PROBLEM TO BE SOLVED: To appropriately perform CA (Carrier Aggregation) using an FDD (Frequency Division Duplex) system carrier and a TDD (Time division Duplex) system carrier.SOLUTION: When a radio base station eNB performs CA using an FDD system carrier f1 and a TDD system carrier f10, the radio base station eNB sets the FDD system carrier f1 as a PCC (Primary Component Carrier), and the TDD system carrier f10 as a SCC (Secondary Component Carrier). |
