METHOD AND APPARATUS FOR TRANSMITTING A REFERENCE SIGNAL IN A MULTl-ANTENNA SYSTEM |
| 摘要 |
A method is provided for transmitting, by a user equipment (UE), a demodulation reference signal (DMRS) in a wireless communication system. A first DMRS sequence, which is associated with a first layer, and a second DMRS sequence, which is associated with a second layer, are transmitted to a base station. A first orthogonal cover code (OCC) is applied to the first and second DMRS sequences. A third DMRS sequence, which is associated with a third layer, and a fourth DMRS sequence, which is associated with a fourth layer, are transmitted to the base station. A second OCC is applied to the third and fourth DMRS sequences. |

1. A method for transmitting, by a user equipment (UE), a demodulation reference signal (DMRS) in a wireless communication system, the method comprising:
transmitting a first DMRS sequence, which is associated with a first layer, and a second DMRS sequence, which is associated with a second layer, to a base station, wherein a first orthogonal cover code (OCC) is applied to the first and second DMRS sequences; and transmitting a third DMRS sequence, which is associated with a third layer, and a fourth DMRS sequence, which is associated with a fourth layer, to the base station, wherein a second OCC is applied to the third and fourth DMRS sequences. |
