  • Publication number: 20230147208
    Abstract: A method and apparatus for offloading idle mode activities from one user equipment (UE) to another. A UE includes a cellular modem, a device-to-device (D2) communication modem, and a processor. The cellular modem performs idle mode activities during an idle mode. The processor controls the cellular modem and the D2D modem. The processor is configured to send information necessary for performing the idle mode activities to the secondary UE for offloading the idle mode activities of the primary UE to the secondary UE and put the cellular modem in a low power state or turn off the cellular modem during the idle mode. The processor wakes up the cellular modem to receive a paging message if a wake-up signal is received from the secondary UE.

  • Publication number: 20220230643
    Abstract: Techniques for teleconferencing with enhanced audio during low-quality connection conditions are disclosed. In the illustrative embodiment, a user of a compute device is teleconferencing with users of one or more remote compute devices. The compute device monitors a connection quality with a remote compute device. If the connection quality drops below a threshold, risking gaps in the audio data, the compute device generates speech code data that can be used to fill in the gaps in the audio data. The remote compute device can use the speech code data to augment the audio data by using a voice model to create additional audio data based on the speech code data.
