Abstract: Example methods and systems for adapting fourth generation (4G) and/or fifth generation (5G) cellular downlink channels in the presence of non-stationary interference are disclosed. An example method, implemented by one or more processors of a cellular base station, includes: receiving, from a user equipment (UE) radio, channel state information (CSI) for a cellular downlink channel between the cellular base station and the UE; determining a signal to interference and noise ratio (SINR) offset based upon the CSI, and a target block error rate (BLER); determining a variance of the SINR offset that represents one or more characteristics of the non-stationary interference; and determining the target BLER based upon the variance of the SINR offset such that the cellular downlink channel adapts to the presence of the non-stationary interference.

Abstract: Techniques for controlling or managing uplink access of a UE to a base station using unlicensed spectrum includes signaling an indication of different uplink access constraints so the UE connects to the base station when the UE and/or the uplink direction between the UE and the base station meet the uplink access constraints. The indication may be broadcast in a reference or synchronization signal, e.g., by utilizing unused or undesignated bits. Uplink access constraints may include a threshold distance of UEs from the base station, interference in the uplink direction (which may differ from interference in the downlink direction), etc. Based on the indicated constraints, the UE may determine whether or not to consider the base station as a candidate serving cell for wireless network access. The UE may be an in-flight aircraft and the base station may be a logical cell of a network that provides in-flight connectivity services.

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: Systems and methods are described for connecting with LEO satellites while reducing emissions toward GEO satellite communications. A system to implement the instant techniques may include a system comprised of a user communications equipment and a LEO constellation. The user equipment (“UE”) may comprise a communications modem and an active antenna unit with a transmit and receive beamformer. In further implementations, the UE may include additional receive only beamformers. The LEO constellation can have a regenerative payload or bent pipe, and can include orbits at different altitudes. Methods as described herein may include a procedure by which the user equipment and LEO satellite work together to identify candidate serving satellites, and select the one that allows to meet the power density requirements to avoid interfering with the GEO satellites.

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: Systems and method for establishing a connection between a vehicle and a base station are provided. The base station sectors are divided into subsector respectively associated with a narrowbeam antenna. To determine the vehicle location without the use of a complementary network, the base station and the vehicle may associate each subsector with a respective set of radio access preamble sequences. Accordingly, the location of the vehicle can be determined based on the particular radio access preamble sequence included in the synchronization messaging. Additionally or alternatively, the base station may be configured to sequentially activate the narrowbeam antennas to detect a which narrowbeam is active when the vehicle responds to a message communicated over the narrowbeams.

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.
