摘要： A method of communicating with satellites in a low-earth orbit (LEO) constellation includes determining, by a controller of a mobile communicator mounted on a mobile platform, one or more conditions corresponding to a plurality of spatial channels associated with multiple satellites in the LEO constellation, and allocating, by the controller and based on the one or more conditions, a plurality of antenna resources of a phased array antenna to each of two or more satellites included in the multiple satellites in the LEO constellation. Each of the plurality of antenna resources includes a respective antenna element and a respective phase controller. The method also includes commanding, by the controller, one or more transceivers to establish simultaneous communicative connections to the two or more satellites via the allocated plurality of antenna resources.

摘要： The present application provides a resource allocation method for a unmanned aerial vehicle (UAV)-assisted symbiotic radio system, which addresses the problem of how to improve the system transmission rate in a multi-IoT device scenario. A passive sensor data collection mechanism based on a UAV-assisted symbiotic radio communication system under multiple backscatter devices (BDs) is proposed. When the base station sends signals to the cellular users, multiple IoT BDs on the ground perform energy collection and backscatter of RF signals sent by the base station, and the UAV receives backscatter signals from the BDs and collects the data from all the BDs on the ground, i.e., all the BDs share RF sources with the cellular users.

摘要： An aerial-floating type communication relay apparatus (HAPS) is provided, which can perform a dynamic area control capable of coping with a change of distribution of terminal apparatuses in a service area configured with plural cells formed toward the ground, and that can suppress an increase of time required for area optimization. The aerial-staying type communication relay apparatus (HAPS) estimates positions of plural terminal apparatuses located in a service area, divides plural (L) kinds of antenna parameters of an antenna for service link into plural parameter groups, optimizes the antenna parameters based on estimation results of positions of the plural terminal apparatuses, for each of the parameter groups, and applies, to the antenna for service link, the optimum values of the plural (L) kinds of antenna parameters after completing the optimization for each of the parameter groups.

摘要： A method for correcting frequency and/or phase in a communication link; a communication network; and a multiplexing and phase compensation unit are disclosed. The method for correcting frequency and/or phase in a communication link comprises receiving at least one reference transmission communicated via a wireless communication link; providing at least one identified characteristic by identifying at least one characteristic of the reference transmission; comparing said identified characteristic with at least one expected characteristic; and correcting a shift in frequency and/or phase of at least one communication signal communicated via the communication link based on a difference between the identified characteristic and the expected characteristic.

摘要： A method implemented by a system for security comprising an unmanned aerial vehicle (UAV) and an analytics device configured to communicate with a remote monitoring system and the UAV is provided. Media data from the UAV is received at an analytics device, where the media data includes surveillance information corresponding to a premises under surveillance. Security attributes associated with the premises are detected based at least in part on a first level of machine learning (ML) analysis performed on the media data. The media data are transmitted by the analytics device to the remote monitoring system for a second level of ML analysis based at least in part on the security attribute, where the first level of ML analysis is less computationally expensive compared to the second level of ML analysis, and the second level of ML analysis is performed at the remote monitoring system on the media data.
