In the method, a first carrier is set up, and a second carrier is added in addition to the first carrier. In addition, the first carrier is a time division duplex (TDD) carrier for which an uplink subframe and a downlink subframe are positioned at different times in a frame, and the second carrier is a carrier only for a downlink that consists of downlink subframes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for aggregating carriers in wireless communication systems","description":"The present invention relates to a method and apparatus for aggregating carriers in wireless communication systems.
