Abstract: Various embodiments include methods implemented in user equipment (UE) for synchronizing resource timings of at least two wireless protocols. The UE may obtain communication timing information of a user device, send the communication timing information of the user device to a network node, and configure first resource timings of an uplink or downlink between the UE and the user device based on the communication timing information. The UE may request configuration of second resource timings of a further uplink or downlink between the UE and the network node based on the communication timing information. Sending communication timing information may include requesting a discontinuous reception (DRX) configuration adjustment so that a DRX cycle of the UE and a target wake time (TWT) of the user device at least partially coincide. Configuring first resource timings may include adjusting a timing of the TWT based on a DRX configuration for the user device.

Abstract: 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).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a connected device, an indication associated with management of one or more communications between the connected device and a network node of a wireless network, wherein the one or more communications are carried by the UE between the connected device and the network node. The UE may configure, based at least in part on the indication, the UE for carrying the one or more communications between the connected device and the network node. Numerous other aspects are described.

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: 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.

Abstract: Disclosed are systems and techniques for extended reality optimizations using radio frequency (RF) sensing. An example method can include obtaining RF sensing data; determining, based on the RF sensing data, reflected paths of one or more reflected RF signals, each reflected RF signal including a reflection of a transmitted signal from one or more objects in physical space; comparing the one or more reflected paths, to a field-of-view (FOV) of an image sensor of the device; and based on the comparison, triggering an action by the device and/or the image sensor.

Abstract: 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.
