Beam Failure Recovery Using Unified TCI and CORESET RS Sets

The patent applies local quality by differentiating between CORESETs that follow unified TCI state and those that do not. Specifically, the patent introduces separate determination rules for BFD-RS sets based on whether the associated CORESET applies unified TCI state or uses traditional TCI state indication. This allows the system to maintain adaptability for multi-beam management while resolving ambiguity by applying different quality rules to different CORESET types.

The patent segments the BFD-RS set determination process into two distinct paths: one for CORESETs with unified TCI state application and another for CORESETs without unified TCI state application. This segmentation is achieved by introducing separate identification rules that check the unified TCI state application status of each CORESET, thereby eliminating the ambiguity that would otherwise exist in the unified determination process.

The patent applies preliminary action by pre-establishing a clear determination hierarchy for BFD-RS sets before the actual beam failure detection occurs. The patent defines advance rules that first check unified TCI state application status, then use monitoring periodicity as a secondary criterion, and finally use CORESET ID as a tertiary criterion. This preliminary structuring of determination rules simplifies the complexity that would otherwise arise when handling excessive RS quantities.

The patent changes the determination parameters from a single unified criterion to a multi-level parameter system. The first parameter is unified TCI state application status (binary), the second parameter is monitoring periodicity (continuous), and the third parameter is CORESET ID (discrete). This parameter transformation allows the system to handle exceeded maximum RS counts by systematically prioritizing different parameters in a defined sequence, thereby reducing determination complexity.
