  • Patent number: 9986584
    Abstract: Disclosed is a method and apparatus to help manage data communication in a manner that increases downlink capacity. As disclosed, a base station may transmit, in a downlink traffic channel of a given sub-frame, bearer data to a particular wireless communication device (WCD). After transmitting the bearer data, the base station may transmit, in the downlink control channel of another sub-frame, a signaling message that directs the particular WCD to read the previously transmitted bearer data. The signaling message may include an indication of the given sub-frame having the previously transmitted bearer data. When the WCD receives and reads the signaling message, the WCD may use the indication as a basis to read the previously transmitted bearer data in accordance with the signaling message.

  • Patent number: 9872263
    Abstract: The invention is directed to methods and systems for generating reference signals from radio signals received from a large-coverage access component, such as a base station. The radio signals are received, analyzed, and selected based on the analysis. The selected signals are processed by an oscillator to filter out abnormalities. Consequently, a reference signal is generated that is encapsulated into packets and delivered to one or more small-coverage access components using the Precision Timing Protocol or some other protocol that is useable by the small-coverage access components. The small-coverage access components comprise one or more of a femtocell or a picocell.

  • Patent number: 9844014
    Abstract: Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality.

  • Patent number: 9807628
    Abstract: A loss of connection between a wireless access point and a network is reported to a network-based service platform by the wireless access point by automatically establishing wireless contact with a second wireless access point, and transmits a predetermined fault report message to a predetermined network platform address by way of the second wireless access point and the second network interface. Authentication credentials are stored in the access point allowing automatic access to the service platform without user intervention, to allow the report to be generated without user intervention. The message may include data on recent usage of the access point, or may be repeated when a user attempts to use the access point, in order to prioritize the fault reported at the service platform.

  • Patent number: 9794024
    Abstract: Aspects of the present invention provide apparatuses and methods for adaptive channel state feedback (CSF) estimation techniques. Downlink transmissions can be received at a mobile device. The downlink transmissions can be received after the mobile device has entered a power saving mode of operation. The downlink transmission received can be a discontinuous downlink subframe and can include one or more pilot symbols. A channel variation factor of the transmission channel can be determined based on the received downlink transmission. Based on the amount of variation of the transmission channel, either an earlier-received or a later-received pilot symbol can be used for CSF estimation. Further, either higher or lower weighted filter coefficients can be selected for use in CSF estimation based on the amount of variation of the transmission channel.
