“…Admission control and service processes are modeled individually for every session, where we assume that uplink and downlink traffic flows share the same set of radio resources. In the case where the network does not currently have sufficient resources available in the pool reserved for vehicular communications, the session is assumed to e.g., be offloaded onto another radio access technology 1 . While the emerging 5Ggrade networks are expected to be packet-switched, the endto-end quality of service (QoS) is envisioned to still be maintained at the session level [37], [38].…”

“…The envisioned emergence of connected autonomous vehicles is one of the major disruptions introduced on the way from 4G and 4G+ to the 5G-grade communication systems [1]- [3]. From the networking perspective, these autonomous vehicles -and soon their large-scale connected fleets -represent a whole new class of intelligent mobile users that combine a number of heterogeneous data services [4], [5].…”

“…In addition, the capability of channel sensing (not supported in Releases 12 and 13) is introduced to Release 14 sidelink transmissions to avoid resource collisions among UEs [16], [17]. In Release 15, the 3GPP continues the evolution of Release 14 sidelink transmissions, and new functions such as carrier aggregation (CA), transmission diversity, and 64 quadrature amplitude modulation (QAM) are adopted to further enhance the throughput and reduce the latency [18].…”

Featuring direct communications between two user equipments (UEs) without signal relay through a base station, 3GPP sidelink transmissions have manifested their crucial roles in the Long-Term Evolution (LTE) Advanced (LTE-A) for public safety and vehicle-to-everything (V2X) services. With this successful development in LTE-A, the evolution of sidelink transmissions continues in 3GPP New Radio (NR), which renders sidelink an inevitable component as well as downlink and uplink. Targeting at offering low latency, high reliability and high throughout V2X services for advanced driving use cases, a number of new sidelink functions not provided in the LTE-A are supported in NR, including the feedback channel, grant-free access, enhanced channel sensing procedure, and new control channel design. To fully comprehend these new functions, this paper therefore provides essential knowledge of 3GPP NR sidelink transmissions, including the physical layer structure, resource allocation mechanisms, resource sensing and selection procedures, synchronization, and quality-of-service (QoS) management. Furthermore, this paper also provides performance evaluation to assess the gains brought from the new control channel design. As NR sidelink transmissions have been regarded as a foundation to provide advanced services other than V2X in future releases (e.g., advanced relay), potential enhancements are also discussed to serve the urgent demand in corresponding normative works.

“…For example, in [4] one can find a in-depth analysis of the enabling features of LTE for vehicular networks, with a focus on the standardization efforts. A review of the evolution of Release 14 (Rel-14) sidelink transmissions in Release 15 (Rel-15) may be found in [5], as well as the new functions supported in Rel-15 to further increase the throughput and reduce the latency. An insightful comparative for 5G between Vehicular Wi-Fi and C-V2X sidelink may be found in [6], which also tries to quantify the impact of the Physical layer (PHY) and Media Access Control layer (MAC) on the advantages and drawbacks found.…”

The connected car concept is gaining momentum from the point of view, not only of research, but also of standardization and industrial development. Today there are many options for connecting a vehicle, in terms of to whom and how. In addition to making use of any conventional cellular technology, and connecting the vehicle to a base station or infrastructure element, vehicles can connect wirelessly and directly to each other using different technologies, both from the Institute of Electrical and Electronics Engineers (IEEE) and from the 3rd Generation Partnership Project (3GPP). This article offers a rigorous and detailed review of the system architecture aspects involved in the support of vehicular communications by the 3GPP fifth-generation (5G) standard, with special emphasis on its most recent iteration: Release 16.
