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: A method includes determining, based on a first packet error rate (PER) associated with a first communication data rate of data sent from a first electronic device to a second electronic device, a predicted second PER associated with a second communication data rate by increasing a value of the predicted second PER based on a first signal-to-noise ratio (SNR) sensitivity associated with the first communication data rate being less than a second SNR sensitivity associated with the second communication data rate or by decreasing the value of the predicted second PER based on the first SNR sensitivity being greater than the second SNR sensitivity. The method further includes selecting a communication data rate for communication from the first electronic device to the second electronic device based at least in part on the first PER and the predicted second PER.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.

Abstract: A method includes determining, at a first transmitter, whether to permit reuse of a first transmit opportunity (TXOP) associated with a message. The method further includes sending a portion of the message from the first transmitter to a first receiver. The portion of the message indicates whether reuse, by a reuse transmitter, of the first TXOP is permitted. When reuse of the first TXOP is permitted, the reuse transmitter is permitted to send a second message while the first transmitter sends a second portion of the message to the first receiver during the first TXOP.
Abstract translation: 一种方法包括在第一发射机处确定是否允许与消息相关联的第一发射机会（TXOP）的重用。 该方法还包括将消息的一部分从第一发射机发送到第一接收机。 消息的部分指示是否允许由重用发射机重用第一TXOP。 当允许第一TXOP的重用时，允许重用发送器发送第二消息，同时第一发送器在第一TXOP期间向第一接收器发送消息的第二部分。

Abstract: A method includes sending, from a first transmitter to a first receiver, a request to send (RTS) message associated with a first transmit opportunity (TXOP). The RTS message requests the first receiver to indicate whether reuse of the first TXOP is permitted. The method further includes receiving, at the first transmitter from the first receiver, a clear to send (CTS) message responsive to the RTS message.

Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media that support station performance enhancement with multi-link operations. An example method may include determining at least one network metric related to at least one link between a station (STA) and access points (APs) and determining at least one connection parameter related to at least one application operating on the STA. The method may include selecting a mode of multi-link operations based at least in part on the network metric and the connection parameter, wherein the mode of multi-link operations comprises one or more of: a multi-link mode in which the STA operates over a first link and a second link at a same time or a single-link mode in which the STA operates over one of the first or second links and communicating with the one or more APs according to the selected mode.

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).
