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.

Synchronous channel access control of a wireless system

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

Wireless network configuration for low-latency applications

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.

Synchronization techniques in split rendering

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).

Asynchronous channel access control of a wireless system

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.

Cross layer traffic optimization for split XR

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.

Dynamic video insertion based on feedback information

Methods and apparatuses for communicating in a wireless communication network are disclosed. For example, one method includes determining, by a first access point, a polling schedule for communicating with one or more wireless stations on a first wireless communication channel, the polling schedule for a second access point on a second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, transmission information to the one or more wireless stations, wherein the transmission information comprises information for the one or more wireless stations to receive a transmission from the second access point on the second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, one or more packets to at least one of the one or more wireless stations in accordance with the polling schedule.

Methods and apparatus for multi-channel medium access control protocol

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.

Controlling an IoT device using a remote control device via an infrastructure device

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.

Seamless switching for multihop hybrid networks

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.

Distributed path selection in hybrid networks

Various aspects are provided for wireless communication channel management. For instance, aspects of an example method are provided, the method including detecting a trigger condition for changing an operating frequency of a wireless communication link between a first device and a second device. In addition, the example method may include obtaining a target operating frequency for the wireless communication link based on detecting the trigger condition. Moreover, the example method may include tuning a transceiver to the target operating frequency. In an example, the first device may be an unmanned aerial vehicle (UAV) and the second device may be a controller associated with the UAV. Additionally, example apparatuses and computer-readable media are provided for wireless communication channel management, the example apparatuses and computer-readable media being configured to perform, or store computer-executable code to perform, the disclosed example methods.

Synchronization of interactivity with linear advertisement in a mobile broadcast network

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.
