Abstract: A user equipment (UE) performs radio communication with a base station that manages a cell including N (N≥2) transmission/reception points. The UE comprises: a communicator configured to receive a radio resource control (RRC) message from the base station, the RRC message including information for configuring N beam failure detection resource sets; and a controller configured to individually detect beam failure for each of the N beam failure detection resource sets. The controller is configured to determine, in a case where there is a beam failure detection resource set that does not provide a reference signal resource for detecting the beam failure, the reference signal resource based on a control resource set (CORESET) pool index associated with the beam failure detection resource set.

Abstract: An object detection device includes: a transceiver having a predetermined resonance frequency; a driving signal generation unit generating a driving signal having a driving frequency different from the resonance frequency for driving the transceiver; a filter extracting and outputting at least one received signal from received signals of the transceiver; and a detection determination unit performing object detection determination based on the extracted at least one received signal. The received signals include a first and second received signals, the first received signal having a frequency that has been shifted from the driving frequency to the resonance frequency; and the filter has a characteristic that: when extracting the first received signal, outputs the extracted first received signal as a first output signal, and when extracting the second received signal, outputs the extracted second received signal as a second output signal, the first output signal being greater than the second output signal.

Abstract: An object detection device that detects a corner of an object includes: a transmitter that transmits a search wave; receivers that receive a reflected wave reflected off the corner. The device determines a first path length of the search wave from the transmitter to a first receiver, and uses the positions of the transmitter and the first receiver as focal points to find a first ellipse whose distances from the transmitter and the first receiver add up to the first path length. The device determines a second path length of the search wave from the transmitter to a second receiver, and uses the positions of the transmitter and the second receiver as focal points to find a second ellipse whose distances from the transmitter and the second receiver add up to the second path length. The device finds an intersection point between the first and second ellipses as the corner.
