During acquisition, the command may comprise a SIB. During a connected mode of operation, the command may comprise a TPC message, assistance information, an RRC message, or a DCI message. ## Claims ### Claim 1 A method of clutter mitigation for a base station, comprising: scanning through a plurality of antenna beams from the base station to identify an affected antenna beam that is subjected to a clutter-induced interference;
