Abstract: This disclosure provides methods, devices and systems for provisioning resources for wireless communications. Some implementations more specifically relate to provisioning such resources based on a mapping of wireless communication devices to a number of time sectors that occur periodically and do not overlap other time sectors. In some aspects, each wireless stations (STAs) in a basic service set (BSS) may be mapped to a respective time sector based on attributes associated with the BSS so that communications between a STA and its associated access point (AP) can only occur within the respective time sector(s) to which the STA is mapped. In some other aspects, each AP in a multi-AP environment may be mapped to a respective time sector based on attributes associated with the multi-AP environment so that communications between an AP and its associated STAs can only occur within the respective time sector(s) to which the AP is mapped.

Abstract: This disclosure provides methods, components, devices and systems for multi-hop support for coordinated medium access. Some aspects more specifically relate to one or more mechanisms according to which an access point (AP) may indicate how many hops a medium access schedule is to be re-announced throughout a wireless network. In some examples, a first AP may select a medium access schedule and may transmit timing information indicative of communication periods associated with the medium access schedule and a value associated with a multi-hop propagation of the timing information. A second AP may receive the timing information and the value and may selectively transmit the timing information in accordance with the value. For example, if the value is indicative of greater than or equal to a threshold hop count value, the second AP may propagate the timing information associated with the communication periods of the first AP.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a packet duration for triggered uplink (UL) transmissions to an access point (AP) from one or more stations (STAs). In one aspect, the AP may estimate an amount of data that a STA has queued for UL transmission and select the packet duration based on the estimated amount of queued UL data. The AP may transmit a trigger frame that solicits UL data from the STA and indicates the selected packet duration. In response, the AP may receive an UL packet from the STA and determine an amount of UL data queued in the STA based on the UL packet. In some implementations, the AP may selectively adjust the packet duration for UL transmissions based on the UL packet, the determined amount of UL data queued in the STA, or both.

Abstract: Systems and methods for selectively enabling multi-user (MU) communications are disclosed. In some implementations, an access point (AP) obtains packets associated with a traffic flow, and obtains at least one of service-level agreement (SLA) parameters associated with the traffic flow, attributes of the traffic flow, or network parameters associated with a basic service set (BSS) that includes the AP. The AP provides an indication of whether the traffic flow is suitable for transmission as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as an MU-MIMO communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication to a WLAN subsystem of the AP, the indication being based on one or more of the SLA parameters, the traffic flow attributes, or the network parameters. The AP initiates transmission of the one or more packets based on the indication.

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.
