Uncommon card · No. 129262

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 and operates across both sub-6 GHz (FR1) and millimeter-wave (FR2) frequency bands. Standardized initially in 3GPP Release 15, the specification builds upon the orthogonal frequency-division multiplexing (OFDM) waveform principles established in the 4G LTE standard while introducing scalable numerology, advanced beamforming, and flexible slot-based frame structures to support enhanced mobile broadband, ultra-reliable low-latency communication, and massive machine-type communications. 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...
