Abstract:
To determine an appropriate spatial resource for an uplink control channel. A user terminal includes a receiving section that receives a plurality of entries of information related to a spatial resource for an uplink control channel by using a higher layer, and receives specification information specifying at least one entry among the plurality of entries by using a downlink shared channel, and a control section that controls transmission of delivery acknowledgment information for the downlink shared channel, based on feedback timing of the delivery acknowledgment information and application timing of the spatial resource based on the specification information.
