Abstract: Aspects of the disclosure provide for an end user premises device that includes a memory, one or more transceivers, and one or more processors. The one or more processors are configured to receive a user request for data and determine a time to retrieve the data that is during an off-peak time for a network. The retrieval time is determined based on a time when the data will likely be accessed by a client device. At the determined retrieval time, the data is retrieved via the network and stored in the memory. In response to another user request, the data is transmitted to the client device. The one or more processors are optionally also configured to predict data that will likely be accessed by the client device and to retrieve the predicted data during an off-peak time for the network and before a time when the data will likely be accessed.

Abstract: Wireless service is provided to a service area using limited resources dynamically reallocated to maximize capacity in high demand regions. An antenna array transmits a plurality of downlink beams, each covering a respective region of a service area. An antenna management logic identifies a high demand region serviced by downlink beams transmitted from a first set of antennas at a first power level and a low demand region serviced by downlink beams transmitted from a second set of antennas at a second power level. The antenna management logic reconfigures the antenna array to provide the wireless service to the high demand region at a power level higher than the first power level, and to provide the wireless service to the low demand region at a power level lower than the second power level, such that the antenna array does not exceed a maximum power level available from a power supply.

Abstract: A communication system includes an antenna system, data processing hardware in communication with the antenna system, and memory hardware in communication with the data processing hardware and the antenna system. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to perform operations. These operations include transmitting a first communication signal to a first coverage area and determining an interference to the first communication signal by a second communication signal. The operations further include reducing the interference to the first communication signal by a second communication signal by at least one of: adjusting the first coverage area; or adjusting a power of the first signal.

Abstract: A method for providing an alert notification to a user in a degraded location includes obtaining incoming call data indicating the mobile terminal is unable to establish a first communication link with a communication terminal for receiving an incoming call using voice over long term evolution. The method also includes providing the alert notification to a user associated with the mobile terminal based on the obtained incoming call data. The alert notification informs the user that the incoming call directed toward the mobile terminal is pending. The method also includes receiving the incoming call from the communication terminal after the mobile terminal moves away from the degraded location and establishes the first communication link with the communication terminal.

Abstract: The systems and methods of the disclosure relate to estimating the location of a remote device, e.g., a mobile phone or other user equipment (“UE”), that is in communication with equipment aboard a high altitude platform (“HAP”). Because the HAP is in motion, the location of the equipment aboard the HAP is not at a fixed location. While this breaks some forms of traditional UE location positioning techniques, it creates new information that can be used instead. Thus, when traditional GPS or ground-station based location services are unavailable, a remote device in communication with equipment aboard a HAP can still be positioned.

Abstract: A frequency domain diversity DVB receiver device includes multiple antenna ports for receiving radio signals, and radio signal processing circuits connected to the antenna ports that convert the received radio signals into digital samples. The digital samples from the different antenna ports time-share a front-end processor which processes the digital samples to provide time-domain symbols. The time-domain symbols are stored in time-domain symbol buffers according to which of the antenna ports the time-domain symbols are received. A fast fourier transform circuit then retrieves the time-domain symbols and converts them frequency-domain symbols, which are then stored one or more frequency-domain symbol buffers according to the antenna ports the corresponding radio signals are received. A diversity processor which combines the frequency-domain symbols from the frequency-domain symbol buffers.

Abstract: Filtering loop and method for maintaining synchronization between a receiver and a transmitter reduces overhead and enables more robust operation. The method includes the step of receiving an error signal corresponding to a synchronization parameter. A first order filter is applied to the error signal such that a residual signal results. The method further provides for compensating the residual signal for drift such that the compensated residual signal estimates a rate of change in the residual signal. By compensating the residual signal for drift, difficulties associated with time lag and signal degradation are obviated.

Abstract: A system and method are provided for masking messages intended for a particular one of a plurality of receivers receiving messages on the same frequency in a satellite communication system. Each message contains a data portion and a parity portion. Before transmitting the message, the parity portion is masked by performing an exclusive-OR operation on the parity portion using a mask identified with the intended receiver. At the receiver, the parity portion of received messages are first unmasked by performing an exclusive-OR operation on the masked parity portion. The message is accepted by the receive only if the parity check is valid after the unmasking operation.
