Abstract
The present disclosure 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.
Claims20
A communication apparatus comprising:
- a transmitter, which, in operation, transmits, to a terminal, control information which is used for scheduling of PUSCH (Physical Uplink Shared Channel) and which includes information for determining a mapping of an uplink DMRS (Demodulation Reference Signal) to resource elements;
- a receiver, which, in operation, receives, from the terminal, the uplink DMRS, which is mapped to the resource elements based on the information and which is transmitted multiplexed with the PUSCH;
- and
- circuitry, which, in operation, performs a channel estimation based on the received uplink DMRS.
