As to a method aspect of the technique performed by the radio device (100), a control message is received from the RAN (600). The control message is indicative of a spatial relation between a first physical channel (602) and a second physical channel (608). A transmission or a transmission attempt to the radio access node (200) is monitored on the second physical channel (608). The transmission or transmission attempt uses a filter (604) in the spatial domain (506), which is used or configured for a transmission (302) to the radio access node (200) or a reception (302) from the radio access node (200) on the first physical channel (602) according to the spatial relation. The BFD is performed based on a result of the monitoring."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Technique for beam failure detection","description":"A technique for performing beam failure detection, BFD, of a radio beam between a radio device (100) and a radio access node (200) in a radio access network, RAN (600), is described.
