FIELD: electrical communication engineering.
SUBSTANCE: invention relates to means of providing operation of user equipment in a wireless communication system. Method may include receiving modulation and coding (MCS) information for each of two or more codewords from base station (BS); determining an antenna port of a demodulation reference signal (DMRS), to which the phase tracking reference signal (PTRS) antenna port is displayed, based on the MCS information and the PTRS reception based on the DMRS antenna port, wherein the DMRS antenna port with the lowest index among one or more DMRS antenna ports included in the code word with the highest MCS of the two or more codewords can be determined as the DMRS antenna port.
EFFECT: technical result consists in possibility of suppressing phase noise.
