Disclosed is a transmission apparatus which enables high transmission-rate communication by mapping DMRSs in a way adapted to the reception environment of each terminal. The transmission apparatus includes: reference signal configuration section (101) that configures a DMRS mapping pattern for each terminal and outputs a DMRS and information indicating the DMRS mapping pattern; and transmission section (106) that transmits a transmission signal including the information indicating the DMRS mapping pattern configured by reference signal configuration section (101) and the DMRS mapped according to the DMRS mapping pattern to the terminal.
