5G NR MCS and TBS Tables Explained

This page explains the 5G NR MCS (Modulation and Coding Scheme) Table and the 5G NR TBS (Transport Block Size) Table as defined in 3GPP TS 38.214.

Introduction:

5G NR (New Radio) is the latest cellular wireless technology, adhering to 3GPP specifications, much like LTE. The complete protocol stack for both the UE (User Equipment) and gNB (Base Station) is detailed in the 38 series of documents. MCS and TBS are crucial elements used within the physical layer of the 5G NR system.
