Patent number: 11943022Abstract: 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.Type: GrantFiled: March 29, 2019Date of Patent: March 26, 2024Assignee: Intel CorporationInventors: Venkatesan Nallampatti Ekambaram, Yang-Seok Choi, Junyoung Nam, Feng Xue, Shu-ping Yeh, Hosein Nikopour, Shilpa Talwar, Jan Schreck, Nageen Himayat, Sagar Dhakal

Patent number: 11553511Abstract: Embodiments of the present disclosure describe methods, apparatuses, and systems for enhanced control signaling using full-duplex communication in wireless communication networks. A base station may schedule a first user equipment (UE) for primary access to a set of time-frequency resources in a first communication direction (e.g., uplink or downlink).
