical redundancy check information scrambled by a paging radio network temporary identifier.

11. The UE of claim 9 , wherein to perform the action, the at least one processor is configured to cause the UE to:

determine that a small data transmission is to be transmitted by the UE; and

implement a random access channel procedure for the small data transmission to determine that the configured grant-small data transmission functionality is at least temporarily unavailable.

12. The UE of claim 9 , wherein to receive the configuration information, the at least one processor is configured to cause the UE to:

receive control signaling activating the configured grant-small data transmission functionality of the UE, the control signaling comprising the configuration information.

13. A base station for wireless communication, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the base station to:

generate configuration information, the configuration information indicating a mapping one or more actions pertaining to configured grant-small data transmission functionality of a user equipment (UE) to respective short message bit positions;

transmit the configuration information for receipt by the UE;

generate a notification in a form of downlink control information with a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of the UE while the UE is in an inactive state; and

transmit the notification for receipt by the UE while the UE is in the inactive state.

14. The base station of claim 13 , wherein the downlink control information includes cyclical redundancy check information scrambled by a paging radio network temporary identifier.

15. The base station of claim 13 , wherein the downlink control information includes one or more of a device identifier for the UE or a group identifier for a group that includes the UE.

16. The base station of claim 13 , wherein the action comprises one or more of to deactivate or deconfigure a configured grant configuration of the UE.

17. The base station of claim 13 , wherein the action includes one or more of to stop a timing advance timer, expire the timing advance timer, or invalidate the timing advance timer.

18. The base station of claim 13 , wherein the action comprises to disable the configured grant-small data transmission functionality of the UE.

19. The base station of claim 13 , wherein the base station includes a component of a radio access network, the at least one processor configured to cause the base station to generate the notification independent of an instruction from a core network.

20. A processor for wireless communication, comprising:

at least one controller coupled with at least one memory and configured to cause the processor to:

receive configuration information, the configuration information indicating a mapping of one or more actions pertaining to configured grant-small data transmission functionality of the processor to respective short message bit positions;

receive a notification in a form of downlink control information a short message field including one or more bits, the notification including an instruction indicating to perform an action of the one or more actions pertaining to the configured grant-small data transmission functionality of a device while the device is in an inactive state;

identify, using the mapping of the one or more actions pertaining to the configured grant-small data transmission functionality of the processor to the respective short message bit positions, the action from at least one short message bit position of the one or more bits; and
