Abstract

Provided is a user terminal to be used in a future wireless communication system which bundles a plurality of slots (sub-frames) in a time direction. When applying bundling, a Front-loaded DMRS (Demodulation Reference Signal) is mapped to the rear of a control channel in a leading slot, and in second and subsequent slots, mapping is carried out on the basis of a rule to prevent conflict between the Front-loaded DMRS and the control channel. A control unit () of a user terminal () stipulates, in second and subsequent slots, the mapping configuration of the Front-loaded DMRS (the existence of mapping and/or the mapping position) on the basis of the aforementioned rules.
