Abstract: An apparatus is disclosed including a receiver that receives a downlink control information and a downlink shared channel that is scheduled by the downlink control information; a processor that determines an allocation of the downlink shared channel in a time domain based on a first timing indicated by a first time unit and a second timing indicated by a second time unit that are obtained from information notified by the downlink control information; and an output apparatus that outputs information based on the downlink shared channel, wherein the first timing is defined based on a numerology of the downlink shared channel. In other aspects, a system is also disclosed.

Abstract: A terminal is disclosed that includes a receiver that receives downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH). The terminal also includes a processor that, when the DCI is cyclic redundancy check (CRC) scrambled by a radio network temporary identifier used to choose a modulation and coding scheme (MCS) table (MCS-RNTI), determines, based on the MCS-RNTI, a downlink phase tracking reference signal (PT-RS) position for the PDSCH. In other aspects, a radio communication method, a base station, and a system are also disclosed.
