Abstract

Disclosed is a method for a terminal transmitting interference information and a base station controlling inter-cell interference in a wireless communication system supporting carrier aggregation (CA). The method for the terminal transmitting interference information in the wireless communication supporting CA comprises the following steps: receiving a downlink reference signal from a serving base station; measuring noise which is not a signal from the serving base station and the amount of downlink interference from at least one nearby base station, excluding the serving base station, per each component carrier (CC) comprising the terminal using the downlink reference signal that is received by the serving base station; and generating interference information based on the result of the measurement, wherein the interference information can be generated for each CC.
