APPARATUS AND METHOD FOR SUPPORTING MOBILITY MANAGEMENT IN COMMUNICATION SYSTEMS WITH LARGE NUMBER OF ANTENNAS

摘要

PURPOSE: A device for supporting mobility management and a method thereof are provided to satisfy the demands for wireless data traffic which is remarkably increased. CONSTITUTION: A base station transmits one or more first control beams including a reference signal in order to enable a mobile station to measure data. The base station receives a first measurement report for one or more first control beams from the mobile station(1205). The base station selects one of the first control beams for one or more control channels assigned to the mobile station based on the first measurement report. The base station transmits control information through one or more control channel to the mobile station using the selected one or more control beams(1209). [Reference numerals] (1201) Measurement/report configuration; (1203) Determine measurement and transmission/reception beam pairs; (1205) Report measurement; (1207) Transmit the same control information using all control beams in a cell; (1209) Control information; (1211) Receive and combine the control information from a plurality of beams; (AA) Mobile station(connected state); (BB) Base station
