A user equipment (UE) may perform measurements on one or more reference signals for one or more beams. In the event that one of the beams has a measurement that indicates a potential beam failure, the UE may increment a beam failure count (BFC) at a physical layer of the UE, and start a BFC timer. In the event that the BFC reaches a threshold value prior to expiration of the BFC timer, the UE may trigger a switch to a different active beam, provide a beam failure indication (BFI) to a higher layer of the UE, or both. A higher layer at the UE may autonomously adjust a BFI threshold for a number of BFIs that are needed to trigger a beam failure declaration to the base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques for beam failure recovery in wireless communications","description":"Methods, systems, and devices for wireless communications are described for detection of beam failure and beam failure recovery.
