1. A method for implementing multiple active-coordination-set (ACS) aggregation by a first master base station of a first active-coordination-set (ACS) for mobility management of a user equipment (UE), the method comprising the first master base station:
coordinating aggregation of control-plane and user-plane communications with the UE between at least the first ACS and a second ACS by communicating with a second master base station of the second ACS, the first ACS including the first master base station and at least a second base station, the second ACS including the second master base station and at least a third base station;
communicating, jointly with at least one other base station in the first ACS, with the UE using at least one of a first coordinated multipoint joint transmission or a first coordinated multipoint joint reception between a plurality of base stations in the first ACS and the UE, the at least one of the first coordinated multipoint joint transmission or the first coordinated multipoint joint reception associated with the control-plane and user-plane communications;
receiving, from the second master base station of the second ACS, control-plane information or user-plane data that is associated with at least one of a second coordinated multipoint joint transmission or second coordinated multipoint joint reception between a plurality of base stations in the second ACS and the UE; and
aggregating the control-plane and user-plane communications communicated by the first ACS with at least a portion of the control-plane information or the user-plane data from the second master base station to coordinate data throughput to the UE.
