US 2016/0112994 A1 · TERMINAL, BASE STATION, METHOD OF GENERATING DMRS, AND TRANSMISSION METHOD

Abstract

The present invention aims at allowing a demodulation reference signal (DMRS) pattern suitable for a terminal to be selected from among a plurality of DMRS patterns including Legacy DMRS and Reduced DMRS. Disclosed is a terminal including: reception section (21) that receives uplink control information; control section (23) that determines a specific mapping pattern from among a plurality of mapping patterns for an uplink DMRS on the basis of the control information; and DMRS generating section (24) that generates a DMRS according to the specific mapping pattern.
