## 2 Literature Review  
Previous research on C-V2X communication and sidelink resource allocation has primarily focused on static allocation techniques, semi-persistent scheduling and interference management. [PERSON] et al. [17] explores advancements in sidelink (SL) Device-to-Device (D2D) communication, crucial for enhancing 5G Vehicle-to-Everything (V2X) communication. It addresses resource scheduling and allocation in various sidelink D2D modes for both scenarios with and without coverage. Through simulations, the authors focus on performance while concentrating on collision probability and changing important factors such as resource reselection interval (RRI) and resource selection window [18]. The difficulties in delivering ultra-reliable, low-latency communications in 5G V2X are also addressed. Instead of D2D communication, our research is focused on expanding V2X communication domain. We are focusing on the complex relationships between generation time, speed and distance, and their effects on collision probability in a given geographic area. A recent study by [PERSON] et al. [19] examined the role of channel coding schemes in 5G-NR V2X communication, comparing Turbo Codes, Low-Density Parity-Check (LDPC) and Polar Codes under different stochastic propagation models, including line-of-sight (LOS), non-line-of-sight (NLOS) and vehicle-blocked Non-Line-of-Sight (NLOSv) scenarios. The authors demonstrated that Turbo Codes outperform LDPC and Polar Codes for small-frame V2X transmissions, particularly in low and mid signal to noise ratio (SNR) regions, due to their superior error-correcting capabilities. However, at high SNR values, Polar Codes demonstrated better Bit Error Rate (BER) performance. These findings suggest that choosing the appropriate coding scheme for V2X transmissions depends on network conditions, traffic density and environmental factors. [PERSON] et al. [20] examines the advancement of V2X services and the progression of 3 GPP standardization beyond 5G Mode 1. Platooning, advanced driving, sensor connectivity and remote driving user cases are highlighted as examples of how NR sidelink has been developed in 5G Mode 2 to directly enable V2X services. In order to improve feedback and resource management for various types of V2X traffic, this study outlines the changes required in network architecture, physical layer design using Cyclic Prefix Orthogonal Frequency-Division Multiplexing (CPOFDM) and introduces an overlapping zone concept in the protocol layer. In our study, we are focusing on the resource allocation based on time-domain sidelink using Mode 4. [PERSON] et al. [21] addresses autonomous sidelink resource scheduling in C-V2X and its challenges, including collision probability and performance issues for low-latency, high-reliability applications. To enhance performance, the authors propose a reservation mechanism as a supplement to the standard sensing-based semi-persistent scheduling (SPS) algorithm, primarily for C-V2X sidelink Mode 4. The reservation mechanism significantly improves performance in congested scenarios and at the fringe of communication ranges. Notably, the authors emphasize that making reservations well in advance, ideally at least one second prior to actual resource use, leads to the best performance outcomes. In our study, we focused on the generation time of the packets and the distances and speeds between UEs. Large-scale multiple-input multiple-output (LS-MIMO) technology has been studied for its spectral and energy efficiency in wireless communication. [PERSON] et al. [22] examined channel aging effects, showing how outdated channel information and Doppler shift degrade precoding efficiency and bandwidth allocation. These findings align with our work, as adaptive resource allocation in 5G NR sidelink is essential for reducing collision probability and optimizing transmission reliability in dynamic environments.
