摘要： An improved wireless split rendering system for displaying Extended Reality (XR) content is discussed. A rendering server and client head-mounted device (HMD) may communicate over a wireless medium, where communication control is given to a server application layer logic. This allows the server to use request pose information from the HMD only when needed for rendering, while preserving bandwidth on the wireless medium for transmitting frames of the rendered content. This reduces contention and improves channel efficiency.

摘要： Techniques are provided for adaptively controlling an encoding device to allow dynamic insertion intra-coded video content based on feedback information. For example, at least a portion of a video slice of a video frame in a video bitstream can be determined to be missing or corrupted. Feedback information indicating at least the portion of the video slice is missing or corrupted can be sent to an encoding device. An updated video bitstream can be received from the encoding device in response to the feedback information. The updated video bitstream can include at least one intra-coded video slice having a size that is larger than the missing or corrupted video slice. The size of the at least one intra-coded video slice can be determined to cover the missing or corrupted slice and propagated error in the video frame caused by the missing or corrupted slice.

摘要： Described herein are implementations for using a remote control device to control a target device on a network. An exemplary remote control device may generate a data packet comprising a command for controlling the target device and a network address associated with the target device. The remote control device may establish a connection to an infrastructure device on the network, and transmit the data packet to the infrastructure device. The infrastructure device may multicast the data packet to a plurality of IoT devices on the network. An IoT device, of the plurality of IoT devices, may execute the command based on determining, using the network address, that the IoT device is the target device.

摘要： Described herein are implementations for using a remote control device to control a target device on a network via a remote control proxy device. A remote control device may determine an IoT device capable of functioning as a remote control proxy device. The remote control device may generate a data packet comprising a command for controlling the target device and a network address associated with the target device, and transmit the data packet to the IoT device. If the IoT device determines, using the network address, that it is not the target device, the IoT device may either unicast the data packet to the target device or multicast the data packet to multiple intermediate IoT devices on the network.

摘要： A network condition prompts a hybrid device to select a new path for a packet stream. A path update may occur in response to a change in network topology or a traffic loading condition (e.g., congestion or saturation of a link in the current path). Path selections may be made at each hybrid device in the path from a source hybrid device to a destination hybrid device. A path update procedure may be dependent upon path selection procedures that are optimized for a hybrid network in which multiple hybrid devices may be utilized for a particular path. Path update for load balancing may be dependent upon whether a packet stream is elastic or non-elastic.

摘要： A hybrid device can be configured to select a transmit interface to attempt to ensure that each network interface of the hybrid device supports unidirectional traffic. Each of the plurality of network interfaces of the hybrid device can be categorized into one of a set of interface classes based on whether incoming traffic is received at the network interface and/or whether outgoing traffic is transmitted from the network interface. A transmit interface class is selected from the set of interface classes based, at least in part, on a priority level associated with each of the interface classes. One of the network interfaces that belongs to the transmit interface class is selected as a transmit interface for transmitting the frame on the communication network.

摘要： Operations for a WLAN-capable remote control device and a controlled device are disclosed. A first network device (e.g., remote control) may receive a user input for controlling operation of a second network device (e.g., controlled device) of a communication network. The first network device may transition to an active operating state in response to receiving the user input. The first network device may transmit the first user input to the second network device. The first network device may exit the active operating state in response to successfully transmitting the first user input to the second network device.

摘要： This disclosure provides systems, methods and apparatus for asynchronous channel access control of a wireless system. In some aspects, a device may adjust the priority of one or more PPDUs and may perform other operations to ensure control of a wireless medium at certain times while still allowing for other devices to communicate on the wireless medium. For example, the device may adjust a backoff counter or one or more EDCA parameters to ensure obtaining control of the wireless medium to transmit a first PPDU of an application file. For one or more subsequent PPDUs of the application file, the device may again adjust a backoff counter or one or more EDCA parameters to allow other devices to obtain control of the wireless medium in certain scenarios (such as a second device to provide information back to the device or to otherwise transmit using the shared wireless medium).

摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for performing an optimized rate search process. In one aspect, a first device may determine a signal strength measurement based on a result of a beamforming process. The first device may determine the signal strength measurement associated with a transmission sector selected based on a sector level sweep of the beamforming process. The first device may determine a modulation and coding scheme (MCS) for transmissions from the first device to a second device based, at least in part, on the signal strength measurement determined from the beamforming process. In one aspect, the first device may determine the MCS without using probing messages during the rate search process. In one aspect, the first device may determine an initial MCS based on the signal strength measurement, and determine whether to select or change the initial MCS.

摘要： A method for enabling access point discovery in a wireless network includes scanning, at an access point, a low energy protocol advertising channel for beacon information broadcasted from a second access point. The low energy protocol advertising channel is associated with a low energy protocol that is different from a first protocol associated with a primary operating channel of the access point. The method further includes receiving the beacon information at the access point via the low energy protocol advertising channel.
