1. A method of a user equipment (UE), comprising:
initiating, with a wireless network, a small data transmission (SDT) procedure; wherein the SDT procedure is performed while the UE is in an inactive state;
performing, during an SDT measurement period of the SDT procedure, measurements of a plurality of cells of the wireless network;
determining, during the SDT measurement period, respective qualities of the plurality of cells of the wireless network based on the measurements of the plurality of cells;
detecting, during the SDT measurement period, a measurement event according to one or more of the respective qualities of the plurality of cells; and
sending, in response to the detecting of the measurement event, one of an RRCResumeRequest message and an RRCReestablishmentRequest message.
