Abstract: Disclosed herein are a system, a method and a device for switching between different communications protocols. A head wearable display can transmit, to a console during a first session interval, a first request to switch from a first link using a first communication protocol to a second link using a second communication protocol. The first request can include at least one characteristic of the first link. The head wearable display can receive, from the console, a first response to the first request, to perform a switch from the first link to the second link. The first response can indicate a wake up time and a second session interval to perform the switch. The head wearable display can switch from the first link to the second link in the second session interval and after the wake up time.

Abstract: Disclosed herein are systems and methods for facilitating wireless communication of a wearable device. In one aspect, a wireless device receives a paging message from a cellular network, via a wireless link between the wireless device and a companion device. The paging message can be received while a cellular modem of the wireless device is operating in reduced power mode and not registered with the cellular network, and the companion device is registered with the cellular network. The wireless device can transition the cellular modem from the reduced power mode to an active mode in response to receiving the paging message via the wireless link with the companion device. The wireless device can register with the cellular network after the modem has transitioned to active mode, to establish a cellular link directly with the cellular network.

Abstract: Disclosed herein are related to a system and a method of remotely rendering artificial reality. In one approach, a console determines an expected transmission end time of a first session for wireless transmission of image data indicating an image of artificial reality to a head wearable display. In one approach, the console determines an expected process end time of generating additional data associated with the image of the artificial reality. In one approach, the console compares the expected transmission end time and the expected process end time. The console may transmit, to the head wearable display in the first session, the additional data together with the image data, in response to the expected process end time being less than the expected transmission end time.

Abstract: Disclosed herein are related to a first device to communicate with an access point and a second device. In one aspect, the first device communicates with the access point during the first time interval through a first wireless communication. In one aspect, the first device prevents communication with the access point during the second time interval. In one aspect, the first device communicates, as a soft access point, with a second device during the third time interval within the second time interval through a second wireless communication, the third time interval shorter than the second time interval.

Abstract: A first device may include a processor, a first wireless network interface, and a second wireless network interface. The processor may be configured to, while associating with the access point over a first wireless network on a first channel via the first wireless network interface, establish a second wireless network via the second wireless network interface. A group of client devices including one or more client devices can join the second wireless network on the first channel via the second wireless network interface. The processor may be configured to receive, via the first wireless network interface, first information from the access point. The processor may be configured to send, via the second wireless network interface, the first information to the group of client devices.

Abstract: A method by a rendering device includes receiving a request to render multiple surfaces corresponding to multiple virtual objects to be concurrently displayed on an augmented-reality (AR) headset. The method further includes that the AR headset is connected to the rendering device via a wireless link. In response to a determination that a network quality of the wireless link is below a threshold condition, the method further includes selecting a first subset of the multiple surfaces that are higher priority than a second subset of the plurality of surfaces. The method includes transmitting the first subset of multiple surfaces to the AR headset for display and transmitting the second subset of multiple surfaces to the AR headset for display after transmitting the first subset. This method includes rendering the surfaces in accordance with a set of rendering parameters so as to satisfy one or more network constraints.

Abstract: Systems and methods for iterative distributed beam selection include a device including at least one of a first head wearable display (HWD), a second HWD, a first console or a second console. The device detects a predefined condition. The device performs a first distributed beam selection responsive to detecting the predefined condition. Performing the first distributed beam selection includes performing beamforming to provide a first plurality of beams for a first link between the first HWD and the first console, selecting a first beam of the first link with a highest signal-to-interference-plus-noise ratio (SINR) from the first plurality of beams, performing beamforming to provide a second plurality of beams for a second link between the second HWD and the second console while the first beam of the first link is active, and selecting a second beam of the second link with a highest SINR from the second plurality of beams.

Abstract: Disclosed herein are related to coordinating communication among a first access point, a first station device, a second access point, and a second station device. In one aspect, the second access point receives, from the first access point, a first beacon of the first access point at a first beacon transmission time. The first beacon may indicate an offset between the first beacon transmission time of the first beacon and a first data transmission time of the first access point for communication between the first access point and a first station device. In one aspect, the second access point may determine, according to the offset, a second data transmission time of the second access point to be distinct from the first data transmission time of the first access point. The second access point may communicate with a second station device, according to the second data transmission time.
