Abstract
A communication system includes a shared channel occupied by a plurality of user equipments (UEs) and spread with a plurality of channelization codes to transmit user data, and a plurality of control channels for transmitting control information related to the shared channel in order to enable the UEs to receive the shared channel signal. The system generates a plurality of control channel sets by classifying the control channels into a predetermined number of control channels, and assigns the control channel sets so that each of the UEs monitors a particular control channel set among the control channel sets. Upon detecting necessity to modify a control channel set to be assigned to a particular UE among the UEs, a Node B determines to modify a control channel set assigned into the UE to a new control channel set at a predetermined point of time to come. After determining to modify the control channel set, the Node B transmits an indicator indicating expected modification of the control channel set and information on the control channel set to be modified to the UE over a downlink.
