| titleOfInvention | Method for pilot symbol transmission in downlink MIMO system |
| abstract | The present invention relates to a method for transmitting a pilot signal in a downlink MIMO (Multi Input Multi Output) system that supports a first UE (User Equipment) supporting N number of transmission antennae out of a total of M transmission antennae and supports a second UE supporting said M (M > N) number of transmission antennae. Said method comprises a step wherein a pilot symbol is placed as an image in the resource block (RB) region on a subframe that enables the transmission of a user-specific pilot symbol to said second UE in a base station; and a step wherein the subframe whereon said pilot symbol has been placed as an image is transmitted, wherein said RB region includes a first region and a second region, and the first region and second region each include a certain number of continuous OFDM symbols on a respective time axis, and on said first region is placed as an image a cell-specific pilot symbol with respect to the transmission antenna ports 0 to N-1 that can recognize both said first UE and said second UE, and on said second region is placed as an image a user-specific pilot symbol with respect to the transmission antenna ports 0 to M that can recognize said UE only. |
