<p>The present invention relates to a control of an extension bearer in a heterogeneous network wireless communication system. A macro base station according to the present invention generates an RLC extension request message for requesting an establishment of an RLC end-based extension bearer in a small cell based on the measurement report received from a terminal, transmits the RLC extension request message to a small base station, and receives, from the small base station, an RLC extension response message regarding whether the extension bearer is established or not in the small cell as a response to the RLC extension request message. The macro base station may forward data to be transmitted, by the terminal, to the small base station, and the small base station may transmit the data to the terminal by means of the extension bearer. According to the present invention, the macro base station may disperse excessive loads or loads that require specific QoS to the small cell, and the terminal may smoothly receive a data service.</p> |
