1. A user equipment, comprising one or more processors communicatively coupled to memory, the one or more processors configured to cause the user equipment to:
receive an uplink transmission transmitted by the user equipment;
generate a beam failure indication based on a determination that a beam failure associated with full-duplex communication has occurred as a result of interference from the uplink transmission; and
transmit the beam failure indication to a network entity via (1) an uplink channel of an uplink beam in response to the user equipment being able to communicate with the network entity via the uplink beam or (2) a random access channel (RACH) message in response to the user equipment not being able to communicate with the network entity via the uplink beam or in response to the beam failure being due to downlink quality degradation,
wherein the user equipment further comprises a first antenna panel and a second antenna panel, wherein:
the one or more processors are further configured to cause the user equipment to use the first antenna panel to transmit the uplink beam;
the one or more processors are further configured to cause the user equipment to use the second antenna panel to receive a downlink beam; and
the interference from the uplink transmission comprises self-interference by the user equipment measured via the second antenna panel from an interference measurement resource (IMR) configured in a radio resource control (RRC) radio link monitoring reference signal (RLM-RS) configuration for beam failure detection.
