Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2024/028941
Kind Code:
A1
Abstract:
A terminal according to one embodiment of the present disclosure has a reception unit that receives an instruction to transmit a physical uplink shared channel (PUSCH) that uses more than four layers, and a control unit that determines a transmission power ratio between a phase tracking reference signal (PTRS) and the PUSCH. According to the one aspect of the present disclosure, UL transmission using more than four antenna ports can be appropriately controlled.
