Abstract:
A terminal according to an aspect of the present disclosure includes: a receiving section that receives downlink control information for releasing a plurality of semi-persistent schedulings (SPSs); and a control section that performs control of including a valid Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) corresponding to the downlink control information at at least one of a plurality of positions of HARQ-ACKs corresponding to downlink shared channel (Physical Downlink Shared Channel (PDSCH)) reception of the plurality of SPSs in a semi-static HARQ-ACK codebook. According to an aspect of the present disclosure, the HARQ-ACK codebook can be appropriately determined even when joint SPS release is used.
