A wireless device may detect beam failure of a number of cells. In response to the number of the cells being greater than a maximum number that a beam failure recovery medium-access control control element (BFR MAC CE) accommodates, the wireless device may select one or more cells of the cells based on an ascending order of cell indexes of the cells. The wireless device may transmit the BFR MAC CE comprising a candidate reference signal index or a reserved bit for each of the one or more cells.
