Methods and apparatuses for receiving or transmitting downlink signal in MBSFN subframe

A method for transmitting a downlink signal to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) subframe, the method performed by a base station (BS) and comprising:

• transmitting, to the UE, information indicating:
• an MBSFN subframe of which a data region is allocated for a cell-specific reference signal (CRS), among plural MBSFN subframes, and
• a frequency resource region in which the indicated MBSFN subframe is configured for the UE;
• wherein the information indicates that the UE is to demodulate the downlink signal received in the data region of the indicated MBSFN subframe, based on the CRS received in a part of the data region of the indicated MBSFN subframe and a UE-specific reference signal received in a remaining part of the data region of the indicated MBSFN subframe.

A user equipment (UE) for receiving a downlink signal from a base station (BS) in a multicast broadcast single frequency network (MBSFN) subframe, comprising:

• a radio frequency (RF) unit for transmitting or receiving an RF signal;
• and
• a processor for controlling the RF unit,
• wherein the processor
• receives, through the RF unit, information indicating:
• an MBSFN subframe, of which a data region is allocated for a cell-specific reference signal (CRS), among plural MBSFN subframes, and
• a frequency resource region in which the indicated MBSFN subframe is configured for the UE, and
• demodulates the downlink signal received in the data region of the indicated MBSFN subframe based on the CRS received in a part of the data region of the indicated MBSFN subframe and a UE-specific reference signal received in a remaining part of the data region of the indicated MBSFN subframe, according to the received information.
