  • Patent number: 11601883
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.
