METHODS AND SYSTEMS FOR PRECODER SELECTION ASSISTED BY DEMODULATION REFERENCE SIGNALS (DM-RS) |
| 摘要 |
Systems and methods according to these exemplary embodiments provide for using demodulation reference signals (DM-RSs) to obtain channel state information (CSI) for precoder selection. A method includes: receiving a DM-RS in at least one subframe, determining the CSI from the DM-RS; and using the CSI to perform at least one function. |

1. A method for using demodulation reference signals (DM-RSs) to obtain channel state information (CSI) for precoder selection, the method comprising:
receiving a DM-RS in at least one subframe; determining CSI based on the DM-RS; demodulating user data received during the subframe using the DM-RS; and using the CSI obtained from the DM-RS to perform at least one function. |
