Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/230863
Kind Code:
A1
Abstract:
This user terminal comprises: a control unit which, if a first reference signal for a spatial relationship of an uplink shared channel is not indicated, determines, in a single slot for transmission of the uplink shared channel and a latest transmission using a sounding reference signal (SRS) resource indicated by downlink control information scheduling the uplink shared channel, a second reference signal based on a transmission control instruction (TCI) state or a quasi co-location (QCL) assumption, and which uses the second reference signal for the first reference signal; and a transmit unit which transmits the uplink shared channel on the basis of the first reference signal.
