User terminal and radio communication method
The present invention is designated to appropriately control intra-slot frequency hopping of an uplink channel/signal. A user terminal of the present invention includes a transmitting section that transmits an uplink data channel in one slot or over a plurality of slots, a receiving section that receives information related to frequency resource to which the uplink data channel is to be mapped, and a control section that controls frequency hopping of the uplink data channel in each slot, based on the information related to the frequency resource.
1. A terminal comprising:
a receiver that receives downlink control information that includes predetermined bits,
wherein a number of the predetermined bits of the downlink control information is derived based on a bandwidth of an uplink bandwidth part; and
a processor that controls intra-slot frequency hopping of an uplink shared channel based on a frequency offset indicated by using the predetermined bits in the downlink control information,
wherein the number of bits of the predetermined bits is 1 when the bandwidth of the uplink bandwidth part is smaller than a predetermined value, or 2 when the bandwidth of the uplink bandwidth part is equal to or greater than the predetermined value.
2. The terminal according to claim 1 , wherein the processor also controls the intra-slot frequency hopping based on a frequency resource for the uplink shared channel derived by using bits other than the predetermined bits of a predetermined field in the downlink control information.
3. The terminal according to claim 1 , wherein the frequency offset is a frequency offset in resource blocks between a first hop and a second hop.
4. The terminal according to claim 1 , further comprising a transmitter that transmits the uplink shared channel in a single slot or a plurality of slots.
5. A radio communication method in a terminal, the radio communication method comprising:
receiving downlink control information that includes predetermined bits,
wherein a number of the predetermined bits of the downlink control information is derived based on a bandwidth of an uplink bandwidth part; and

wherein the number of bits of the predetermined bits is 1 when the bandwidth of the uplink bandwidth part is smaller than a predetermined value, or 2 when the bandwidth of the uplink bandwidth part is equal to or greater than the predetermined value.
6. A radio base station comprising:
a transmitter that transmits downlink control information that includes predetermined bits,
wherein a number of the predetermined bits of the downlink control information is derived based on a bandwidth of an uplink bandwidth part; and
a processor that controls a reception of an uplink shared channel to which intra-slot frequency hopping is applied based on a frequency offset indicated by using the predetermined bits in the downlink control information,
wherein the number of bits of the predetermined bits is 1 when the bandwidth of the uplink bandwidth part is smaller than a predetermined value, or 2 when the bandwidth of the uplink bandwidth part is equal to or greater than the predetermined value.
7. The terminal according to claim 2 , wherein the frequency offset is a frequency offset in resource blocks between a first hop and a second hop.
8. The terminal according to claim 2 , further comprising a transmitter that transmits the uplink shared channel in a single slot or a plurality of slots.
9. The terminal according to claim 3 , further comprising a transmitter that transmits the uplink shared channel in a single slot or a plurality of slots.
