… RRC configures a certain amount of SSBs as candidate reference signals for a certain TCI
state, eg state 0, and then one uses MAC CE to pick one resource to be the “active” resource (eg
the one to be used as the spatial QCL reference) in that TCI state. Another state can be
configured with candidate P CSI-RS resources and MAC CE selects one of those to be used as
spatial QCL reference for this state. … Assuming X candidate RSs are configured as candidate
spatial QCL references within a TCI state and assuming the corresponding RS IDs can be …
