Abstract:
A method for receiving downlink data in a wireless communication system is provided. A user equipment receives downlink control information via a downlink control channel in a subframe. The downlink control information includes reference signal (RS) information and physical downlink shared channel (PDSCH) information. The RS information indicates transmission antenna ports, a scrambling identity and a number of transmission layers. The user equipment receives a RS for demodulating a PDSCH based on the RS information in the subframe. The RS is generated based on the scrambling identity. The user equipment receives downlink data via the PDSCH in the subframe. Resource element (RE) mapping information on REs assigned for the PDSCH is determined based on the PDSCH information.
