Feedback Methodology for Per-User Elevation MIMO |
| 摘要 |
A method includes receiving downlink reference signals from a transmit antenna array having of rows of azimuth antenna elements and columns of elevation antenna elements; computing first channel state information feedback components assuming azimuth-only adaptation; computing second channel state information feedback components assuming elevation-only adaptation; computing third channel state information feedback components assuming elevation-adaptation and elevation adaptation; and feeding back the first, second and third channel state information feedback components. |
