Enhancements towards 5G New Radio (NR) V2X are under study in Release 16 in order to support advanced vehicular use cases with stricter latency and reliability demands, and different traffic patterns (e.g., aperiodic messages, unicast delivery).

Dec 22, 2021 · Efforts to improve the Packet Delivery Ratio (PDR) performance of these two messages are needed for reliable vehicular communication. This letter first proposes a C-V2X Sensing Sharing (SS) scheme to improve the DENM and CAM PDR performance.

Nov 5, 2020 · V2X safety messages can include a Cooperative Awareness Messages (CAM), a Decentralised Environmental NotificationMessages (DENM) or a Basic Safety Message (BSM). The CAM and DENM can be used in European (EU) standards and the BSM in United States (US) standards. CAM messages are broadcasted quasi-continuously (at

V2X systems are supported by wireless networks for exchange of information between vehicles (V2V) and road side infrastructure (V2I). The V2X system enables a wide range of beneficial use cases.

The type of data packets used to communicate in the C-V2X includes periodic and aperiodic messages and they use the same resource pool. In this work, we proposed a novel method that can support dividing the whole resource pool for the periodic and aperiodic messages.

Jan 20, 2023 · The application of V2X (Vehicle-to-Everything) communication technologies to the next generation of Advanced Driver Assistance Systems (ADAS) is essential to the extension of the operational design domain (ODD) of the systems to provide safe, secure, and efficient automated driving solutions.

Feb 1, 2024 · In this paper, we present a novel Edge computing infrastructure for safer level crossings, leveraging Cooperative Awareness Message (CAM) and Decentralized Environmental Notification Message (DENM) exchanges to identify hazardous situations.

This paper proposes an enhanced Cellular vehicles-to-everything (C-V2X) mode-3 networking with i) scalable overlapped eNodeBs (eNBs) with orthogonal radio frequency (RF) resource management with minimized RF interference, ii) smart handover across overlapped eNBs to minimize the signaling overhead, and iii) prompt wide-area propagation of DENM ...

Mar 4, 2025 · The DENM is a standardized V2X message format used to share event-based safety information. In this study, the YOLOv5 pedestrian detection results were encoded into DENM messages using ASN.1 schemas, verifying compliance with ETSI ITS standards.

Efforts to improve the Packet Delivery Ratio (PDR) performance of these two messages are needed for reliable vehicular communication. This letter first proposes a C-V2X Sensing Sharing (SS) scheme to improve the DENM and CAM PDR performance.
