Simply put, it is a secially designed downlink only channel which carries ACK or NACK for the PUSCH received by the network. Uplink case they just used PUCCH for carrying ACK/NACK for each PDSCH it recieved. Why don't we use PDCCH for ACK/NACK on network side. cindy laughrea

"Splet– ACK: the UE does not perform any UL (re)transmission and keeps the data in the HARQ buffer. A PDCCH is then required to perform a retransmission i.e. a non-adaptive retransmission cannot follow. – For asynchronous adaptive HARQ, HARQ feedback is not sent, except for BL UEs and UEs in enhanced coverage.
