A method for configuring carrier resources and reporting carrier information of a multi-carrier cell includes a radio network controller (RNC) that configures each carrier with a carrier processing module (CPM) ID in Node B, and Node B allocates a CPM for each carrier based on CPM ID received. The RNC configures a CPM ID for each newly added secondary carrier. Node B allocates a CPM for the secondary carrier based on the CPM ID received. The audit response message and the resource state indication message, which Node B sends to the RNC contains one or more resource state information (RSI) elements of the CPM, and each RSI element contains the ID of the CPM corresponding to it. The configuration of the carrier resources and the report of the carrier RSI during the cell setup, cell reconfiguration, resource indication and audit response of the multi-carrier cell system are realized.
