Abstract: Systems and methods may facilitate initial establishment and/or handover of an air-to-ground (ATG) communication link between an aircraft and a ground-based cellular communication network (e.g., a 5G network). The systems and methods may be particularly applicable for an aircraft having a user equipment (UE) antenna that uses narrow beamforming to connect to a cell of a base station (gNB). The UE identifies candidate cells based upon the location of the UE and locations and orientations of cells in the network, identifies a cell having a higher likelihood of connection success compare to other cells, and directs a beam to the chosen cell. The systems and methods may enable the UE to create neighbor lists in real time based upon the UE location, and may prevent blind searching normally associated with narrow beamforming methods.

Abstract: A vehicle communication system includes a controller configured to be communicatively coupled to one or more antennas. The controller is also configured to adjust a beam during a period of time to be oriented at a plurality of pointing angles, and detect a plurality of sets of signal data for a received signal, where each set of signal data is detected at a different one of the pointing angles. The controller is further configured to identify a particular pointing angle based on the plurality of sets of signal data, reorient another beam from the given pointing angle to the particular pointing angle, and transmit or receive data, via the other beam while the other beam is oriented at the particular pointing angle, between a particular external node and at least one internal node.

Abstract: A first beam is implemented, from a set of vehicle-based antennas, for current or future communication with a ground-based or satellite-based network via an external antenna (e.g., of a base station or satellite). A second beam may be implemented to detect or determine a better pointing angle for the first beam, thereby “fine tuning” the pointing angle for the first beam. Specifically, the second beam may be “swept” through a range of pointing angles while a signal parameter representing signal quality or strength is measured, detected, or calculated at each pointing angle. The values for the signal parameter may be evaluated to identify a desired value and the pointing angle at which the desired value was obtained. The first beam may be reoriented or repointed at the desired pointing angle, and one or more nodes of vehicle-based communication system may communicate with an external network via the first beam.

Abstract: Novel techniques for pooling the available transmit power of a beam across the subcarriers that are or that are scheduled to be in use (and not across all available subcarriers) are disclosed. The scheduled subcarriers may be located in the same or different carriers of a modulation transmitter modulation system, and the pooled transmit power may be allocated or distributed across the scheduled subcarriers of the beam. Modulation symbols or resource elements may be transmitted in accordance with allocated, per-subcarrier power budgets, thereby maximizing the SNIR of signals that are transmitted in the beam via the scheduled subcarriers. Additionally, the allocation of the pooled transmit power to various subcarriers may continuously and/or dynamically vary over time, e.g., based on traffic demands, interference characteristics, etc., as well as based on subsequent scheduling of subcarriers to transmit subsequent modulation symbols or resource elements.

Abstract: Selecting serving cells in air to ground communication systems efficiently and with maximum knowledge of forward and return link channel conditions allows maximum throughput available to a user at any point in time, particularly in the presence of high interference. Airborne based and ground based systems may collect forward and return link channel conditions and develop user capacity estimates to be used by aircraft and ground based transceivers. Such user capacity estimates may be shared among distributed air-to-ground networks to ensure the latest channel conditions are available for serving cell selection decisions.
