FIELD: wireless communication.
SUBSTANCE: method includes obtaining information on a position in a time area of a scheduled first demodulation reference signal (DM-RS) in a slot and transmitting or receiving a PT-RS within a slot, note here that PT-RS position depends on position in time area of planned first DM-RS.
EFFECT: technical result consists in reduction of common phase error caused by phase noise (CPE), and interference between carriers (ICI) caused by loss of orthogonality between subcarriers.
