  • Patent number: 12200646
    Abstract: A method by a user equipment (UE) includes receiving at least one time offset for scheduling non-terrestrial communications. The at least one first time offset is configured according to a numerology and/or a bandwidth part (BWP). The UE communicates in accordance with the time offset(s). The time offset may be a single time offset that applies across all numerologies or may be multiple time offsets, each specific to a particular numerology or bandwidth part (BWP). The time offset may be a single time offset scaled based on a current numerology configured for communications. The time offset may apply across different bandwidth parts (BWPs) or across multiple component carriers from which the UE is receiving downlink data.

  • Publication number: 20240406228
    Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a first wearable device and a second wearable device to initiate media sessions with a user equipment (UE) and an end device. The wearable devices may each initiate a session flow by transmitting session description protocol (SDP) offer messages to the end device. In some examples, the wearable devices may transmit capability information to the UE, and the UE may transmit an SDP offer message to the end device. The end device may begin the session after receiving the one or more SDP offer messages by transmitting one or more SDP answer messages. The wearable devices may each transmit information about a user of the wearable devices. The end device may generate streams of media content, and the UE may cast the streams of media content to the wearable devices.

  • Publication number: 20240364889
    Abstract: A first device may perform a first part of a computing graph to extract a feature map from media (e.g., video) data. The first device may buffer the media data and compress the feature map. The first device may then send the compressed feature map to a second device, which may perform a second part of the computing graph (e.g., processing tasks), e.g., to perform object detection or other such tasks. The second device may request at least a portion of the buffered media data when needed, e.g., to improve accuracy of the second part of the computing graph/processing tasks. Thus, the second device may send a request to the first device for the at least portion of the buffered media data, then perform the second part of the computing graph using the buffered media data and the received feature map.

  • Patent number: 12126540
    Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites and base stations or gateways in a non-terrestrial network (NTN). Due to the large distances between transmitting devices and receiving devices in a NTN, timing adjustments to account for propagation delay communications links via a satellite may include a propagation delay between a UE and a satellite, a propagation delay between a base station and a satellite, as well as a variation in the propagation delays due to movement of the satellite. In accordance with various techniques discussed herein, a UE may account for variation in propagation delay, in addition to determined propagation delay, when determining an uplink timing for uplink communications via a satellite.
