FIELD: wireless transmission.
SUBSTANCE: invention relates to wireless transmission. The transmitting device comprises a plurality of generators of modulated user signals. The generator of modulated user signals #k (104_k) (where k=1-n) forms a modulated signal which includes the reference signals for phase noise assessment (PT-RS: a phase tracking reference signal) for a plurality of receiving devices. The wireless unit (109_A, 109_B) transmits the formed modulated signal. The transmission power correction coefficient for reference signals is related to the sequence template used as reference signals on the basis of a one-to-one correspondence.
EFFECT: ensured assessment of phase noise with high accuracy in each of a plurality of receiving devices.
