Systems, devices, and techniques for wireless communications are described. A described technique includes receiving, by a user equipment (UE) from one or more Transmission and Reception Points (TRPs), a physical downlink shared channel (PDSCH) transmission; determining, by the UE for a physical uplink control channel (PUCCH) carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK), a TRP index in accordance with a control resource set (CORESET) scheduling the PDSCH transmission; and transmitting, by the UE via the PUCCH, HARQ-ACK information based on the receiving of the PDSCH transmission in accordance with the TRP index.
