Abstract :
One of the most significant challenges in
fulfilling the essential requirements for a 5G system is
achieving lower latency, which is the most dominant
aspect in 5G. Unlike previous generations, where there
was sufficient bandwidth for daily uses, today’s
applications, such as VANET and online gaming, demand
low latency. Control and location update information
depend more on latency than on throughput. In this
research, our focus will be on understanding and
addressing this crucial aspect. To begin, we will explore
the evolution to 5G NR (New Radio) based on the needs of
humans and how technology has strived to accomplish its
mission. A key aspect will be understanding the Key
Performance Indicators (KPIs) for evaluating a cellular
system’s performance. In-depth analysis will then be
conducted on the technical aspects related to latency.
Specifically, we will divide latency into different parts of
the network and concentrate on Radio Access Network
(RAN) latency. This will involve studying the impact of
waveform and frame flexibility structures, channels, and
duplex modes on latency, along with the role of
numerologies. By investigating these technical aspects, we
aim to contribute to the advancement of 5G systems,
ensuring they meet the stringent latency requirements of
modern applications. Ultimately, this research will pave
the way for better 5G implementations, benefiting various
industries and improving user experiences in critical
areas like VANET and online gaming.
