The need to support different kinds of UEs (e.g., for the Internet of Things (IoT)), services, and technologies is driving
the technology revolution to a high-performance and highly efficient 3GPP system. The drivers include IoT, Virtual
Reality (VR), industrial control, ubiquitous on-demand coverage, as well as the opportunity to meet customized market
needs. These drivers require enhancements to the devices, services, and technologies well established by 3GPP. The key
objective with the 5G system is to be able to support new deployment scenarios to address diverse market segments.
This document compiles requirements that define a 5G system.
The 5G system is characterised, for example, by:
Support for multiple access technologies
Scalable and customizable network
Advanced Key Performance Indicators (KPIs) (e.g., availability, latency, reliability, user experienced data rates,
area traffic capacity)
Flexibility and programmability (e.g., network slicing, diverse mobility management, Network Function
Resource efficiency (both user plane and control plane)
Seamless mobility in densely populated and heterogeneous environment
Support for real time and non-real time multimedia services and applications with advanced Quality of
