Abstract: A centralized node collects and stores radio access network (RAN) user plane congestion information (RCI) that is reported from the RAN to a core network. The centralized node provides a congestion information collection function (CICF) and includes one or more interface to communicate with a mobility management entity (MME) and/or a serving general packet radio service (GPRS) support node (SGSN). The MME and/or SGSN allows the centralized node to determine user equipments (UEs) and associated access point name (APNs) impacted by RAN congestion. The centralized node reports the RCI to a policy and charging rules function (PCRF) associated with the APNs for congestion mitigation.

Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. The UE may be configurable to operate as an initiating UE for a vehicle-to-everything (V2X) application that includes PCS communication between the initiating UE and a receiving UE. The initiating UE may receive, from a base station, control signaling that indicates a default PCS radio access technology (RAT) for the V2X service. The default PCS RAT may be either a Long Term Evolution (LTE) PCS RAT or a New Radio (NR) PCS RAT. Based on the default PCS RAT and/or PCS RATs supported by the initiating UE, the initiating UE may select either the LTE PCS RAT or the NR PCS RAT. The selected PCS RAT may be proposed, in a negotiation with the receiving UE, for the V2X service.
