CORESET/PDCCH Calculator
Calculate 5G NR Control Resource Set (CORESET) capacity, CCE resources, and PDCCH configuration.
CORESET Capacity Calculator
Calculate total REGs, CCEs, and maximum PDCCHs for a CORESET
Frequency domain resources (6-276 RBs)
Time domain duration
Subcarrier spacing
Aggregation Level Capacity
Calculate bit capacity for different aggregation levels
Number of CCEs per PDCCH
Account for DMRS overhead (3 REs per REG)
Note: PDCCH always uses QPSK modulation (2 bits/symbol). Higher aggregation levels provide more robust transmission for poor radio conditions.
RB Requirement Calculator
Calculate minimum RBs needed for multiple DCIs
Time domain duration for the CORESET
Tip: Add multiple DCIs with different aggregation levels to calculate the total RB requirement. The calculator will round up to the nearest multiple of 6.
CORESET 0 Configuration
Calculate CORESET 0 parameters for initial access (SIB1)
SSB subcarrier spacing
pdcch-ConfigSIB1 (0-15)
Minimum channel bandwidth
About CORESET 0: Special pre-configured CORESET used for scheduling SIB1. Parameters are derived from MIB (3GPP TS 38.213 Section 13, Tables 13-1 to 13-10).
