A beam failure recovery method and device and a communication system. The device includes: a receiver configured to, after a period of time upon the terminal equipment receive a beam failure recovery (BFR) response and before activation or reconfiguration signaling, monitor and/or receive a downlink signal in a first cell of the terminal equipment according to an antenna quasi-co-located (QCL) parameter identical to a selected reference signal (q_new) or a reference signal (q_new) indicated by a higher layer.
