Abstract
A reception apparatus according to the present disclosure includes a receiver which, in operation, receives a downlink signal including a first data signal for the reception apparatus and first Reference Signals for Phase Tracking (PT-RS). The first data signal is mapped on a first set of subcarriers and the first PT-RS is mapped to the downlink signal based on a first Modulation and Coding Scheme (MCS) configured for the first data signal. The reception apparatus according also includes a circuit which, in operation, estimates a phase noise using the first PT-RS included in the downlink signal.
Claims12
A reception apparatus comprising:
- a receiver which, in operation, receives a downlink signal including a first data signal and first Reference Signals for Phase Tracking (PT-RS) for the reception apparatus, wherein the first PT-RS is mapped to first resource elements based on a first Modulation and Coding Scheme (MCS) configured for the first data signal;
- and
- a circuit which, in operation, assumes the first PT-RS is present in the first resource elements,
- wherein in a case where Quadrature Phase Shift Keying (QPSK) is used as a modulation scheme of the first MCS, the circuit assumes that the first PT-RS is not present in the downlink signal.
A reception method for a reception apparatus comprising:
- receiving a downlink signal including a first data signal and first Reference Signals for Phase Tracking (PT-RS) for the reception apparatus, wherein the first PT-RS is mapped to first resource elements based on a first Modulation and Coding Scheme (MCS) configured for the first data signal;
- and
- assuming the first PT-RS is present in the first resource elements,
- wherein in a case where Quadrature Phase Shift Keying (QPSK) is used as a modulation scheme of the first MCS, the reception method comprises assuming that the first PT-RS is not present in the downlink signal.
