Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal.
