In Release 14, the 3rd Generation Partnership Project (3GPP) introduced Cellular Vehicle-to-Everything (C-V2X) mode-4 as a novel disruptive technology to support sidelink vehicular communications in out-of-coverage scenarios. C-V2X mode-4 has been engineered to operate in a distributed manner, wherein vehicles autonomously monitor the received power across sidelink subchannels before selecting one for utilization. By means of such an strategy, vehicles attempt to (i) discover and (ii) reserve…

Decentralized Subchannel Scheduling for C-V2X Mode-4: A Non-Standard Configuration for CAM Retransmissions
This work assumes the existence of a primary sub-band that supports semi-persistently reserved subchannels (as specified by 3GPP) and also considers that there exist auxiliary sub-bands that convey random re-transmissions in order to improve reception reliability.
Full duplex-aided Sensing and Scheduling in Cellular-V2X Mode 4
This paper proposes to provide vehicles with on-board full-duplex transceivers and harness this capability to make the sensing phase more accurate, to make a more informed resource reselection decision, and to enhance packet decoding while transmitting.
Performance Evaluation of NOMA for Sidelink Cellular-V2X Mode 4 in Driver Assistance System With Crash Warning
SPS-NOMA is expected to be the next generation sidelink C-V2X as the extended mode 4 of sidelink cellular-vehicle-to-everything mode 4, in driver assistance systems with a crash warning.
Piggyback-Based Distributed MAC Optimization for V2X Sidelink Communications
This paper introduces Age of Information (AoI) to evaluate the status update performance of C-V2X and proposes a piggyback-based collaboration method that exhibits better performance than the current schemes, both in terms of AoI and transmission reliability.
Asynchronous Traffic on the Sidelink of 5G V2X
The suitability to DENMs of the resource selection algorithm specified for CAMs in Release 14 is first investigated, before analyzing some suggested parameter adjustments for Release 16, and elaborating on their most suitable tuning under different simulation settings.
ATOMIC: Adaptive Transmission Power and Message Interval Control for C-V2X Mode 4
ATOMIC, an Adaptive Transmission pOwer and Message Interval Control scheme for C-V2X Mode 4, in which each vehicle utilizes real-time channel sensing and neighbor information to reduce channel contention for improved reliability and latency is proposed.
Configuration of the CV 2 X Mode 4 Sidelink PC 5 Interface for Vehicular Communications
The 3GPP has released the C-V2X standard to support V2X (Vehicle-to-Everything) communications using the LTE sidelink PC5 interface. This standard includes two modes of operation, and this study
LTE-V2X Mode 3 scheduling based on adaptive spatial reuse of radio resources
The proposed scheduling scheme, referred to as DIRAC (aDaptive spatIal Reuse of rAdio resourCes), is validated analytically and its performance is evaluated through system level simulations and shows that it outperforms existing LTE-V2X Mode 3 and Mode 4 scheduling schemes and ensures a more scalable and stable network operation as the channel load and congestion increases.

This work proposes a novel Mode 4 resource-allocation algorithm, called SNB (Shake-and-Back), which either randomly selects and uses a resource each time or uses a selected resource based on its decoding state to avoid consecutive message losses.
Impact of the Generation Interval on the Performance of Sidelink C-V2X Autonomous Mode
An analysis of how a misalignment between packet generation and resource allocation affects the system performance and insights into how to design the parameter settings to improve the performance are provided.


System Level Evaluation of LTE-V2V Mode 4 Communications and Its Distributed Scheduling
This paper presents the first evaluation of the performance and operation of this protocol under realistic traffic conditions in urban scenarios, and demonstrates that further enhancements should be investigated to reduce packet collisions.
Subchannel allocation for vehicle-to-vehicle broadcast communications in mode-3
Four types of conditions that are of forceful character for attaining QoS-aware conflict-free allocations have been identified and a surrogate relaxation of the problem is proposed that does not affect optimality provided that certain requisites are satisfied.
Localization-based resource selection schemes for network-controlled LTE-V2V
This paper focuses on network-controlled resource management based on the knowledge of the position of vehicles by the network and an algorithm based onThe concept of reuse distance is proposed to reach the maximum communication distance with a given quality of service.
On the Performance of IEEE 802.11p and LTE-V2V for the Cooperative Awareness of Connected Vehicles
Results show that LTE-V2V allows us to maintain the required quality of service at even double or more the distance than IEEE 802.11p in moderate traffic conditions, however, due to the half-duplex nature of devices and the structure of LTE frames, it shows lower capacity if short distances and very high vehicle density are targeted.
Graph-based resource allocation with conflict avoidance for V2V broadcast communications
This research has envisaged a solution based on a bipartite graph, where vehicles and spectrum resources are represented by vertices whereas the edges represent the achievable rate in each resource based on the signal-to-interference-plus-noise ratio (SINR) that vehicles perceive.
