Which are the Physical signals sent in UCI?

Question

I am looking for physical layer functions. Precisely would also be fine. Need to be more exact in answer.
Thanks in advance.

Answer 1

Not sure about the question just made a guess -
UCI means Uplink Control Information which is carried by PUCCH or PUSCH. UCI is the counter part of DCI, but the information/role of UCI is very small comparing to DCI.

The information carried by UCI is mainly following three
1. SR (Scheduling Request)
2. HARQ ACK/NACK
3. CQI
