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.
Claims18
A terminal comprising:
- a receiver, which, in operation, receives control information which is used for scheduling of a PUSCH (Physical Uplink Shared Channel) and which includes information for determining a mapping pattern of an uplink DMRS (Demodulation Reference Signal) to resource elements;
- circuitry, which is coupled to the receiver and which, in operation, maps the uplink DMRS to the resource elements based on the information;
- and
- a transmitter, which is coupled to the circuitry and which, in operation, transmits the mapped uplink DMRS,
- wherein the mapping pattern is determined out of a plurality of mapping patterns based on the information, and the plurality of mapping patterns include at least two mapping patterns in which numbers of symbols, to which the uplink DMRS is mapped, are different.
A communication method comprising:
- receiving control information which is used for scheduling of a PUSCH (Physical Uplink Shared Channel) and which includes information for determining a mapping of an uplink DMRS (Demodulation Reference Signal) to resource elements;
- mapping the uplink DMRS to the resource elements based on the information;
- and
- transmitting the mapped uplink DMRS,
- wherein the mapping pattern is determined out of a plurality of mapping patterns based on the information, and the plurality of mapping patterns include at least two mapping patterns in which numbers of symbols, to which the uplink DMRS is mapped, are different.
