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, 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: This disclosure provides methods, apparatuses, wireless nodes and computer-readable mediums for wireless communications. In one aspect, a method is provide for dynamic selection and triggering of uplink (UL) transmission (TX) modes. A method that may be performed by an access point (AP) includes dynamically selecting an UL single user (SU) TX mode, an UL multiple user (MU) multiple input multiple output (MIMO) TX mode, or an UL orthogonal frequency division multiple access (OFDMA) TX mode. The AP communicates with one or more stations (STAs) based on the dynamically selected UL TX mode.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a plurality of TCP ACKs, and at least one of TCP data or UDP data for a multi-user transmission to a set of STAs. The apparatus may allocate the plurality of TCP ACKs to a PPDU before allocating the at least one of the TCP data and the UDP data to the PPDU. In certain aspects, the plurality of TCP ACKs may be frequency division multiplexed in the PPDU. In certain other aspects, the apparatus may transmit, to the set of STAs, the multi-user transmission including at least the plurality of frequency division multiplexed TCP ACKs.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a set of STAs for at least one of a MU-MIMO transmission or an OFDMA transmission. In certain aspects, the set of STAs may be associated with a set of acceptable MCSs determined based on MCSs excluded from a union of a plurality of sets of unacceptable MCSs. In certain other aspects, each set of unacceptable MCSs in the plurality of sets of unacceptable MCSs may be associated with a different STA in the set of STAs. The apparatus may transmit the at least one of the MU-MIMO transmission or the OFDMA transmission to the set of STAs.

Abstract: Aspects of the present disclosure relate to a pre-fetching architecture and scheduler for multi-station APs. An example method generally includes fetching, from a plurality of host buffers, descriptive information for a set of packets based, at least in part, on an amount of descriptive information already cached for transmission to one or more target devices; using the fetched descriptive information to obtain the set of packets; and transmitting the set of packets to the one or more target devices.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing access in a wireless local area network (WLAN) to support the quality of service (QoS) associated with a service of a wireless communication system. In one aspect, an access device may create a traffic flow between a station (STA) of the WLAN and Na network slice of the wireless communication system. The access device (such as a 5G customer premises equipment (5G-CPE)) may route traffic between the network slice and the STA based on the QoS associated with the network slice. Thus, in some implementations, the QoS for the network slice can be extended into the WLAN.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In some implementations, a wireless communication device obtains one or more indications that a wireless station (STA) will enter a power-save mode, selects, for each respective STA of a plurality of STAs, a duration associated with the respective STA entering the power-save mode, and adjusts one or more parameters of a multi-user channel access mechanism for transmitting uplink data associated with the selected duration. In some other implementations, a wireless communication device outputs one or more indications that the device will enter a power-save mode, outputs or obtains data at each of a plurality of first instances, enters the power-save mode at each of a plurality of second instances, and obtains a beacon indicating one or more parameters to be used for a multi-user channel access mechanism for transmitting uplink data.
