elated to higher data rates, user den- sity, user mobility, and coverage. Higher data rates are driven by the increasing use of data for services such as streaming (e.g., video, music, and user generated content), interactive services, and some IoT applications. These services have stringent requirements for user experienced data rates and end-to-end latency in order to guarantee good user experience. In addition, increased coverage in densely populated areas such as sports arenas, urban areas, and transportation hubs is essential for nomadic and mobile users. The new KPIs on traffic and connection density would enable transport of large amount of user traffic per area (traffic density) and transport of data for a large number of connections (connection density). A large group of UEs are expected to support variety of services which exchange either a very large (e.g., streaming video) or very small (e.g., data burst) amount of data. The 5G systems are designed to manage this variability in an extremely resource and energy efficient manner. All of these scenarios introduce new requirements for indoor and outdoor deployments, local area connectivity, high user density, wide-area connectivity, and UEs travelling at high speeds. Another aspect of 5G KPIs includes requirements for various com- binations of latency and reliability, as well as higher position determination accuracy. These KPIs are further driven by support for commercial and public safety services. Support for mMTC presents several new requirements in addition to those for the eMBB use cases. The proliferation of the connected things introduces a need for significant improvements in resource efficiency in all system components (e.g., UEs, IoT devices, radio access network, core network). The 5G systems are intended to extend their capabilities to meet KPIs required by emerging mission-critical applications. For these advanced applications, the requirements, such as data rate, reliability, latency, communication range, and speed, are made more stringent.
