The present document covers Critical Communications. The main areas where the 3GPP system falls short in meeting
the requirements of Critical Communications is latency, reliability, and availability. These requirements can be met
with an improved radio interface, optimised architecture, and dedicated core and radio resources. Other requirements
having emerged in TR 22.891
, such, as, high bandwidth, high connection density, low complexity, low power
consumption, and massive number of devices, are often irrelevant for Critical Communications.
