1. A terminal comprising:
a receiver that, for a plurality of Physical Downlink Shared Channels (PDSCHs) from a plurality of Transmission/Reception Points (TRPs), receives a higher layer parameter indicating one of a first Acknowledgement (ACK)/Negative Acknowledgement (NACK) feedback for transmitting an individual Hybrid Automatic Repeat reQuest (HARQ)-ACK to each TRP and a second ACK/NACK feedback for transmitting a HARQ-ACK corresponding to the plurality of PDSCHs from the plurality of TRPs to one TRP;
a processor that, if, in an active Downlink Bandwidth Part (DL BWP) of a serving cell, a COntrol REsource SET (CORESET) pool index is not provided or a CORESET pool index with value 0 is provided for one or more first CORESETs and a CORESET pool index with value 1 is provided for one or more second CORESETs, and if the second ACK/NACK feedback is indicated by the higher layer parameter for the serving cell, determines, based on a time domain, an index of Physical Downlink Control Channel (PDCCH) monitoring occasions associated with the second ACK/NACK feedback, and determines indexing of the PDCCH monitoring occasions in ascending order of start times of CORESETs associated with the PDCCH monitoring occasions; and
a transmitter that transmits the HARQ-ACK corresponding to the plurality of PDSCHs by using a HARQ-ACK codebook determined based on the indexing.
