Document Type and Number:
WIPO Patent Application WO/2024/034128
Kind Code:
A1
Abstract:
A terminal according to an aspect of the present disclosure includes: a reception unit that receives downlink control information including a first field that indicates a transmission precoding matrix indicator (TPMI) and a second field that indicates a relationship between a port of an uplink phase tracking reference signal (PTRS) and a port of a demodulation reference signal (DMRS) for an uplink shared channel (PUSCH); and a control unit that determines, on the basis of the downlink control information, the DMRS related to the PTRS shared by three or more PUSCH antenna ports in the TPMI or the DMRS related to the PTRS shared by the PUSCH antenna ports for each of CDM group subsets in the TPMI.
