Abstract: A beam failure processing method includes determining a beam failure of a first cell. A beam failure recovery procedure of a primary cell in the first cell and a second cell is performed before beam failure recovery of the first cell succeeds and if a beam failure of the second cell is determined. The first cell is the primary cell and the second cell is a secondary cell, or the first cell is the secondary cell and the second cell is the primary cell. The method also includes sending information to a network device. The information is used to indicate at least a beam failure of the primary cell in the first cell and the second cell.
