User terminal and radio communication method

1. A terminal comprising:

a receiver 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 processor that controls transmission of HARQ information for the downlink shared channel, based on feedback timing of the HARQ information and application timing of the spatial resource based on the specification information,

wherein the information related to the spatial resource for the uplink control channel associated with the at least one entry is applied to a plurality of uplink control channels.

2. The terminal according to claim 1 , wherein the processor determines whether or not to apply the spatial resource specified by the specification information to the transmission of the HARQ information, based on a relationship between the feedback timing and the application timing.

3. The terminal according to claim 2 , wherein the processor determines whether or not to transmit the HARQ information, based on a relationship between the feedback timing and the application timing.

4. The terminal according to claim 1 , wherein the processor determines different feedback timing, based on whether or not the downlink shared channel includes the specification information.

5. The terminal according to claim 1 , wherein when downlink control information used to schedule the downlink shared channel does not include an indication of the feedback timing, the processor applies the spatial resource configured in advance to the transmission of the HARQ information.

6. A radio communication method for a terminal, the radio communication method comprising:

receiving a plurality of entries of information related to a spatial resource for an uplink control channel by using a higher layer, and receiving specification information specifying at least one entry among the plurality of entries by using a downlink shared channel; and

controlling transmission of HARQ information for the downlink shared channel, based on feedback timing of the HARQ information and application timing of the spatial resource based on the specification information,

wherein the information related to the spatial resource for the uplink control channel associated with the at least one entry is applied to a plurality of uplink control channels.

7. The terminal according to claim 2 , wherein the processor determines different feedback timing, based on whether or not the downlink shared channel includes the specification information.

8. The terminal according to claim 3 , wherein the processor determines different feedback timing, based on whether or not the downlink shared channel includes the specification information.

9. The terminal according to claim 2 , wherein when downlink control information used to schedule the downlink shared channel does not include an indication of the feedback timing, the processor applies the spatial resource configured in advance to the transmission of the HARQ information.

10. The terminal according to claim 3 , wherein when downlink control information used to schedule the downlink shared channel does not include an indication of the feedback timing, the processor applies the spatial resource configured in advance to the transmission of the HARQ information.

11. The terminal according to claim 4 , wherein when downlink control information used to schedule the downlink shared channel does not include an indication of the feedback timing, the processor applies the spatial resource configured in advance to the transmission of the HARQ information.
