1. A method of wireless communication performed by a user equipment (UE), the method comprising:
receiving, from a network unit via a single physical downlink control channel (PDCCH) communication, a configuration scheduling multiple physical downlink shared channel (PDSCH) communications;
receiving, from the network unit, a first subset of the multiple PDSCH communications;
transmitting, to the network unit via a first cell, a first physical uplink control channel (PUCCH) communication comprising acknowledgement/negative acknowledgement (ACK/NACK) feedback associated with the first subset of the multiple PDSCH communications after the receiving the first subset of PDSCH communications;
receiving, from the network unit, a second subset of the multiple PDSCH communications after transmitting the first PUCCH communication; and
transmitting, to the network unit, via a second cell, a second PUCCH communication comprising ACK/NACK feedback associated with the second subset of the multiple PDSCH communications, wherein the second cell is different from the first cell.
