18. A wireless communication device comprising:
at least one processor configured to:
receive, via a receiver in an active transmission configuration indicator (TCI) switching procedure, a physical data shared channel with an activation command;
determine that a target TCI state is absent from an active TCI state list of the physical data shared channel;
determine whether the target TCI state is known; and
set, in accordance with a determination of whether the target TCI state is known, a first counter to count a number of listen-before-talk (LBT) failures in a synchronization signal block (SSB) period.
