Abstract: An approach is described for a method for a radio access node (RAN) node in a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes generating a request for location information of a user equipment (UE). The method further includes transmitting the request to an access and mobility function (AMF). The method further includes receiving a response from the AMF, wherein the response comprises the location information of the UE.

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 a second 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: A computer system that establishes a first registration and a second registration in a common wireless communication system is described. During operation, the computer system performs a first registration of the user equipment over a first access, where, after the first registration, the user equipment is connected via the first access with a first access and mobility management function (AMF). Then, the computer system performs a second registration of the user equipment over a second access, where the second access is different from the first access and, after the second registration, the user equipment is connected via the second access with a second AMF. Moreover, when performing the second registration, the computer system: transfers a context of the user equipment from the first AMF to the second AMF; and/or relocates a network interface in a control plane from the first AMF to the second AMF.

Abstract: Devices, methods, user equipment (UE), base stations, storage media, and other embodiments are provided for managing associations in a communication network. In one example embodiment, a Next Generation (NG) core network device is configured for an Access and Mobility Management Function (AMF) with an NG-Radio Access Network (NG-RAN) node. The network device may be configured to access a plurality of Transport Network Link (TNL) associations and generate an AMF configuration update using the TNL associations, the AMF configuration update comprising AMF transport layer address information for the plurality of TNL associations. The network device may then initiate transmission of the AMF configuration update comprising the AMF transport layer address information to the NG-RAN node. Additional embodiments may involve binding updates or setup response messaging for managing associations, along with additional operations.

Abstract: A user equipment (UE), a baseband processor or other network device can operate in a new radio (NR) unlicensed network can operate to communicate in a UE to UE (U2U) relay path through a first relay UE with another UE as a source or destination UE according to a direct communication request initiating from the source UE. The UE, as a source UE, can also perform the U2U relay reselection based on a measurement report received from a destination UE.

Abstract: A master node (MN) that determines a manner of a protocol data unit (PDU) session to be served, wherein the manner of the PDU session includes a split PDU session between the MN and a secondary node (SN) or a whole PDU session served by the MN, generates a request message to be transmitted to the SN to setup PDU session resources on the SN based on the manner of the PDU session is to be served and indicates, to the SN, the manner of the PDU session to be served. A SN that receives, from a MN, a request message to setup PDU session resources, determines a manner of the PDU session to be served, and sets up the PDU session resources on the SN, based on at least the manner of the PDU session to be served.

Abstract: Techniques are disclosed for the harmonization of a spectrum access tier and a core network architecture. One example includes a method implemented for the harmonization of a spectrum access tier and a core network architecture. An access and mobility management function (AMF) of a first network can receive a first request message, including a spectrum inquiry request from a base station to an automated frequency coordinator of the first network. The automated frequency coordinator can use an AMF interface and an automated frequency coordinator interface to determine a spectrum inquiry response. The spectrum inquiry response can describe an available frequency band of a spectrum access tier of a second network for the base station. The AMF can transmit the spectrum inquiry response to the base station.

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 include 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: 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.
