1. A network equipment (NE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the NE to:
generate a common Downlink Assignment Indicator (DAI) value for multiple Physical Downlink Control Channel (PDCCH) transmissions, wherein the multiple PDCCH transmissions are used to transmit first Downlink Control Information (DCI) that schedules a common Physical Downlink Shared Channel (PDSCH) transmission, and the common DAI value is generated based on a first reference PDCCH, and wherein the first reference PDCCH is one of the multiple PDCCH transmissions;
transmit the first DCI that schedules the common PDSCH transmission using the multiple PDCCH transmissions, wherein each of the multiple PDCCH transmissions includes the common DAI; and
receive a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) codebook with feedback information bits ordered based on a second reference PDCCH, wherein the second reference PDCCH is one of the multiple PDCCH transmissions.
