1. A method for beam failure recovery, comprising:
obtaining, by a terminal, N pieces of configuration information, wherein the N pieces of configuration information are applicable to different transmission and reception points (TRPs), the configuration information comprises a parameter for beam failure recovery, and N is an integer greater than 1; and
in a case that a beam failure event occurring on at least one TRP is determined, transmitting, by the terminal, a beam failure recovery request based on the configuration information;
wherein in a case that a beam failure event occurs on M TRPs, and first resources, used for transmitting a beam failure recovery request by the terminal, in configuration information of the M TRPs are the same, wherein M is an integer greater than 1,
the transmitting a beam failure recovery request based on the configuration information comprises:
transmitting a beam failure recovery request to a higher-priority TRP in the M TRPs with the beam failure event by using the first resource in the configuration information of the M TRPS;
wherein a priority of the TRP is determined based on spatial relation information.
