US 2019/0357248 A1 · USER TERMINAL AND RADIO COMMUNICATION METHOD

Abstract

The present invention is designed so that, even when a demodulation reference signal for an uplink data channel is multiplexed in a short TTI, this demodulation reference signal can be transmitted adequately. A user terminal according to one aspect of the present invention has a receiving section that receives information about the number of combs that are supported, and a control section that controls transmission of a demodulation reference signal for an uplink data channel in a second transmission time interval (TTI), which is shorter than a first TTI, and the control section maps the demodulation reference signal to a comb-shaped resource set, and maps the uplink data channel to a frequency resource of a bandwidth associated with the number of combs supported.
