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 small data transmission (SDT) procedure indicating a radio bearer configured for the SDT procedure. The 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, and transmits to the second base station and during the SDT procedure, a user equipment (UE) assistance information message comprising a non-SDT indication, wherein the non-SDT indication indicates availability of data mapped to a radio bearer which is not configured for the SDT procedure, and a resume cause associated with the data. The wireless device receives, from the second base station and after transmitting the UE assistance information message, an RRC response message.
