  • Patent number: 9031166
    Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.

  • Patent number: 8929872
    Abstract: Growing demand for high-rate wireless data services is increasing the power consumption requirements of mobile devices. In particular, some smart mobile devices or smart phones are configured to allow multiple software applications to run simultaneously. Some of the applications receive and/or pull data from servers in communication with the network. The more frequently these software applications are provided with access to the data channel the greater the demand on the power supply. Accordingly, there lies a challenge to regulate transmissions to and from a mobile device without adversely impacting quality-of-service (QoS). A method of managing power while maintaining a robust quality-of-service (QoS) is provided by managing the frequency at which a paging channel or the like is monitored. Complimentary methods of changing the frequency of transmission of alerts on a paging channel or the like is also provided.

  • Patent number: 8880004
    Abstract: A device and method for resolving conflicts between air interfaces in a wireless communication system are disclosed. In one embodiment, the method comprises communicating over a first air interface, receiving a request for resources for concurrent use in communicating over a second air interface, determining that a conflict does not exist between resources for the first air interface and at least a portion of the requested resources for the second air interface, and concurrently communicating over the first air interface using resources for the first air interface and communicating over the second air interface using at least a portion of the requested resources for the second air interface.

  • Patent number: 8848771
    Abstract: Systems and methods for simultaneously communicating over multiple air interfaces using a single transceiver are described herein. An input is received at a transceiver. The input has a first signal encoded using a first radio technology and a second signal encoded using a second radio technology. The input is converted from an analog domain to a digital domain. The input is separated into the first signal and the second signal in the digital domain.

  • Patent number: 8599749
    Abstract: Apparatus and methods are described herein for detecting pilot signals. An access terminal determines whether each pilot signal in its active set can be tracked. If not, the access terminal adjusts the search window center associated with any untracked pilot to a position that allows tracking. In some aspects, a known search window center of a tracked member of a same pilot group may be used.

  • Patent number: 8589715
    Abstract: A method and system for correcting timing errors due to thermal changes within a portable computing device are disclosed. The system and method may include calculating an estimate of frequency for a first clock compared to a second clock. The first clock may comprise a crystal oscillator while the second clock comprises a system clock. Next, a sleep state may be calculated for a hardware device, such as radio access technology (“RAT”) module, based on the estimate of frequency for the first clock. An error in the frequency of the first clock that may occur during the sleep state of the hardware device may be calculated. Subsequently, a magnitude of time that corresponds to an actual length of the sleep state relative to the second clock may be calculated so that an internal clock of the hardware devices may be synchronized with the second clock.
