Title:
COMMUNICATION DEVICE, BASE STATION, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/276896
Kind Code:
A1
Abstract:
UE (100) performs wireless communication with a base station (200) that manages a cell (250) having N (N≥2) TRPs (201#0, 201#1). The UE (100) comprises: a communication unit (110) for receiving from the base station (200) an RRC message including a beam failure detection configuration (520) comprising information for configuring N beam failure detection resource sets and associated with a downlink bandwidth portion which is a part of the bandwidth of the cell (250); and a control unit (120) for detecting, during wireless communication using the downlink bandwidth portion, beam failure with respect to each of the N beam failure detection resource sets (521#0, 521#1) separately.
