Which CQI table should i choose for CQI value from telephony manager api

Question

I am getting cqi value (Get channel quality indicator Reference: 3GPP TS 136.213 section 7.2.3.) from telephony manager, but now i am confused which exact table should i choose for 4g network and 5g network. In the docs they have mentioned about 3 tables each for 4g and 5g. I want to show the respective modulation for the cqi value from the telephony manager api.

Answer 1

You could use the getCqiTableIndex/getCsiCqiTableIndex methods to get the CQI table index for LTE/5G.

For LTE the tables are defined in 3GPP 36.213 - section 7.2.3

For 5G the tables are defined in 3GPP 38.214 - section 5.2.2.1
