Abstract

A method for receiving a downlink signal from a base station (BS) in a multicast broadcast single frequency network (MBSFN) subframe is disclosed. The method is performed by a user equipment (UE) and includes receiving information indicating an MBSFN subframe configured as an almost blank subframe (ABS) (ABS MBSFN subframe) among MBSFN subframes of which a data region is allocated a reduced transmission power lower than a transmission power in a data region of a normal subframe, and demodulating the downlink signal received in the data region of the ABS MBSFN subframe based on a cell-specific reference signal (CRS) in a control region of the ABS MBSFN subframe according to the information.
