摘要： Disclosed herein are related to a first device to communicate with a second device and a third device. In one aspect, the first device determines a first time interval to receive a first beacon frame from the second device. In one aspect, the first device determines, according to the first time interval, a second time interval for the first device to transmit a second beacon frame to a third device. In one aspect, the first device determines a third time interval to operate the first device in a wake up mode. The third time interval may encompass the first time interval and the second time interval. In one aspect, the first device receives the first beacon frame from the second device during the first time interval, and transmits the second beacon frame to the third device during the second time interval.

摘要： Disclosed herein a system, a method and a device for selecting between a primary link and a secondary link for AR/VR applications. A console can provide a VR/AR session to a user through a head wearable display. The console can determine that a first measurement of a primary link between the console and a head wearable display is less than a first threshold. The first measurement can include a quality metric of the primary link. The console can activate a secondary link between the console and the head wearable display. The console can determine whether a second measurement of the primary link between the console and the head wearable display is less than a second threshold. The console can transition when the second measurement is less than the second threshold, traffic on the primary link to the activated secondary link.

摘要： 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.

摘要： Disclosed herein are related to a system and a method of coordinating among artificial reality links. In one approach, a system comprising a first console for executing an application for artificial reality may include a wireless communication interface and a processor. The processor may be configured to send, via the wireless communication interface, a first message comprising a first plurality of parameters and a first schedule for access to a shared wireless channel by the first console, receive, from a second console via the wireless communication interface, a second message comprising a second plurality of parameters and a second schedule for access to the shared wireless channel by the second console, update, responsive to the second message, the first plurality of parameters and the first schedule, and/or send, via the wireless communication interface, a third message comprising the updated first plurality of parameters and the updated first schedule.

摘要： 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.

摘要： 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.

摘要： Disclosed herein are related to a system and a method of enforcing fairness in airtime utilization among devices including artificial reality devices. In one approach, a system as a first device may be configured to monitor, via the wireless communication interface, a wireless channel. The processor may be configured to determine information about other devices using the wireless channel. The processor may be configured to determine a target share of the wireless channel for use by the first device in communicating data for the artificial reality, according to the information about the other devices using the wireless channel. The processor may be configured to access, via the wireless communication interface, the wireless channel according to (1) the target share of the wireless channel and (2) a combined level of usage of the wireless channel by the first device and the other devices.

摘要： Disclosed herein are related to a system and a method of time alignment in an AR/VR environment. In one approach, a device including a console or head wearable display (HWD) may determine a wireless transfer window corresponding to a wireless data transmission between the HWD and the console. The device may determine one or more first processes to be performed by the device to enable the wireless data transmission. The device may schedule the one or more first processes according to the wireless transfer window. The device may perform the wireless data transmission within the wireless transfer window responsive to the one or more first processes.
