Abstract
The invention aims to perform UL transmission in an appropriate manner even when using short transmission time intervals (TTIs). A user terminal includes a transmission section that performs the UL transmission using at least one of a plurality of TTIs contained in one subframe of existing systems, and a control section that controls allocation of an UL signal and/or an UL channel. The TTI is constituted of an even number of symbols of the existing system. The control section allocates an uplink control channel on the basis of the TTI.
Claims3
A terminal comprising:
- a receiver that receives a downlink (DL) signal in a first time unit of a plurality of time units included in a subframe;
- a transmitter that transmits acknowledgement/negative acknowledgement (ACK/NACK) information for the DL signal using a physical uplink control channel (PUCCH) in a second time unit of a plurality of time units included in a subframe after a period in units of a subframe;
- and
- a processor that when the second time unit has an even number of symbols, applies frequency hopping to the PUCCH in the second time unit, the frequency hopping being performed between a first half of the second time unit and a second half of the second time unit.
A radio communication method for a terminal, the radio communication method comprising:
- receiving a downlink (DL) signal in a time unit of a plurality of time units included in a subframe;
- transmitting acknowledgement/negative acknowledgement (ACK/NACK) information for the DL signal using a physical uplink control channel (PUCCH) in a second time unit of a plurality of time units included in a subframe after a period in units of a subframe;
- and
- applying frequency hopping to the PUCCH in the second time unit, when the second time unit has an even number of symbols, the frequency hopping being performed between a first half of the second time unit and a second half of the second time unit.
