Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/235456
Kind Code:
A1
Abstract:
This user terminal comprises: a control unit which determines, as a spatial relation, one of a transmission control instruction (TCI) state or quasi-co-location (QCL) assumption for downlink transmission, and the specified spatial relation information. The determination is made on the basis of at least one of a comparison of a time offset between uplink transmission and the timing with regard to the spatial relation of uplink transmission with a threshold value, and that the application of the sounding reference signal (SRS) resource set for the uplink transmission is a specific application. The user terminal also comprises a transmission unit which performs uplink transmission using the spatial relation.
