    Abstract: A method and system for interference cancellation in a wireless communication device. The wireless communication device can include an interference estimator configured to generate one or more filter weights based on a transmit signal. The one or more filter weights can be generated based on one or more kernels generated by the interference estimator. The interference estimator can be configured to perform recursive linear square (RLS) estimations based on the one or more kernels. The RLS estimations can include one or more independent RLS estimations, one or more parallel RLS estimations and/or one or more cascade RLS estimations. The interference estimator can be configured to perform one or more orthogonally transform one or more kernels.

    Abstract: Technology to adaptively sectorize a spatial region for parallel multi-user transmissions is disclosed. In an example, a node (e.g., evolved Node B (eNB)) can include computer circuitry configured to: Generate a set of precoding matrices for a set of beam cones in the spatial region; and generate a beam cone for multi-user beamforming transmissions using system information for the beam cone. A precoding matrix in the set of precoding matrices can be used for each beam cone, and each beam cone can cover a beam cone spatial region that differs from another beam cone spatial region of another beam cone in the spatial region. Each beam cone can include system information that differs from the system information of the other beam cones in the spatial region.

    Abstract: Systems and methods of beamforming and improving mmWave communications for drones are described. Multiple RF chains are used to adapt the main beam to track changes without the use of pilot signals. To reduce interference, interfering signal power is eliminated by optimizing a non-Gaussian measure to extract the interferers. The AoA of signals from a target drone on neighbouring drones and location of the neighbouring drones and base stations are used to independently corroborate the location reported by the target drone. The base station provides additional synchronization signals below 6 GHz and restricts the search/measurement space in the vertical direction. The inherent sparse structure above 6 GHz is exploited by applying different beamformers on a sounding signal and estimating the AoA and impulse response. Variations of fully digital and hybrid beamforming architectures for multi-cell DL sync and CRS measurement are described.
