1. A method for transmitting a beam failure recovery request, comprising:
determining, by a terminal device, that a beam failure event has occurred in a first cell, wherein the first cell is served by a first network device; and
transmitting, by the terminal device, a beam failure recovery request (BFRQ) to a second network device in a second cell, wherein the BFRQ is used to indicate that a beam failure event has occurred in the first cell, and the second cell is served by the second network device; wherein
the second cell is different from the first cell;
wherein the transmitting, by the terminal device, the BFRQ to the second network device in the second cell comprises:
transmitting, by the terminal device, the BFRQ to the second network device in the second cell through a first bearer, wherein the first bearer comprises at least one of a physical uplink control channel (PUCCH) or a semi-persistent-physical uplink shared channel (SP-PUSCH);
wherein the transmitting, by the terminal device, the BFRQ to the second network device in the second cell through the first bearer comprises:
transmitting, by the terminal device, the BFRQ to the second network device in the second cell through a target channel according to a second preset rule if the target channel comprises second information, wherein the target channel is the PUCCH or the SP-PUSCH, and the second information is to-be-transmitted information other than the BFRQ; and
the second preset rule is: transmitting the BFRQ based on priorities of the second information and the BFRQ, or multiplexing the second information and the BFRQ for transmission, or prioritizing transmission of the BFRQ.
