1. A method for beam failure recovery in a communication network, the method comprising:
receiving a downlink transmission at a user equipment (UE) in an inactive state;
detecting a beam failure based on the downlink transmission at the UE while in the inactive state; and
performing a beam failure recovery (BFR) procedure at the UE in the inactive state based on detecting the beam failure.
