Abstract:
Even in the case of transmitting the uplink data and the demodulation reference signal using the short TTI, in order to appropriately control the UL transmission, according to one aspect of the present invention, a user terminal transmits a UL signal and a reference signal by using a predetermined sTTI among multiple sTTIs included in a slot, and controls the allocation of the UL signal and the reference signal based on a predetermined allocation pattern among multiple allocation patterns showing allocations of UL signals and reference signals. In these multiple allocation patterns, a UL signal and a reference signal are included in the same slot, and the reference signal is allocated to the same sTTI where the UL signal is allocated, or to an sTTI preceding the sTTI the UL signal is allocated.
