Abstract: A wireless apparatus according to one aspect of the present invention includes an acquisition unit configured to acquire a communication quality index indicating communication quality of a link for each of a plurality of links forming a multi-link with another wireless apparatus; and a multi-link control unit configured to determine whether to suspend use of a first link having the lowest communication quality among the plurality of links based on comparison between the communication quality index for the first link and a first threshold.

Abstract: A terminal apparatus includes a determination unit and a transmission unit. The determination unit determines a target of transmission power regulation based on a beacon frame. The transmission unit, in a case where it is determined that the target of regulation is not a transmission power density, transmits a first frame in a first frequency band, and in a case where it is determined that the target of regulation is a transmission power density, transmits a second frame which is a duplicate of the first frame in a second frequency band while transmitting the first frame in the first frequency band.

Abstract: A vehicle body rear portion structure includes a rear end panel, a rear side frame, a rear end cross member, a first gusset, and a second gusset. The rear end cross member extends in a vehicle width direction along the rear end panel and is separately disposed above the rear side frame. The first gusset connects the rear side frame to the rear end panel. The second gusset connects the rear side frame to the rear end cross member above the first gusset.

Abstract: An upper side joint section that extends inward in a vehicle width direction from a vicinity of a rear side frame and a lateral side joint section that extends downward from the upper side joint section and that is separated in the vehicle width direction from the rear side frame are provided on a rear floor panel of a vehicle body rear part structure. The rear panel has: a frame joint part to which the rear side frame is joined; a first floor joint part to which the upper side joint section of the rear floor panel is joined; and a second floor joint part to which the lateral side joint section of the rear floor panel is joined. A longitudinal bead is provided on a part of the rear panel between the frame joint part and the second floor joint part. The longitudinal bead extends to a lower end of the rear panel and is opened downward.
