5G NR TBS (Transport Block size) Calculator
This Page provides information about 5G NR TBS (Transport Block size) Calculator. Calculator is based on 3GPP 38.214 communication standards and allows you to calculate TBS depends on MCS (Modulation order, code rate), number of used PRB etc. Modulation Order and Code Rate are determined by tables: 38.214 Table 5.1.3.1-1 and Table 5.1.3.1-2. (depends on DCI, C-RNTI, MCS indexs).
Approximately TBS can be calculated using the formulas from 3GPP 38.214 chapter 5.1.3.2, where Ninfo – number of information bits:
