1. A wireless communication method, comprising:
receiving, by a network node, a data transmission from a communication node; and
transmitting to the communication node a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook in a downlink feedback information (DFI) in a downlink control information (DCI), wherein the HARQ-ACK codebook is based on the received data transmission,
wherein a physical downlink control channel (PDCCH) includes the DFI and a DCI format associated with the DCI, and
wherein the PDCCH includes one or more padded zeros in response to a number of bits of the DFI being less than another number of bits corresponding to the DCI format associated with the DFI.
