1. A terminal comprising:
a transmitter that transmits capability information indicating whether the terminal supports a physical downlink shared channel (PDSCH) using downlink control information (DCI) transmitted from each of a plurality of transmit/receive points (TRPs);
a receiver that receives the DCI transmitted from each of the plurality of TRPs in a same serving cell and receives the PDSCH scheduled by the DCI; and
a processor that controls, based on a counter downlink assignment indicator (DAI) and a total DAI, the counter DAI and the total DAI being jointly counted between the plurality of TRPs and included in the DCI, generation of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the PDSCH,
wherein the counter DAI is counted first in an ascending order of an index indicating the plurality of TRPs, then in an ascending order of a serving cell index, and then in an ascending order of a physical downlink control channel (PDCCH) monitoring occasion index, and
the total DAI is a total number of pairs of a TRP, a serving cell, and a PDCCH monitoring occasion.
