34、d in the document. Introduction 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 contro

35、l, 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 dive

36、rse 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, us

37、er experienced data rates, area traffic capacity) - Flexibility and programmability (e.g., network slicing, diverse mobility management, Network Function Virtualization) - Resource efficiency (both user plane and control plane) - Seamless mobility in densely populated and heterogeneous environment -

39、uding a UE, NG-RAN, and 5G Core network.

The 5G system shall efficiently support service discovery mechanisms where UEs can discover, subject to access rights: - status of other UEs (e.g., sound on/off); - capabilities of

46、other UEs (e.g., the UE is a relay UE) and/or; - services provided by other UEs (e.g., the UE is a colour printer). The 5G system shall be able to minimise the amount of wireless backhaul traffic (e.g., consolidating data transmissions to 1 larger rather than many smaller), when applicable (e.g., pr

47、oviding service in an area subject to power outages). The 5G system shall support small form factor UEs with single antenna.

User plane should be more efficient for 5G to support differentiated requirements.
