Title:
USER EQUIPMENT AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/053977
Kind Code:
A1
Abstract:
User equipment according to one aspect of the present invention is characterized by having: a reception unit that receives trigger information triggering a beam measurement of an aperiodic channel state information reference signal (A-CSI-RS); and a control unit that controls the beam measurement of the A-CSI-RS on the basis of whether or not a transmission configuration indication (TCI) state of the A-CSI-RS is activated. Due to this aspect of the present invention, a beam report can be reported with low latency.
