    Abstract: Systems and methods of modifying the bearer context of a DRB of an E1 interface for a gNB are described. To modify the bearer context associated with a DRB for a particular UE, the gNB-CU-UP transmits a Bearer Context Modification Required message through the E1 interface and receives in response a Bearer Context Modification Confirm message that confirms the modification of the bearer context. The Bearer Context Modification Required message and Bearer Context Modification Confirm message both include the new GTP TEID and TNL address to be used after modification of the bearer context, a gNB-CU-CP UE E1AP ID that uniquely identifies a UE association over the E1 interface within the gNB-CU-CP, a gNB-CU-UP UE E1AP ID that uniquely identifies a UE association over the E1 interface within the gNB-CU-UP, and a DRB ID IE that uniquely identifies the DRB.

    Abstract: There is are provided methods and apparatus relating to layer 2 relaying and mobility using a sidelink interface, including a remote user equipment (UE) for use in a wireless communication network, the UE comprising: a device to network (D2N) entity, a device to device (D2D) entity, and control logic to: receive a service data unit derived from an IP packet direct the service data unit to the D2N entity for communication with an eNB using a Uu interface in a first mode of operation, and direct the service data unit to the D2D entity for communication with the eNB via a first relay UE using a sidelink interface in a second, relay, mode of operation.

    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: 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: Packet protection is described. Data of a group of packets is concatenated with a security key and a sequence number of the packet. A hash mark of the concatenated data is calculated and sent with data or control information in a packet. If each packet has reserved bits, at least some of the packets each has data, a least a portion of the hash mark, and a header having: a first bit that indicates if the hash mark is present, and a second bit that indicates if the packet is used to determine the hash mark. Otherwise, a separate control packet is sent that contains the hash mark, a first sequence number of the group of packets, and a PDU type indicating that the control packet is an integrity protection packet for the group of PDCP packets.

    Abstract: Systems and methods of setting up an E1 interface for a gNB are described. A transmitting entity of the gNB-CU-CP and gNB-CU-UP initiates the first TNL association between the gNB-CU-CP and gNB-CU-UP, and is also limited to initiating the E1 Setup procedure. The transmitting entity sends an E1 SETUP REQUEST message to set up the E1 interface. Afterwards, a message is received from the receiving entity. The transmitting entity determines that the setup of the E1 interface is successful if the message contains IEs of an E1 SETUP RESPONSE message. The types of IEs include a message type IE and a name of the transmitting entity.
