Aspects described herein relate to beam failure detection (BFD) for mixed control and/or control resource sets (CORESETs). In an example, the aspects may include identifying one or more groups of CORESETs, each of the one or more groups of CORESETs include at least one half-duplex (HD) CORESET, full-duplex (FD) CORESET, or combination thereof; receiving one or more of the at least one HD CORESET and FD CORESET of the one or more groups of CORESETs from a network entity; performing a BFD measurement procedure with a reference signal associated with at least one CORESET of the one or more groups of CORESETs; and detecting whether a cell level failure event or a group level failure event is triggered based on the BFD measurement procedure.
