Claim Text:
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 including a first parameter indicating a physical downlink shared channel (PDSCH) start position and a second parameter indicating a 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) and a second information element indicating physical downlink shared channel (PDSCH) information, the first information element of the DCI indicating transmission antenna ports, a scrambling identity and a number of transmission layers; and using, by the UE, the PDSCH information of the DCI to determine the start position of the PDSCH based on the first parameter of the parameter set and to determine antenna ports being quasi co-located for the PDSCH based on the second parameter of the parameter set.
