Abstract:
1. A method for receiving a downlink signal from a base station (BS) in a multicast broadcast single frequency network (MBSFN) subframe which carries a cell-specific reference signal (CRS) in only a control region, the method performed by a user equipment (UE) and comprising: receiving information indicating an MBSFN subframe configured as an almost blank subframe (ABS) (ABS MBSFN subframe) of which a data region is allocated a reduced transmission power lower than a transmission power in a data region of a normal subframe, among MBSFN subframes; receiving information for matching between a channel through which the CRS is received and a channel through which the downlink signal is received in the data region of the ABS MBSFN subframe; and demodulating the downlink signal using the CRS received in the control region of the ABS MBSFN subframe according to the information indicating the ABS MBSFN subframe.
