摘要： Provided is a user terminal which is used in a future wireless communication system which bundles a plurality of slots (sub-frames) in the time direction. When applying bundling, in the leading slot, Additional DMRS (Demodulation Reference Signal) is mapped according to channel quality (factors which lead to a deterioration in quality, such as Doppler shift, propagation environment, etc.), and in second and subsequent slots, the existence of Additional DMRS mapping or the mapping position is selected on the basis of rules concerning Additional DMRS mapping. The control unit (203) of the user terminal (20) specifies, in second and subsequent slots, the existence of Additional DMRS mapping and the mapping position on the basis of the aforementioned rules.
