7. 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
estimating a phase noise using the first PT-RS,
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.
