Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configurable to operate as a source gNB (S-gNB). The S-gNB may transfer, from a control plane (CU-CP) of the S-gNB to a CU-CP of a target gNB (T-gNB), an XnAP handover request message that indicates an Xn handover of a User Equipment (UE) from the S-gNB to the T-gNB. The S-gNB may initiate data forwarding, from a user plane (CU-UP) of the S-gNB to a CU-UP of the T-gNB, of downlink data packets. The data forwarding may be terminated based on reception of end marker packets from a user plane function (UPF) entity. The CU-UP of the S-gNB may transfer end marker packets to the CU-UP of the S-gNB to indicate termination of the data forwarding.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.

Abstract: Some demonstrative embodiments include devices, systems and methods of offloading traffic of a Secondary Cell Group (SCG). For example, some embodiments may include identifying a SCG bearer that is offloadable to the Internet via a Network Address Translation (NAT) gateway, based on offloading information received from a Master Evolved Node B (eNB) (MeNB); and offloading uplink Internet Protocol (IP) packets of the SCG bearer to the Internet via the NAT gateway, if the SCG bearer is indicated to be offloadable.

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-RNTI) 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: A UE may coordinate the use of a low Power Wake-Up Radio (LR) and a main radio (MR) to determine a Radio Resource Management (RRM) measurement. The UE may enter a deep sleep state by turning off a MR and turning on a LR. The UE may measure the serving cell quality when in the deep sleep state, and enter a normal state by turning on the MR, when the serving cell quality is less than a threshold. The UE may perform a neighbor cell measurement, when in the normal state when a serving cell measurement meets a criteria.

Abstract: Apparatuses, systems, methods, and computer-readable media associated with F1 interface arrangement configuration within a network that implements virtualized NodeBs are disclosed herein. In embodiments, one or more non-transitory computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by one or more processors, cause a centralized unit (CU) of an access node to generate a CU configuration update message, the CU configuration update message to include an indication of a transport network layer (TNL) address of the CU for which a TNL association between the CU and a distributed unit (DU) of the access node is to be added or removed, and cause the CU configuration update message to be transmitted to the DU. Other embodiments may be described and/or claimed.

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 NRnode 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: Techniques are directed toward network identification collision detection. An example method includes selecting a first subscriber identity module (SIM) associated with a public land mobile network identifier (PLMN ID) and a network identifier (NID) of a private network. The method can further include generating a first non-access stratum (NAS) registration request to establish a connection with the private network using the first SIM. The method can further include processing a NAS registration request reject message received from the private network. The method can further include selecting a second SIM associated with the PLMN ID and the NID. The method can further include generating a second NAS registration request to establish a connection with the private network using the second SIM. The method can further include processing a NAS registration request success message received from the private network. The method can further include logging NID collision information.
