Abstract
Provided are a wireless communication method and a terminal device, wherein same can determine whether a beam failure recovery is successful. The method comprises: after a beam failure recovery request of a secondary cell is sent to a network device, a terminal device detecting first downlink information on the secondary cell; and the terminal device determining, according to whether the first downlink information is successfully detected, whether the beam failure recovery of the secondary cell is successful.
Claims18
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.
A terminal device, comprising:
- a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to:
- after sending a beam failure recovery request of a secondary cell to a network device, detect first downlink information on the secondary cell;
- determine whether a beam failure recovery of the secondary cell is successful according to whether the first downlink information is successfully detected;
- in a case that a beam failure occurs in a master cell and the secondary cell at the same time, initiate 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.
