The present invention relates to a method and an apparatus for transmitting a reference signal by a base station in a wireless communication system. The base station generates a channel state information (CSI) reference signal (RS) for each of a plurality of layers, performs mapping the plurality of CSI-RSs to a resource element set constituted by a plurality of resource elements(REs) in a subframe and transmits the subframe with the plurality of mapped CSI-RSs. The plurality of resource elements constituting the resource element set are resource elements that are arranged with constant subcarrier spacing in two neighboring orthogonal frequency division multiplexing (OFDM) symbols, and the subframe has an extended cyclic prefix (CP) structure including 12 OFDM symbols.

The present invention relates to a method and apparatus for transmitting/receiving data in a wireless communication system. According to one aspect of the present invention, a data receiving method is provided wherein a mobile station in a wireless communication system uses a frame including a first subframe in which a physical downlink shared channel (hereinafter, referred to as “PDSCH”) includes a first cyclic prefix (hereinafter, referred to as “CP”) and a second subframe in which the PDSCH includes a second CP, wherein the data receiving method comprises a step in which the mobile station receives information on the length of the first CP from a base station, receives data from the base station through the first subframe, and removes the CP of the data using the information on the length of the first CP. The first CP and the second CP have different lengths.

Disclosed are a method and a device for performing HARQ in a multiple antenna system. A terminal transmits uplink data via a plurality of antennas and through a Physical Uplink Shared Channel (PUSCH), and receives an ACK/NACK (Acknowledgement/Non-Acknowledgement) signal indicating whether or not the uplink data has been received, the signal being received via the plurality of antennas and through a PHICH (Physical Hybrid-ARQ Indicator Channel) which corresponds to the PUSCH. A downlink resource to which the PHICH is mapped is determined on the basis of the index (IPRB—RAlowest—index) of the smallest Physical Resource Block (PRB) among the PRBs to which the PUSCH is mapped, uplink DMRS (Demodulation Reference Signal) cyclic shift parameters (nDMRS) and Orthogonal Code Cover (OCC) index.
