Abstract

The method for transmitting and receiving data at a base station in a wireless communication system according to one embodiment of the present invention includes the steps of: receiving a performance report from a terminal; determining whether the addition of a serving cell is necessary; when the addition of the serving cell is necessary, transmitting a request for receiving a cell identifying signal to one or more other base stations on the basis of the received performance repoπand transmitting a request for transmitting the cell identifying signal to the terminal. According to the embodiment, in a network in which a small cell and a macro cell are overlapped and operated, the terminal can minimize battery consumption and quickly recognize the small cell.

Description

TECHNICAL FIELD

[0001] The present invention relates to a method and apparatus for communicating data using a plurality of carriers in a mobile communication system.BACKGROUND ART

[0002] Mobile communication systems were developed to provide the subscribers with voice communication services on the move. With the rapid advance of technologies, the mobile communication systems have evolved to support high speed data communication services beyond the early voice-oriented services.

[0003] Recently, standardization for a Long Term Evolution (LTE) system, as one of the next-generation mobile communication systems, is underway in the 3rd Generation Partnership Project (3GPP). LTE is a technology for realizing high-speed packet-based communications with the data rate of up to 100 Mbps, which is higher than the currently available data rate, and its standardization is almost complete.

[0004] Recent studies are focused on the LTE-Advanced (LTE-A) for improving data rate with the adaptation of several...
