1. An apparatus configured to be employed in a UE (User Equipment), comprising:
a memory interface; and
processing circuitry configured to:
processing a Downlink Control Information (DCI) message that comprises one or more beam indication fields, wherein each beam indication field of the one or more beam indication fields comprises an associated beam index that indicates, for an associated channel, an associated beam of an associated Beam Pair Link (BPL), wherein the associated channel for each beam indication field of the one or more beam indication fields is one of a data channel or a first control Search Space (SS); and
send, for each beam indication field of the one or more beam indication fields, the associated beam index to a memory via the memory interface.
