Ok, but one thing:
What is CDL A B and C for NLOS?
Those have different angles and which one is best for model for CDL.
I just want to know this part only.

There’s a lot of debate regarding which channel model to use in link budget.
Ericsson LB is based on TDL advanced which is a modified version to adapt to CDL.

So, the modeling can be chosen depending on the customer requirements.
Thanks for your help! :wink:
