1. A method for a user equipment device (UE), comprising:
receiving, from a base station, an indication enabling a small data transmission (SDT) procedure along with an indication of a radio access network (RAN) notification area (RNA) timer configuration, wherein the RNA is stopped upon initiation of the SDT procedure and started upon termination of the SDT procedure;
transitioning to a radio resource control (RRC) inactive state;
receiving, during the SDT procedure, an updated RNA timer configuration in at least one of an SDT termination indication or an SDT subsequent transmission indication; and
initiating an RNA timer based on the updated RNA timer configuration; and
wherein the SDT procedure is terminated after a subsequent transmission period of the SDT procedure.
