20160050002 | FLEXIBLE ELEVATION BEAMFORMING - Flexible beamforming is disclosed in which a base station receives feedback from a user equipment (UE), in which the feedback is related to one or more reference signals transmitted by the base station. The base station will obtain a tilt adjustment based, at least in part, on the feedback and generate an elevation precoding vector based using the feed-back. Using the tilt adjustment and elevation precoding vector, the base station may then perform elevation beamforming with an antenna array of the base station for the UE. | 02-18-2016 |
