I know UE reports three parameters known as CQI (Channel Quality Indicator) , PMI (Pre-coding Matrix Index) and RI (Rank indicator).
Is it necessary all these three parameters should be reported and all of them have inter dependency and eNodeB considers all the parameters to take its decision ?
I am expecting answer which gives me the complete understanding of all these parameters such as
- When eNodeB configures all these parameters ?
- Can it be configured independently or together ?
- What an eNodeB does after receiving all these parameters ?
