Abstract (en)
[origin: WO2022080613A1] The present disclosure relates to a method and an apparatus for transmitting or receiving a downlink phase tracking reference signal (PTRS) and/or uplink PTRS in a wireless communication system. According to an aspect of the present invention, the PTRS is received in one or more PTRS subcarrier groups within a specific scheduled bandwidth. Each PTRS subcarrier group includes one or more active PTRS subcarriers to which a PTRS sequence is mapped and one or more null PTRS subcarriers to which the PTRS sequence is not mapped. The one or more null PTRS subcarriers are determined based on at least one of subcarrier spacing (SCS), and modulation and coding scheme (MCS) for DL data as scheduled by a DCI.
