METHODS FOR SELECTING PRECODING VECTORS FOR MULTI-POINT MIMO (MULTIPLE-INPUT-MULTIPLE-OUTPUT) COMMUNICATIONS AND RELATED WIRELESS TERMINALS AND RADIO NETWORK NODES |
| 摘要 |
A wireless terminal may receive multiple-input-multiple-output (MIMO) downlink communications from a wireless communication network including a plurality of base station sector antenna arrays using a codebook of precoding vectors. MIMO downlink communications may be received from the wireless communication. When receiving the MIMO downlink communications as multi-point MIMO downlink communications from first and second base station sector antenna arrays of the plurality of base station sector antenna arrays, a precoding vector may be selected for the multi-point MIMO downlink communications from only a subset of the precoding vectors of the codebook. |

1. A method of operating a wireless terminal in a wireless communication network (60) providing multiple-input-multiple-output (MIMO) downlink communications from a plurality of base station sector antenna arrays using a codebook of precoding vectors, the method comprising:
receiving MIMO downlink communications from the wireless communication network; and when receiving the MIMO downlink communications as multi-point MIMO downlink communications from first and second base station sector antenna arrays of the plurality of base station sector antenna arrays, selecting a precoding vector for the multi-point MIMO downlink communications from only a subset of the precoding vectors of the codebook. |
