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: 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).
