Anyone knows in which message in the L3 messages i can know the modulation?
Modulation information is communicated through DCI.
There is a message in L1 DL.
Check with TEMS, Mode report window Here you can find the below message.
Which might be helpful for you.
LTE L1 Downlink Info2 Message
PCell Modulation and its cnt can be seen…
But it’s a physical layer detail.
Looks like QPSK for either codewords.
