Abstract

The 5G New Radio (5G NR) mobile standard provides considerable bandwidth and latency advantages compared to its predecessor, 4th Generation Long Term Evolution (4G LTE). The 5G NR standard defines flexible numerologies, giving variable Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) subcarrier spacing and cyclic prefix options. This work proposes a Radio Frequency System on Chip (RFSoC) single chip transmitter solution with runtime reconfigurable numerology, simulating a deployable Radio Unit (RU) which could support both sub-6 GHz and mmWave 5G NR transmission.
