5G New Radio (NR) is the wireless standard that will become the foundation for the next generation of mobile networks. 5G NR development is part of continuous mobile broadband evolution process to meet the requirements of 5G as outlined by IMT-2020, similar to evolution of 3G and 4G wireless technologies. In past 3G and 4G connected people, where as future 5G will connect everything means 5G NR will be connecting our smartphones, cars, meters, wearables and etc. It aims to make wireless broadband same as of wireline with the fiber-like performance at a significantly lower cost-per-bit. With new levels of latency, reliability, and security, 5G NR will scale to efficiently connect the massive Internet of Things (IoT), and will offer new types of mission-critical services.
3GPP 5G NR standard, set to be published with 3GPP Release 15 and further developed to likely include new features, functions and services from there. NR will define the air interface that will support next-generation communication connectivity.
Based on the ongoing technical work, the 5G NR standard will consider standalone and non-standalone operation of NR cells. In non-standalone operation NR cell will uses LTE cell as the control plane anchor while in standalone operation NR cell will have full control plane functionality. Target use cases include Enhanced Mobile Broadband (eMBB) , Mission-Critical Services (MCS) and Massive Connected Device with ultra-reliable, low-latency communications in frequencies both above and below 6 GHz.
