Abstract:
A user terminal according to an aspect of the present disclosure includes a control section that generates a Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) codebook containing only HARQ-ACK corresponding to a semi-persistent scheduling (SPS) downlink shared channel (Physical Downlink Shared Channel (PDSCH)), so that HARQ-ACK bits corresponding to the PDSCH each SPS are ordered in accordance with a given rule, and a transmitting section that transmits an HARQ-ACK information bit corresponding to the HARQ-ACK codebook by using an uplink control channel resource based on an SPS corresponding to HARQ-ACK at a specific location in the order. According to an aspect of the present disclosure, it is possible to feed back HARQ-ACK appropriately even when a plurality of SPSs is utilized.
