Abstract: Technology is disclosed for a vehicle-capable user equipment (vUE) operable for sensing-based distributed scheduling 5 of event-based mission critical (MC) vehicle-to everything (V2X) traffic. The vUE can sense sidelink control information (SCI) for semi persistent scheduling (SPS) resource selection from one or more SCI messages received in one or more physical sidelink control channels (PSCCHs) from one or more neighboring vUEs. The vUE can identify: a number of MC resources to transmit event10 based MC data with a selected number of repetitions within a latency budget, wherein the MC resources include one or more of MC-SCI or MC data with the selected number of repetitions; and a number of available resources to transmit event-based MC data within the latency budget. The vUE can select revocable resources from one or more scheduled low-priority resources based on the sensed SCI for SPS resource selection.

Abstract: Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.

Abstract: An SDN architecture, for a cellular communications system, is described herein that includes a Quality of Service (QoS) provisioning framework to provision and manage traffic flows in the cellular communications system. The described architecture separates the control plane and the user plane for the transport of the user plane traffic. Network entities in the SDN architecture, such as a network controller, can detect and react to changes in network state (e.g., load conditions) to route or reroute traffic flows in the network. QoS and routing parameters may be determined for the network traffic on a per-flow basis, even when multiple flows are associated with a single service request.

Abstract: Described is a Logical Network Controller (LNC) operable to communicate with a User Equipment (UE) on a wireless network. The LNC may be operable to process connection request transmissions from the UE requesting a connection with an application service, such as a Mission-Critical Internet-of-Things (MC-IoT) service, to determine a Connection-specific Application Server Instance (CASI) for the application service, and to generate connection response transmissions for the UE carrying a connection-specific source IP address corresponding to the UE and a connection-specific destination IP address corresponding to the CASI. The UE may be operable to generate connection request transmissions for the LNC requesting a connection with an application service, to process connection response transmissions from the LNC carrying a connection-specific destination IP address corresponding to a CASI for the application service, and to generate connection-specific transmissions for the CASI, the connection-specific transmissions carrying the connection-specific destination IP address.
