Millimeterwave access architecture with rapid rerouting

Abstract: In accordance with the exemplary embodiments of the invention there is provided at least a method and apparatus to determine information comprising a direction and a strength of signaling associated with a mobile apparatus, where the apparatus is configured to connect with a cluster of more than one access point; retain the determined information of the signaling associated with the mobile apparatus; and communicate the information of at least the strength of the signaling towards the cluster of the more than one access point. Further, to determine with signaling received at a mobile apparatus from at least one access point information including a direction and strength of the signaling; retain the determined information of the signaling; use the retained information, identify the access point with the signaling having a strongest beam; and reroute communications with the apparatus towards the access point with the signaling having the strongest beam.

Vertical beam design for UE-specific beamforming by matching to a CB

Abstract: A method includes transmitting reference signals to user equipment from an active antenna array system including a multiple of antennas arrayed in at least a vertical direction. The active antenna array system is configured to perform the transmitting of the reference signals using multiple vertical beams having vertical patterns designed to provide desired vertical patterns after codebook feedback from a codebook is applied on transmissions from logical ports of the antenna array. The method includes receiving codebook feedback from the user equipment in response to transmitting the reference signals. The method includes transmitting information to the user equipment at least by applying selected entries of the codebook corresponding to the codebook feedback to the logical ports of the antenna array, wherein application of the selected entries causes the active antenna array system to perform transmitting information using multiple beams having the desired vertical patterns. Apparatus and program products are disclosed.
