The method for transmitting a control signal for an asymmetric multicarrier in a wireless connection system according to one embodiment of the present invention comprises: determining the size of a carrier indicator field (CIF) indicating a downlink component carrier (DL CC) by which downlink data is transmitted, on the basis of a maximum value of the number of DL CCs and of the number of uplink component carriers (UL CCs) being managed in a base station; transmitting the CIF on a 1st DL CC to a terminal through a physical downlink control channel (PDCCH); and transmitting downlink data on a 2nd DL CC indicated by the CIF to the terminal through a physical downlink shared channel (PDSCH)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting and receiving control signal for merging carriers in transmission","description":"Embodiments of the present invention are directed to a method and apparatus for transmitting and receiving a control signal (for example, PDCCH signal) in an asymmetric multicarrier environment.
