Small Data Transmission

원문 (중국어)

A wireless device receives, from a first base station, a RRC release message comprising a suspend configuration, wherein the suspend configuration comprises a configuration of a SDT procedure, and the configuration indicates a radio bearer configured for the SDT procedure. The wireless device suspends, based on the suspend configuration, one or more radio bearers comprising the radio bearer configured for the SDT procedure. Based on initiating the SDT procedure the wireless device resumes the radio bearer configured for the SDT procedure and transmits, to a second base station, a radio resource control (RRC) resume request message. The wireless device communicates with the second base station and during the SDT procedure, data associated with the SDT procedure, receives, from the second base station, a second RRC release message comprising a resume indication after completion of the SDT procedure, and initiates, based on the resume indication, an RRC resume procedure.
