Beam failure recovery method and device, beam failure recovery parameter determination method and device, quasi colocation reference signal determination method and device, and storage medium

An apparatus for beam failure recovery, comprising a processor and a memory for storing execution instructions that when executed by the processor cause the processor to perform steps in following modules:

• a first beam failure recovery module configured to, in response to a non-empty intersection existing among time domain resources corresponding to beam failure recovery processes of N frequency domain bandwidths,
• combine 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.
