Oct 18, 2021 · Abstract: The Third Generation Partnership Project (3GPP) has recently published a new set of specifications to enable advanced driving applications in fifth generation (5G) vehicle-to-everything (V2X) scenarios, with particular effort dedicated to the sidelink resource allocation in the autonomous mode, named Mode 2. In this paper, we conduct ...

• Resource reservation for NR V2X Mode 2 under periodic traffic mostly reuses the LTE C-V2X sidelink Mode 4 long-term sensing-based semi-persistent scheduling. • In addition, NR V2X Mode 2 also supports a random resource selection.

Mar 11, 2025 · By the 3GPP NR V2X Mode 2, vehicles first specify the cycles for radio resources (or say subchannels) they require and then reserve subchannels by themselves. While traveling on the road, vehicles may generate periodic and non …

Jul 29, 2024 · NR Sidelink Mode 2 in Unlicensed Bands: Throughput Model and Validation Abstract: Sidelink is a 3GPP-standardized technology that enables direct UE-to-UE communication. Initially designed for licensed 4G spectrum (Release 15), it expanded to 5G NR (Release 16, 17).

In this paper, we provide a complete history of sidelink technology in 3GPP followed by a detailed overview of NR V2X technology, with special emphasis on Mode 2 for out of coverage operation and autonomous resource selection.

In LTE-V2X with Mode 3, two scheduling options are available: dynamic scheduling, where the resources are requested individually for each transmitted data block, and semi-persistent scheduling, where the eNodeB reserves the resources for transmission of multiple data blocks.

Aug 1, 2023 · Standardized by the Third Generation Partnership Project (3GPP) in Release 16, NR-V2X features a distributed resource allocation mode, known as Mode 2, that allows vehicles to autonomously select their transmission resources employing a Semi-Persistent Scheduling (SPS) or a Dynamic Scheduling (DS) scheme.
