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. But there can be some cases where transmitting signals from two different antenna ports experience radio channels having common properties. In such cases the antenna ports said to be Quasi-Colocation (QCL).

Here you can find a detailed explanation:
