1. A method of wireless communication performed by a user equipment (UE), comprising:
selecting a first physical uplink control channel (PUCCH) resource, of a plurality of resources, for a first transmission of a request to initiate a beam failure recovery procedure;
determining that a second transmission is scheduled to be transmitted using the first PUCCH resource contemporaneously with the first transmission of the request to initiate the beam failure recovery procedure,
wherein the second transmission is a hybrid automatic repeat request acknowledgement message with a PUCCH format 1 that is to be prioritized for the first PUCCH resource over the first transmission of the request to initiate the beam failure recovery procedure;
selecting a second PUCCH resource for the first transmission of the request to initiate the beam failure recovery procedure based at least in part on the second transmission being scheduled to be transmitted using the first PUCCH resource contemporaneously with the first transmission of the request to initiate the beam failure recovery procedure and based at least in part on the hybrid automatic repeat request acknowledgement message with the PUCCH format 1 being prioritized for the first PUCCH resource over the first transmission of the request to initiate the beam failure recovery procedure;
determining that the first transmission of the request to initiate the beam failure recovery procedure on the second PUCCH resource is to be dropped;
selecting a scheduling request (SR) resource based at least in part on the determination that the first transmission of the request to initiate the beam failure recovery procedure on the second PUCCH resource is to be dropped; and
transmitting a request for an uplink grant on the SR resource to enable initiation of a beam failure recovery resource.
