Abstract: A user equipment (UE) or network device such as a Vehicle-to-Everything (V2X) node, or V2X device operates to configure sidelink signals with another vehicle or node with resources that can be used for ranging and sidelink communications within a Long Term Evolution (LTE) network or a New Radio (NR) network. The UE/device generate or process a broadcast communication of the sidelink signal via an adaptive antenna array or a directional antenna array and forming a directional radiation pattern from a beam sweeping operation based on geo-location information determined based on a sidelink signal. Depending on the geo-location information coordinates or the position of other vehicles or nodes can be derived to select or configure resources for a sidelink communication, including a Sidelink Ranging Reference Signal (SR-RS) and associated sidelink communication data.

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: A Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB is configurable to operate as a source gNB. The gNB is configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU comprises 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. When a handover of a User Equipment (UE) from the source gNB to a target gNB is performed, the gNB transfers, from the gNB-DU to the gNB-CU-UP, a downlink data delivery status (DDDS) message to indicate that the gNB-CU-UP is to stop transfer, to the gNB-DU, of downlink data intended for the UE.

Abstract: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.

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: 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: Some demonstrative embodiments include devices, systems and methods of providing offloadability information to a User Equipment (UE). For example, a core network (CN) may provide to the UE Packet Data Network (PDN) offloadability information corresponding to one or more PDN connections of the UE, the PDN offloadability information indicating which PDN connection of the one or more PDN connections is able to be offloaded to a Wireless Local Area Network (WLAN).

Abstract: Some demonstrative embodiments include devices, systems and methods of Access Network Discovery and Selection Function (ANDSF) for traffic offloading. For example, an ANDSF Management Object (MO) may include one or more ANDSF policies, at least one ANDSF policy including ANDSF selection criteria to offload traffic between a cellular network and a Wireless Local Area Network (WLAN); and a preference indicator to indicate a preference between the ANDSF selection criteria and Radio Access Network (RAN) selection criteria from the cellular network.

Abstract: Apparatuses, systems, and methods for a framework for user consent delivery and utilization in cellular communication systems. An access and mobility management function (AMF) of a network may obtain, from a user data management (UDM), user consent information via a user consent parameter included in a structured data type. The AMF may provide, to a base station of the network, the user consent information via a user consent information element. The user consent information element may be associated with at least one data type and the at least one data type may include radio link failure (RLF) information sharing consent and/or user location information sharing consent. The user consent information element may be included in any of an initial context setup request message, a user equipment (UE) context modification request message, and/or a handover request message.
