Enhanced mobile broadband (eMBB) — This scenario is still the most important usage scenario that addresses human-centric communications. eMBB use cases have various challenges. For example, hot spots require higher data rates, higher user density, and a need for high capacity. Wide area coverage stresses mobility and seamless user experience with lower requirements on data rate and user density.

Massive machine type communications (mMTC) — This scenario addresses pure machine-centric use cases characterized by a large number of connected devices. Typically, the data rate requirement of mMTC applications is low. However, the use cases demand a high connection density locally, low cost, and long battery life.

Ultra reliable and low latency communications (URLLC) — This scenario covers both human-centric communication and critical machine-type communication (C-MTC) that demand low latency, reliability, and high availability. Typical URLLC use cases include 3-D gaming, self driving cars, mission-critical applications, remote medical surgery, and wireless control of industrial equipment.
