  • Publication number: 20190347068
    Abstract: Non-limiting examples of the present disclosure relate to personal history recall, for a received user input, through contextual analysis of user data associated with user usage of applications/services. Examples described herein extend functionality of and enable a virtual assistant to provide efficient and accurate recall processing even in instances where a user provides vague or general description. An exemplary virtual assistant is configured to process user input received through any modality. A virtual assistant is programmed with a skill for custom search processing that adapts operation of the virtual assistant. An exemplary skill for custom search processing provides a layer of intelligence over raw application data to enable the virtual assistant to match user input to a previous context in which a user was executing an application/service. Contextual search ranking and filtering factors in access to content and user activity when evaluating a user input such as a spoken utterance.

  • Patent number: 9497714
    Abstract: A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.

  • Patent number: 9198139
    Abstract: Methods and apparatuses are provided for performing power control for a femto node deployed in a wireless network that include adjusting a transmission parameter of the femto node based on one or more signal energy parameters, such as a received signal strength indicator (RSSI). A comparison between the signal energy, a noise floor, and a threshold signal energy can be determined, and a transmission parameter of the femto node is accordingly adjusted based on the comparison.

  • Publication number: 20150195733
    Abstract: Methods and apparatuses are provided that include deploying a femto node in a wireless network. The femto node can measure received signal quality upon initialization in a wireless network and/or according to a timing. The femto node can determine whether to communicate in the wireless network based on comparing the received signal quality to a threshold signal quality. The timing can be determined based on various factors to ensure fairness among femto nodes initializing in the wireless network. A centralized entity can be used to determine the timing and/or whether a femto node should communicate.

  • Patent number: 8862140
    Abstract: Methods and apparatuses are provided for performing power control for a femto node deployed in a wireless network that include adjusting a transmission parameter of the femto node based on one or more radio frequency (RF) environment parameters. An RF environment parameter can be determined for a femto node related to a location in a coverage area. A different RF environment parameter related to other femto nodes at the location in the coverage area can be received from one or more devices, a network listening module, etc. A transmission parameter of the femto node, such as a transmit power, can be adjusted based on the RF environment parameter and the different RF environment parameter.

  • Publication number: 20120302263
    Abstract: A location of an access terminal is estimated based on uplink signals that a plurality of femto cells receive from the access terminal. The transmit power of the access terminal may be adjusted in some cases to facilitate the reception of signals at the femto cells during a location determination operation. In some embodiments, a location of an access terminal is estimated based on relative path loss values derived from the signals received by the femto cells.

  • Publication number: 20120302261
    Abstract: A location of an access terminal is estimated based on signals received by the access terminal. The manner in which a femto cell transmits signals and/or the manner in which the access terminal monitors for signals may be controlled in some cases to facilitate the reception of signals at the access terminal during a location determination operation. In some embodiments, the number of femto cells for which the access terminal monitors for signals may be controlled by controlling the manner in which the access terminal maintains its active set. In some embodiments, in the event a given femto cell is interfering with the ability of an access terminal to receive signals from other femto cells, that femto cell may be instructed to temporarily stop transmissions (e.g., on the traffic channel and/or a beacon channel).
