Title:
TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/255424
Kind Code:
A1
Abstract:
A terminal (200) sets a PCell and an SCell at the same time. The terminal (200) comprises, in the SCell, a reception unit (220) for receiving a reference signal that is used for detecting a beam failure, and a control unit (270) for performing a beam failure recovery procedure on the basis of the reception quality of the reference signal. The SCell belongs to a prescribed group concerned with a BFR procedure. The control unit (270) performs the BFR procedure in a prescribed cell within a prescribed group.
