1. A method for beam failure recovery, comprising: in response to a non-empty intersection existing between time domain resources corresponding to beam failure recovery processes of N frequency domain bandwidths,
combining the beam failure recovery processes of the N frequency domain bandwidths into a single beam failure recovery process and performing the single beam failure recovery process;
wherein N is an integer greater than 1 and a time domain resource corresponding to a beam failure recovery process of a frequency domain bandwidth of the N frequency domain bandwidths comprises a period from detecting a beam failure event to monitoring beam failure response information;
wherein combining the beam failure recovery processes of the N frequency domain bandwidths into the single beam failure recovery process and performing the single beam failure recovery process comprises: in response to requiring transmission of first information corresponding to one frequency domain bandwidth, determining a first frequency domain bandwidth set, and transmitting first information corresponding to the first frequency domain bandwidth set;
wherein a beam failure event occurs and has not been recovered successfully for each frequency domain bandwidth in the first frequency domain bandwidth set;
wherein the first information corresponding to the first frequency domain bandwidth set comprises first information corresponding to each frequency domain bandwidth in the first frequency domain bandwidth set; and
wherein the first information corresponding to the each frequency domain bandwidth in the first frequency domain bandwidth set comprises an index of a component carrier (CC) or an index of a CC and indication information of a new reference signal selected from a candidate reference signal set corresponding to the each frequency domain bandwidth.
