What is the difference between PUCCH Format 1B and 3? Can we use both format at a time?

Answer 1

Hi Bharath,

These format differentiates number of PUCCH bits and different multiplexing technique. Format 1B is used for 2CC Ca model and Format 3 is used for more than 2CC CA model.

PUCCH format can be used only one at a time, Both format cannot be used. Maybe for different UE different Format can be used simultaneously.
