Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided at the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started at the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

In the new air interface technology, the application of the internet of things is an important component. Although some new features have been introduced in Release 15 and 16 versions (Release 16) to support different internet of things application scenarios, such as Ultra-reliable low latency communications (URLLC, ultra-reliable and Low Latency Communications) and industrial physical networks (IIoT, industrial Internet of Things), standard support is still required for other application scenarios, such as wearable devices, surveillance videos, etc. Based on the above background, the Study was started at Release 17 (Release 17) with SI (Study Item) having passed the reduced capability (RedCap, reduced Capability) (also referred to as NR-Lite in the earlier stage) at the 3gpp ran#86 full meeting.
