5G NR Resource Grid Visualizer is an interactive tool that renders the complete time-frequency structure of a 5G New Radio radio frame (10ms) across configurable bandwidths from 5–100 MHz and subcarrier spacings of 15/30/60/120 kHz, automatically computing the correct number of resource blocks per 3GPP TS 38.101. It maps all major physical channels and signals — SSB (PSS/SSS/PBCH), CORESET 0, PDCCH, PDSCH, PUSCH, PUCCH, PRACH, and both DL/UL DMRS — onto the resource grid at t

The Physical Downlink Control Channel (PDCCH) is a cornerstone of 5G New Radio (NR) and 4G Long-Term Evolution (LTE) systems, serving as...
