Classification: CPC H | IPC H

Claim 26:
27. An apparatus for wireless communication performed at a user equipment (UE), comprising:
means for determining tri-state hybrid automatic repeat request (HARQ) feedback is configured based on a downlink (DL) carrier;
means for generating the tri-state HARQ feedback for at least one of a received physical downlink control channel (PDCCH) or a received physical downlink shared channel (PDSCH) on the DL carrier based on the determination that the DL carrier is configured with the tri-state HARQ feedback, wherein the tri-state HARQ feedback includes a discontinuous transmission (DTX) state that indicates the received PDCCH is not successfully decoded;
means for determining a codebook for the tri-state HARQ feedback based on a number of PDSCH occasions for which the tri-state HARQ feedback is generated or based on a downlink assignment indicator (DAI) in a DL grant received in the PDCCH: and
means for transmitting generated the tri-state HARQ feedback based on the codebook.
