Methods and Apparatus for Beamforming |
| 摘要 |
Systems and techniques for carrier aggregated beamforming using elevation control. A base station determines a first elevation to be used for transmission to a user device using a first carrier, for example, based on information received from the user device. A second elevation, for transmission to the user device based on the second carrier, is determined based at least in part on the elevation information determined for the first carrier. The first and second carriers may be used by the same base station or by different base stations, and using elevation information determined for the first carrier to determine elevation information for the second carrier avoids computation and signaling needed for separate determination of the elevation information for the second carrier. |

1. A method comprising:
determining a first elevation beam for transmission to a user device using a first carrier; determining a second elevation beam for transmission to the user device using a second carrier, wherein the selection of the second elevation beam is based at least in part on information relating to selection of the first elevation beam; and configuring the first and second elevation beams for transmission to the user device. |
