Abstract
Methods and devices for beam failure recovery are provided. A method for beam failure recovery includes: when a terminal device in a common beam operation mode detects beam failure in a cell, sending, by the terminal device, a beam failure recovery request message to a network device, wherein the beam failure recovery request message includes indication of a selected candidate beam; and after the beam failure recovery request message is received by the network device and before the terminal device receives indication of a transmission configuration indicator (TCI) state for common beam operation from the network device, performing, by the terminal device, physical downlink control channel (PDCCH) reception and physical downlink shared channel (PDSCH) reception on the cell by using same antenna port quasi co-location (QCL) parameters as the ones associated with the selected candidate beam.
