Title: USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Abstract:
The present invention suitably transmits demodulation reference signals, even when the demodulation reference signals for an uplink data channel are multiplexed in a short Transmission Time Interval (TTI). A user terminal according to an aspect of the present invention is characterized by including: a receiving unit which receives information on the number of supported combs; and a control unit which controls the transmission of demodulation reference signals for an uplink data channel in a second TTI shorter than a first TTI, wherein the control unit maps the demodulation reference signals to a resource set having a comb shape, and maps the uplink data channel to a frequency resource having a bandwidth associated with the number of supported combs.
