Abstract
A beam failure recovery request transmission method, reception method, devices, and systems relating to a communication technology field are provided to solve a problem that UE cannot transmit a beam failure recovery request to a base station when UE detects failure of only parts of PDCCH beams, resulting that beam failure cannot be recovered in time. The transmission method performed by UE includes: detecting whether each of all PDCCH beams fails, the all PDCCH beams being configured by base station for UE to monitor; if UE determines that the quantity of failed PDCCH beams is within a preset range greater than 0 and less than a total quantity of all PDCCH beams, transmitting a first beam failure recovery request to base station; if UE determines failure of all PDCCH beams, transmitting a second beam failure recovery request different from the first beam failure recovery request to base station.
