1. A terminal comprising:
a receiver that:
receives information regarding a cell among a configured cell group comprising a plurality of cells, a reference signal for a candidate beam configured in the cell identified by the information, and
receives information regarding an index of the reference signal for the candidate beam; and
a processor that, in response to beam failure detection, controls to transmit a recovery request on a configured PUCCH resource, and transmit, using MAC CE, information other than the recovery request,
wherein the information other than the recovery request indicates that there is no reference signal for a candidate beam with received power being greater than or equal to a threshold value configured by higher layer signaling, and
wherein the receiver receives, by higher layer signaling, the information regarding the cell and the information regarding the index of the reference signal for the candidate beam, and a reference signal for a candidate beam corresponding to each cell is always configured in a specific frequency bandwidth.
