5G NR
5G NR (5G New Radio) is a radio access technology (RAT) developed by the 3rd Generation Partnership Project (3GPP) for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G networks. It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth generation) long-term evolution (LTE) standard.
The 3GPP specification 38 series provides the technical details behind 5G NR, the successor of LTE.
The study of 5G NR within 3GPP started in 2015, and the first specification was made available by the end of 2017. While the 3GPP standardization process was ongoing, the industry had already begun efforts to implement infrastructure compliant with the draft standard, with the first large-scale commercial launch of 5G NR having occurred in the end of 2018. Since 2019, many operators have deployed 5G NR networks and handset manufacturers have developed 5G NR enabled handsets.
5G NR uses frequency bands in two broad frequency ranges:
gNodeB or gNb (Next Generation Node B) means a 5G base station. It transmits radio data to and receives radio data from user equipment. Its coverage area is called a cell. The gNodeB may be a tower.
A "Non-Standalone" (NSA) gNodeB is built on an existing LTE (4G) base station (eNodeB or eNB).
Ooredoo was the first carrier to launch a commercial 5G NR network, in May 2018 in Qatar. Other carriers around the world have been following suit.
In 2018, 3GPP published Release 15, which includes what is described as "Phase 1" standardization for 5G NR. The timeline for Release 16, which will be "5G phase 2", follows a freeze date of March 2020 and a completion date of June 2020, Release 17 was originally scheduled for delivery in September 2021. but, because of the COVID-19 pandemic, it was rescheduled for June 2022.
