1. A method for receiving downlink data in a wireless communication system, comprising:
receiving, by a user equipment (UE), a radio resource control (RRC) message including a parameter set, the parameter set including:
a plurality of first parameters each indicating a corresponding physical downlink shared channel (PDSCH) start position, anda plurality of second parameters each indicating a corresponding channel state information reference signal (CSI-RS) resource; receiving, by the UE, downlink control information (DCI) via a downlink control channel in a subframe, the DCI including:
a first information element associated with a reference signal (RS) to be used for receiving a physical downlink shared channel (PDSCH), anda second information element indicating physical downlink shared channel (PDSCH) information, wherein the first information element of the DCI indicates transmission antenna ports, a scrambling identity and a number of transmission layers, and wherein the PDSCH information of the second information element of the DCI identifies:
one of the plurality of first parameters of the parameter set as the start position of the PDSCH, andone of the plurality of second parameters of the parameter set as the CSI-RS resource; and receiving the reference signal based on the first information element, the PDSCH based on the identified start position, and a CSI-RS via the identified CSI-RS resource. |
