1. A wireless communication method, comprising:
after sending a beam failure recovery request of a secondary cell to a network device, detecting, by a terminal device, first downlink information on the secondary cell;
according to whether the first downlink information is successfully detected, determining, by the terminal device, whether a beam failure recovery of the secondary cell is successful;
in a case that a beam failure occurs in a master cell and the secondary cell at the same time, initiating, by the terminal device, a random access on the master cell, wherein a random access preamble in MSG 1 indicates to the network device a downlink beam index of the master cell, and MSG 3 carries an MAC control element (MAC CE) indicating a downlink beam index of the secondary cell.
