Abstract: 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. 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.

Abstract: Default QCL assumptions for UEs and base stations to apply after identifying a new beam in response to beam failure detection are provided for single-DCI multi-TRP communication. In one aspect, a default QCL assumption for PDSCH after beam failure detection may be applied based on TCI states corresponding to a lowest codepoint among the TCI codepoints containing two different states. In another aspect, a default QCL assumption for PDSCH after beam failure detection may be applied based on at least one of: a lowest CORESET-ID in a latest monitored slot, a selected RS index during beam failure recovery, CORESET-0, or a first TCI state corresponding to the lowest TCI codepoint indicating two TCI states. Additionally, default QCL assumptions for UEs and base stations to apply during beam failure recovery are provided for single-DCI multi-TRP communication when the UE is not configured with a set of beam failure detection resources.
