Zusammenfassung: | Systems, methods, and instrumentalities are disclosed that may be associated with HARQ-ACK codebook adaptations. A WTRU) may be configured with multiple physical uplink channels, e.g., physical uplink control channels (PUCCHs), in a slot. Each physical uplink channel may have a respective HARQ-ACK codebook. In examples, the WTRU may determine that a first physical uplink channel and a second physical uplink channel overlap in a slot. In such a case, the WTRU may determine that a first HARQ-ACK codebook associated with the first physical uplink channel has a higher priority than a second HARQ-ACK codebook associated with the second physical uplink channel. The WTRU may transmit the first HARQ-ACK codebook on the first physical uplink channel in the slot. The WTRU may send part of the second HARQ-ACK codebook in the slot and part of the second HARQ-ACK codebook in a subsequent slot (e.g., a next slot, a future slot, etc.). |
