An apparatus for determining channel quality indicator (CQI) report cycles for user equipments (UEs), upon receiving CQI information from the UEs receiving a high speed downlink packet access (HSDPA) service from a Node B, in a mobile communication system including the Node B, a plurality of the UEs existing in a cell region occupied by the Node B, a controlling radio network controller (CRNC) connected to the Node B, and a serving radio network controller (SRNC) connected to the CRNC. The Node B determines recommended CQI report cycles based on the number of UEs and the CQI information, and transmits the determined recommended CQI report cycles to the SRNC via the CRNC. The SRNC determines CQI report cycles for the UEs referring to the recommended CQI report cycles, and transmits the determined CQI report cycles to the UEs and the Node B.
