TL;DR: In this article, the uplink access configuration index is used to identify an uplink AP from among a predetermined plurality of AP configurations, and then the AP is transmitted to the wireless communications network according to the identified AP.

Coordinated 3D beamforming for interference management in cellular networks
TL;DR: A novel transmission technique in which intercell interference management is performed via coordinating the beamforming jointly in the horizontal and vertical planes of the wireless channel, denoted as coordinated 3D beamforming is proposed.
Proceedings ArticleDOI
15 GHz propagation properties assessed with 5G radio access prototype
TL;DR: This paper presents coverage and penetration loss measurements in an urban environment at 15 GHz to provide insight into the design and deployment of future 5G systems in higher frequency bands andentials of beamforming as a means to improve the coverage.
Journal ArticleDOI
Adaptive Multicell 3-D Beamforming in Multiantenna Cellular Networks
TL;DR: A novel hybrid multicell cooperation technique is proposed in which the intercell interference is controlled via either cooperative beamforming in the horizontal plane or coordinated beamform in the vertical plane of the wireless channel, which is denoted as adaptiveMulticell 3-D beamforming.
Journal ArticleDOI
Throughput Optimization for MISO Interference Channels via Coordinated User-Specific Tilting
TL;DR: Simulation results show that the proposed coordinated user-specific tilting scheme outperforms the conventional schemes employing a fixed tilt angle at each BS.
