Title:
METHOD FOR PTRS RECEPTION FOR PHASE NOISE CANCELLATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/182242
Kind Code:
A2
Abstract:
A method for operation of a terminal in a wireless communication system according to an embodiment of the present specification may comprise the steps of: receiving modulation and coding scheme (MCS) information for each of two or more codewords from a base station; on the basis of the MCS information, determining a demodulation reference signal (DMRS) antenna port to which a phase tracking reference signal (PTRS) antenna port has been mapped; and receiving a PTRS on the basis of the DMRS antenna port, wherein the DMRS antenna port is determined to be a DMRS antenna port having a lowest index from among one or more DMRS antenna ports included in a codeword having a highest MCS from among the two or more codewords.
