METHOD AND APPARATUS FOR LINK ADAPTATION IN PRECODED MIMO SYSTEMS |
| 摘要 |
Embodiments of the invention relate to methods and apparatus for link adaptation in a preceded MIMO system. According to one embodiment, there is provided a method for link adaptation in a precoded MIMO system. The method comprises: receiving first channel quality information γCQI; with respect to at least one layer r in a plurality of layers in a link; obtaining a Hybrid Automatic Repeat Request (HARQ) scaling factor μr that is associated with a HARQ feedback; and interpreting the first channel quality information γCQI into second channel quality information {circumflex over (γ)}r based on at least the HARQ scaling factor μr, wherein the second channel quality information {circumflex over (γ)}r is for adapting the at least one layer r in the plurality of layers. According to another embodiment, there is provided an apparatus for link adaptation in a precoded MIMO system. |

1. A method for link adaptation in a precoded MIMO system, comprising:
receiving first channel quality information γCQI; with respect to at least one layer r in a plurality of layers in a link,
obtaining a Hybrid Automatic Repeat Request (HARQ) scaling factor μr that is associated with a HARQ feedback; andinterpreting the first channel quality information γCQI into second channel quality information {circumflex over (γ)}r based on at least the HARQ scaling factor μr, wherein the second channel quality information {circumflex over (γ)}r is for adapting the at least one layer r in the plurality of layers. |
