1. A wireless transmit/receive unit (WTRU) comprising a processor configured to:
receive radio resource control signaling (RRC) comprising configuration information configuring a first Hybrid Automatic Repeat Request (HARQ) codebook associated with a first priority and a second HARQ codebook associated with a second priority, wherein the RRC signaling indicates that the first HARQ codebook is associated with a first sub-slot length for physical uplink control channel (PUCCH) feedback and that the second HARQ codebook is associated with a second sub-slot length for PUCCH feedback;
receive first downlink control information (DCI), the first DCI scheduling a first physical downlink shared channel (PDSCH) transmission, the first DCI indicating the first priority, wherein first HARQ feedback for the first PDSCH transmission is associated with the first HARQ codebook, and the first HARQ codebook is associated with the first priority;
receive second DCI, the second DCI scheduling a second PDSCH transmission, the second DCI indicating the second priority, wherein second HARQ feedback for the second PDSCH transmission is associated with the second HARQ codebook, and the second HARQ codebook is associated with the second priority;
determine, based on a first field in the first DCI, a first time for transmitting a first PUCCH transmission comprising the first HARQ feedback for the first PDSCH transmission, the first field indicating a first number of sub-slots according to the first sub-slot length associated with the first HARQ codebook;
determine, based on a second field in the second DCI, a second time for transmitting a second PUCCH transmission comprising the second HARQ feedback for the second PDSCH transmission, the second field indicating a second number of sub-slots according to the second sub-slot length associated with the second HARQ codebook;
determine that the first PUCCH transmission and the second PUCCH transmission at least partially overlap in time; and transmit the first PUCCH transmission and cancel at least a portion of the second PUCCH transmission based on the first priority being higher than the second priority;
transmit the first PUCCH transmission and cancel at least a portion of the second PUCCH transmission based on the first priority being higher than the second priority.
