Abstract: This disclosure details a base station and client devices using dynamic spectrum access for communication within a frequency spectrum by selecting channels dynamically for efficient communication. This includes identifying active uplink and downlink channels from an available list and allocating them to multiple client devices based on their locations, with some devices sharing common active channels. A downlink channel is designated as a beaconing channel, used for beaconing with embedded information, including the coordinates of a region among a plurality of regions, available channels for the region, and a buffer slot in the channels, during a beaconing period occurring outside regular transmission times. Acknowledgments with medium access control (MAC) commands for an identified subset of client devices sharing an active channel are grouped and transmitted, with each message in the plurality of messages on the uplink channels followed by a downlink acknowledgment.

Abstract: The techniques disclosed herein enable systems to optimize generation and dispatch of renewable energies using data-driven models. In many contexts, a renewable energy system is collocated with a local consumer such as a datacenter, a smart building, and so forth. The objective of the renewable energy system is to meet local power needs while participating in various energy markets of differing trading frequencies. To optimally manage the renewable energy system, a data-driven model is configured to analyze current conditions and generate policies to control renewable energy system operations. For instance, the model can retrieve current market prices, generation capacity, costs associated with generating energy, and so forth. Based on the collected information, the model can generate a policy that maximizes revenue obtained by the renewable energy system while meeting local demand. Through many iterations, the model can determine a realistically optimal policy for managing the renewable energy system.

Abstract: A device and method for managing communication frequencies, including generating a geographical grid with a plurality of cells and allocating communication frequencies to the cells. Each of the communication frequencies is used for communication between a satellite and a ground device or ground IoT modem. A communication frequency allocated to one cell is different from the communication frequencies allocated to each of the immediately surrounding cells. A set of communication frequencies is selected for communication between the satellite and ground devices based on a ground track of the satellite. The selected set is transmitted to the satellite to communicate with the ground station located in a cell with the communication frequency allocated to that cell.

Abstract: Techniques are described herein for reducing the computing cost of decision-making when simulating a real-world system. A machine learning model is trained using data generated by a simulator of the real-world system. Knowledge about how the simulator is implemented is used to improve the efficiency of the machine learning model and to improve the relevance of data selected to train the machine learning model. For example, structural knowledge—the flow of input variables through components of the simulator—is used to determine a causal relationship between input variables. Having identified the causal relationship, the number of simulator iterations used to generate training data may be reduced. Furthermore, large complex machine learning models may be replaced with smaller, more efficient models. Additionally, or alternatively, causal relationships between input variables are identified during training, enabling further refinement of input selection and model design.

Abstract: The disclosure described herein configures a base station and client devices for communication using dynamic spectrum access within a frequency spectrum that includes selecting, from a list of available channels, a set of channels as active channels. The active channels include uplink channels and downlink channels, and the active channels are distributed among a plurality of base station radios of a base station. A different channel is assigned to different base station radios. At least one uplink channel and at least one downlink channel are assigned to a plurality of client devices based on locations the client devices, wherein at least some client devices have active channels in common. The client devices having the active channels in common are also grouped on shared channels and time slots assigned to the client devices in the group, thereby allowing narrowband communication over the channels by the client devices.
