    Abstract: The present disclosure is generally related to wireless and cellular communication, communication system implementations, and in particular, to support for mobile terminated small data transmission (MT-SDT) in 5G systems (5GS). A UE initiates a radio resource control (RRC) resume procedure with a resume cause value of “mt-SDT” in an RRC resume request when a mobile terminated small data transmission (MT-SDT) indication for the UE is included in a received paging message and a set of conditions for initiating MT-SDT have been fulfilled. The UE initiates the RRC resume procedure with a resume cause value of “mt-Access” in the RRC resume request message when the set of conditions for initiating MT-SDT have not been fulfilled. Other embodiments may be described and/or claimed.

    Abstract: Embodiments of a Next Generation Node B (gNB) are described herein. The gNB may be configured with logical nodes, including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may comprise a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. The gNB may initiate an E1 interface setup procedure, a bearer context setup procedure, and a UE context setup procedure to establish a UE context that includes a signaling radio bearer (SRB) and a data radio bearer (DRB) configuration. The UE context setup request message may be configured to include quality-of-service parameters for the DRB configuration.
