5G New Radio (NR) development is part of continuous 3GPP mobile standard 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 equivalent to the fiber-like performance of wireline systems at a significantly lower cost-per-bit. With new levels of latency, reliability, and security, 5G NR will scale efficiently to connect the massive Internet of Things (IoT) ecosystem, and will offer new types of mission-critical services.
According to 3GPP, 5G New Radio (NR) features will be phased as it will not be possible to standardize all the protocols in time for Rel-15 completion and early deployments.
3GPP aims to complete initial 5G specifications with Release 15 by mid-2018 whereas Release 16 is targeted by end of 2019. Release 15 will enable the first phase of expected deployments in 2020.
Release 15 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.
Some of the initial 5G NR requirements are as follows:
