Abstract: An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors to process a radio resource control (RRC) resume request (RRCResumeRequest) from a user equipment (UE) in an inactive state (RRC INACTIVE), and to send a UE context request (Retrieve UE Context Request) to a last serving gNB, wherein the UE context request includes a physical cell identifier (PCI) and cell radio network temporary identifier (C-RNT1) of the gNB. The apparatus can include a memory to store the RRC resume request at the gNB and the UE context request at the last serving gNB.

Abstract: Devices, methods, communication nodes, base stations, storage media, and other embodiments are provided for managing associations in a communication network. In one example embodiment, a New Radio (NR) node is configured for NR user-plane protocol communications between a master node (MN) and a secondary node (SN). The NR node is configured to generate a downlink (DL) user data message with downlink user data, initiate transmission of the DL user data message to a second node, and process a DL data delivery status message from the second node in response to the DL user data message. In various embodiments, polling and SCG split-bearer configurations are supported by such messaging. In some embodiments, packet data convergence protocol (PDCP) serial numbers are communicated for transmission and retransmission management. In some embodiments, DL configurations initiated by an SN are enabled, as well as UL configurations initiated by either an MN or an SN.

Abstract: An apparatus of a next generation Node B (gNB) Distributed Unit (DU) comprises one or more baseband processors to transmit one or more retransmitted Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) received from a gNB Central Unit (CU) to a user equipment (UE), and to feed back not only a latest, in-sequence New Radio User-plane (NR-U) Sequence Number (SN) to the CU for Release 15, but also a highest, in-sequence successfully delivered/transmitted PDCP SN, optionally, with a NR-U SN up to which the reported PDCP SN should be applied, which can provide an exact range of successfully delivered/transmitted status for retransmitted packets even in case of DU's re-ordering based on PDCP SN before transmitting to the UE. The apparatus can include a memory to store the reported PDCP SN and NR-U SN.

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-OU). 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.

Abstract: Techniques to configure a user equipment (UE) for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding a measurement report for transmission to the SBS. The measurement report is triggered based on a measurement event configured by the SBS. Radio resource control (RRC) signaling from the SBS is decoded, the RRC signaling including a handover command in response to the measurement report. The handover command includes an indication for multi-connectivity support by the SBS and the TBS during the handover. A first protocol stack associated with the SBS and a second protocol stack associated with the TBS are configured at the UE. A packet data convergence protocol (PDCP) protocol data unit (PDU) received at the UE during the handover is processed using the first protocol stack or the second protocol stack.

Abstract: Apparatuses, systems, and methods for a network node to inter-connect with a first secondary node (SN) within a core network. The network node may be a master node and may serve a UE. The first SN may be a source SN. The network node may initiate a change from the first SN to a second SN, which may be a target SN. The network mode may determine data forwarding from the first SN to the second SN and may request, from the first SN, data forwarding intentions prior to initiating the change from the first SN to the second SN. The network node may send, to the first SN, data forwarding instructions (e.g., based, at least in part, on the data forwarding intentions of the first SN) and the data forwarding instructions may include a requirement for the first SN to follow the data forwarding instructions.

Abstract: This disclosure describes methods, systems, and devices for uplink data integrity protection in a communication system including a radio access network (RAN) serving a user equipment (UE) operating in an Early Data Transmission (EDT) configuration. In one example, a method involves generating a hash marker based on a packet data convergence protocol (PDCP) control protocol data unit (PDU) or service data unit (SDU). The method also involves transmitting a message including the hash marker to the RAN.
