NR Throughput Calculator

Approximate peak data rate per TS 38.306 §4.1.2 — the formula UE capability data rates are based on. Add carriers for CA, set layers, modulation and scaling factor.

Component carriers

TDD DL share %

TDD share applies to TDD carriers only (FDD/SDL/SUL carriers use all slots). UL share = 100 − DL share minus nothing for guard — set it from your pattern, e.g. DDDSU ≈ 74 % DL symbols.

Peak data rate

How it is computed

R_max = 948/1024; T_s^μ = 10⁻³/(14·2^μ) (normal CP); N_PRB from TS 38.101-1/-2 Table 5.3.2-1; OH = 0.14 FR1 DL, 0.18 FR2 DL, 0.08 FR1 UL, 0.10 FR2 UL. This is the theoretical peak with every slot scheduled at the top MCS — real throughput is lower (TDD pattern, control/RS overhead beyond OH, link quality).
