1. A method for non-small data transmission (SDT) dedicated radio bearer (DRB) handling for a user equipment device (UE), comprising:
determining, while the UE is operating in a radio resource control (RRC) inactive state and during an initial transmission period of an SDT procedure, that non-SDT data is available for transmission on a non-SDT DRB;
refraining from sending an initial access message based, at least in part, on the determining that the non-SDT data is available;
receiving an indication to enter a subsequent transmission period of the SDT procedure; and
transmitting, to a base station and based on the indication, non-SDT data arrival information during the subsequent transmission period of the SDT procedure.
