Comprehensive Survey of Radio Resource Allocation Schemes for 5G V2X Communications

Abstract

In recent years, intelligent transportation systems, which provide safety and autonomous services on the road using the Internet and cellular technologies, have become increasingly important. Vehicles are equipped with sensors that can transmit data to other vehicles or infrastructure according to different types of services. In order to ensure robust connectivity for safety services, the transmission among vehicles requires low latency, high reliability, and high packet delivery ratio. With the increased number of vehicles, more frequency resources are needed to establish fast and reliable services. In the area of high vehicle density, the demand of frequency resources is increasing to establish stable connectivity in a short time. However, the amount of frequency resources is limited; the resource allocation scheme (RAS) should effectively assign a resource block to each user to ensure the quality of service. In this paper, we present a comprehensive survey of RASs for the 5G-based vehicular networks known as 5G V2X. We also discuss the challenges and opportunities for resource allocation in modern vehicular networks and present numerous promising future research directions.

Towards 6G V2X Sidelink: Survey of Resource Allocation—Mathematical Formulations, Challenges, and Proposed Solutions

“…Still, our survey focuses on advancements and challenges in the 6G V2X Sidelink, which can differ significantly. The survey [9] addresses resource allocation for 5G V2X vehicular networks, while our survey specifically examines new challenges and solutions unique to 6G V2X Sidelink. The research [10] concentrates on LTE-based Device-to-Device (D2D) communication for V2X services, classifying existing resource allocation algorithms.…”

Reuse Distance-Aided Resource Selection Mechanisms for NR-V2X Sidelink Communication

“…These studies demonstrated the effectiveness of open-source simulators and clarified the impact of NR-V2X on physical layer parameters and the RAM performance. In addition, the C-V2X RAM was comprehensively discussed in [ 22 , 23 ]. These works described and compared the RAM in different modes, while offering potential solutions for future challenges that the resource allocation algorithm should address.…”

Resource allocation for Vehicle‐to‐Everything communications: A survey

“…The work proposed in ref. [17] classified the proposed schemes into interference aware resource allocation scheme, GEO‐based resource allocation schemes, Time‐frequency resource allocation schemes and cluster‐based resource allocation schemes. For the authors in ref.…”

“…Recently, different previous works and surveys are interested in providing a global view of the radio resource and rate allocation in V2X communications such as the surveys given in refs. [15][16][17][18][19][20]. For the survey proposed in ref.…”

“…Indeed, an overview of D2D and V2X RRM proposed approaches is detailed based on metrics: QoS, secure outage probability, reliability and latency, overhead signalling, interference and achievable rate. Similarly, the two papers [17], and [18] are interested in RRM in 5G V2X networks. In these two papers, authors considered a part of RRM that is resource allocation in V2X and given a classification of the different proposed schemes.…”
