5G New Radio (NR) development is part of continuous mobile broadband evolution process to meet the requirements of 5G as outlined by IMT-2020, similar to earlier evolution of 3G & 4G wireless networks.

5G NR 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.

The ITU-R is in process of developing the specifications for IMT-2020, in close collaboration with the whole gamut of 5G stakeholders along with the associated spectrum management and spectrum identification aspects.

3GPP submission to IMT 2020 (aka 5G) will include 5G New Radio (aka 5G NR) and LTE.

According to 3GPP 5G New Radio (NR) features will be phased as it will be not possible to standardize all in time for Rel-15 completion and early deployments.

Release 15 will aim at the first phase of expected deployments in 2020. It will address a more urgent subset of the commercial needs and is planned to be completed by Sep 2018.

Phase 2 is planned to be completed by Mar 2020. Rel-16 is targeted for the IMT 2020 submission and will address all identified usecases & requirements.

3GPP is still in process of ironing out 5G NR requirements. Some of the initial requirements are as following
