Background

In the ever-evolving landscape of wireless communication, 5G technology stands as a transformative force, promising unparalleled speed, ultra-low latency, and massive connectivity. Among its groundbreaking features is 5G Sidelink, a direct communication method that enables devices to communicate with each other without relying on network infrastructure. This peer-to-peer communication capability revolutionizes how devices interact in various scenarios, including public safety, automotive, and IoT applications. 

5G Sidelink, also known as PC5 interface or Device-to-Device (D2D) communication, allows direct communication between devices within proximity. This feature is particularly vital in situations where network coverage is inadequate or in environments requiring real-time, reliable communication, such as:

• Public Safety: Enabling first responders to communicate directly during emergencies, even in the absence of network infrastructure.

• Automotive: Facilitating Vehicle-to-Everything (V2X) communication for enhanced road safety and autonomous driving.

• IoT: Allowing IoT devices to interact seamlessly in smart cities and industrial applications.
