METHOD AND APPARATUS FOR TRANSMITTING A REFERENCE SIGNAL IN A MULTI-ANTENNA SYSTEM
摘要
Provided are a method and apparatus for transmitting a reference signal in a multi-antenna system. A terminal generates a plurality of reference signal sequences in which cyclic shift values that are different from each other are allocated to the respective plurality of layers, and generates an orthogonal frequency division multiplexing (SC-FDMA) symbol to which the plurality of reference signal sequences are mapped. The SC-FDMA symbol is transmitted to a base station via a plurality of antennas. Each of the reference signal sequences is multiplied by either +1 or -1 in accordance with an orthogonal covering code (OCC) index corresponding to the cyclic shift field in a DCI format transmitted via a physical downlink control channel (PDCCH) for each layer.
