  • Patent number: 11991260
    Abstract: A user equipment (UE) or other device performs service discovery of edge computing resources in a cellular network system and dynamic offloading of UE application tasks to discovered edge computing resources. As part of the discovery process, the device (e.g., the UE) may request edge server site capability information. When performing dynamic offloading, the UE may obtain (collect and/or receive) information regarding channel conditions, cellular network parameters or application requirements and dynamically determine whether a task of the application executing on the UE should be offloaded to an edge server or executed locally on the UE. In making decisions between offloaded or local execution, the UE may use a utility function that takes into account factors such as relative differences in application latency, energy consumption and offloading cost.

  • Patent number: 11990932
    Abstract: A clock buffer or driver is gated pending reception of verifiable crypto keys. These clock buffer or divers remain gated, thus disabling a processor from any meaningful function, till crypto keys are decoded, verified, and applied to the clock buffer or driver. A low frequency pseudorandom frequency hopping time sequence is generated and used for randomizing spread-spectrum to modulate a reference clock (or output clock) of a frequency synthesizer. This hopping time sequence holds the key to unlocking the crypto keys. The PWM modulated crypto keys are carried by the hopping time sequence. To decode the PWM modulated crypto keys, the hopping time sequence is used. The reference clock which is modulated with crypto keys in the spread-spectrum is sent to a decoder (in a processor) along with the hopping time sequence. The crypto keys are decoded and then used to un-gate the clock buffer.

  • Patent number: 11916718
    Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.
