Decentralized Subchannel Scheduling for C-V2X Mode-4: A Non-Standard Configuration for CAM Retransmissions [article]

Luis F. Abanto-Leon
2019 arXiv   pre-print
In Release 14, 3GPP introduced a novel paradigm known as cellular vehicle–to–everything (C-V2X) mode-4 to specifically support vehicular communications in scenarios without network coverage.  ...  The selected subchannel is utilized by the vehicle for a short period of time before releasing it to select another subchannel.  ...  Section II describes the concept of semi-persistent scheduling (SPS) for C-V2X mode-4. Section III explains in detail the proposed decentralized scheduling scheme.  ...

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

Thien Thi Thanh Le, Sangman Moh
2021 IEEE Access  
ACKNOWLEDGMENT The authors thank the editor and anonymous referees for their comments, which were helpful for improving the quality of this paper.  ...  When a vehicle has packet to transmit, a resource selection is triggered. A vehicle performs resource selection in a resource selection window for periodic traffic transmission as in C-V2X mode 4.  ...  -MAIN FEATURES: The reliability of the data is improved via one blind retransmission in 3GPP Release 14 mode 3 and mode 4.  ...

Reliable Groupcast For NR V2X

Yan-Teng Kuo, Wen-Di Shen, Hung-Yu Wei
2021 IEEE Access  
We formulate a retransmission UE selection problem to maximize the group packet reception ratio (GPRR) for NR V2X distributed groupcast.  ...  In general, the group size for vehicles is limited due to the high-reliability requirement. In this paper, we present reliable blind retransmission for NR V2X groupcast.  ...  In this mode, each UE autonomously selects its resources, similar to C-V2X sidelink mode 4 C.  ...
