1. A method comprising:
receiving, from one or more transmission and reception points (TRPs), a physical downlink shared channel (PDSCH) transmission, the PDSCH transmission comprising a first PDSCH transmission and a second PDSCH transmission, wherein the first PDSCH transmission is associated with a first control resource set (CORESET) scheduling the first PDSCH transmission, and wherein the second PDSCH transmission is associated with a second CORESET scheduling the second PDSCH transmission;
determining, for a first hybrid automatic repeat request-acknowledgement (HARQ-ACK) associated with the first CORESET, a first TRP index value in accordance with the first CORESET scheduling the first PDSCH transmission;
determining, for a second HARQ-ACK associated with the second CORESET, a second TRP index value in accordance with the second CORESET scheduling the second PDSCH transmission;
determining, that the first HARQ-ACK is scheduled to be transmitted in a first a physical uplink control channel (PUCCH) transmission;
determining that the first PUCCH transmission overlaps in time with a first physical uplink shared channel (PUSCH) transmission associated with the second TRP index value;
determining to drop the first PUCCH transmission or the first PUSCH transmission; and
transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value or the second TRP index value, wherein the transmitting comprises using the first TRP index value and the second TRP index value for HARQ-ACK codebook construction.
