Apparatus for transmitting and receiving data in a wireless communication system and method thereof

A user equipment for receiving data in wireless communication system, the method comprising:

• a receiving module configured to receive a physical downlink control channel (PDCCH) carrying downlink control information format 1A in a subframe and receive a physical downlink shared channel (PDSCH) corresponding to the PDCCH in the subframe;
• and
• a processor configured to process a signal received from the receiving module, wherein:
• the PDSCH is received using a single antenna transmission scheme or transmission diversity scheme, which is based on a cell specific reference signal (CRS), when the subframe is a non-multimedia broadcast multicast service single frequency network (non-MBSFN) subframe,
• the PDSCH is received using a single layer transmission scheme, which is based on a user equipment specific reference signal, when the subframe is a MBSFN subframe.

A method of transmitting, by a base station, data in wireless communication system, the method comprising

• transmitting a physical downlink control channel (PDCCH) carrying downlink control information format 1A to a user equipment in a subframe;
• and
• transmitting a physical downlink shared channel (PDSCH) corresponding to the PDCCH to the user equipment in the subframe, wherein:
• the PDSCH is transmitted using a single antenna transmission scheme or transmission diversity scheme, which is based on a cell specific reference signal (CRS), when the subframe is a non-multimedia broadcast multicast service single frequency network (non-MBSFN) subframe,
• the PDSCH is transmitted using a single layer transmission scheme, which is based on a user equipment specific reference signal, when the subframe is a MBSFN subframe.
