Abstract: A method is provided for radio link failure (RLF) detection, link failure recovery, beam failure recovery (BFR) and radio link monitoring (RLM), and for interactions between modules for RLF, BFR, RLM and, integration and unification of indications. A device may measure a reference signal received over one or more communication paths of a radio link to generate reference signal measurements, and select, from the one or more communications paths, at least one path for link quality assessment of a radio link operation based on the reference signal measurements and a configured criterion. The device may generate a radio link indication based on an assessed link quality metric or a link recovery operation status associated with the selected at least one path, and send the radio link indication from a physical layer of the device to a upper layer of the device.
