Carrier aggregation configuration method and device

摘要: The present invention provides a carrier aggregation configuration method and device, wherein the is applied to network side, comprises steps of determining information an accessed cell when terminal accesses first frequency band carrier, setting as main cell; set which belongs, cells in all have at least part overlapped coverage second carrier; obtaining measurement for measuring performance each set, ranking according parameters obtain having optimal assistant terminal; sending reconfiguration via radio resource control (RRC) message, accessing by terminal, cell.
