Abstract: Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., client device or a server. The apparatus may transmit, to a server at a beginning of a first time period, at least one first head pose associated with a position of the client device, the first time period being synchronized with the server. The apparatus may also receive, from the server during a second time period, at least one first frame including first content based on the at least one first head pose, the second time period being synchronized with the server. Further, the apparatus may display, upon receiving the at least one frame during the second time period, the at least one first frame including the first content.

Abstract: 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.

Abstract: Various embodiments include methods of managing wireless communications between an unmanned aerial vehicle (UAV) and a controller of the UAV. The methods may include determining whether an indicator of current channel conditions for wireless communications over a first channel equals or exceeds a channel impairment threshold. The indicator of current channel conditions may include at least one of a Doppler speed or a distance between the UAV and the controller. The methods may also include changing from the first channel to a second channel for the wireless communications in response to determining that the indicator of current channel conditions for the wireless communications over the first channel equals or exceeds the channel impairment threshold.

Abstract: Seamless path switching is made possible in a multi-hop network based upon stream marker packets and additional path distinguishing operations. A device receiving out-of-order packets on the same ingress interface is capable of determining a proper order for the incoming packets having different upstream paths. Packets may be reordered at a relay device or a destination device based upon where a path update is initiated. Reordering packets from the various upstream paths may be dependent upon a type of service associated with the packet.

Abstract: A hybrid device may independently select a next hop for a packet stream based upon a path selection algorithm. The path selection algorithm includes calculating end-to-end path capacity for candidate paths to a destination device. End-to-end path capacity is calculated based upon contention groups of particular links in at least one of the plurality of paths. Selected paths are recorded in a stream forwarding table for use with subsequent packets of a packet stream.

Abstract: 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.

Abstract: This disclosure provides systems, methods and apparatus for synchronous channel access control of a wireless system. In some aspects, a device may use a TWT session to communicate with a second device during one or more TWT service periods. Uplink and downlink communications may be coordinated to both be in a TWT service period to allow a device to enter a low power mode outside of the TWT service period. The TWT session, including the service periods, may be configured and managed by the device or the second device to ensure the communications associated with an XR experience between the devices (such as pose data frames or tracking frames provided as uplink data and video data frames provided as downlink data) meet latency requirements or other requirements for the XR experience. Use of TWT service periods allows other devices to use the wireless medium outside of the TWT service periods.

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.
