QCL Quasi-Colocation Concept in 5G NR

Hello Experts,

Any good reference to understand QCL TCI concept in 5G?
To help visualise the concept.

Hello @Shalab_Tripaathi,

Two signals transmitted from same antenna port shall experience the same radio channel, where as transmitting it from two different antenna ports shall experience different radio conditions.
