Abstract: Certain aspects of the present disclosure provide an architecture and method for multi-link operation (MLO) at an access point (AP). The method generally includes obtaining a packet from at least one buffer and selecting a processing path, from first and second processing paths, for a packet to be routed from the at least one buffer to at least one of a plurality of radio components for wireless transmission to at least one peer via one or more links, wherein: the first processing path is configured to bind the packet to one of the one or more links based on at least one code-implemented rule, and the second processing path is configured to bind the packet to one of the one or more links based on instantaneous channel sensing.

Abstract: Aspects are provided for BTM-based load balancing. Various aspects relate generally to a method of load balancing where an AP multi-link device (MLD) recommends that a non-AP MLD move to an indicated set of links of the AP MLD and operate on the indicated set of links without purging context between the AP MLD and the non-AP MLD. In some examples, if the non-AP MLD does not comply, then the non-AP MLD may face disassociation from the AP MLD. Some aspects more specifically relate to recommending that the non-AP MLD move to an indicated set of links of a different AP MLD and operate on the indicated set of links of the different AP MLD after performing a multi-link setup with the different AP MLD. In some examples, the AP MLD may then disassociate from the non-AP MLD.

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, an access point may start a target wake time (TWT) service period (SP). The access point may receive an end of SP (EOSP) indication from a station. The access point may stop the TWT SP before a scheduled end of the TWT SP based on receiving the EOSP indication. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure relate to determining a signaling field modulation and coding scheme (MCS) value for communicating information in a signaling field of a frame to a plurality of user devices. Certain aspects of the present disclosure provide a method for wireless communications by an access point (AP). The method includes determining a signaling field modulation and coding scheme (MCS) value for communicating information in a signaling field of a frame to a plurality of user devices based on one or more data MCS values for communicating payload data of the frame to the plurality of user devices. The method further includes transmitting the frame to the plurality of user devices using the determined signaling field MCS value for the signaling field.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

Abstract: Embodiments of systems and methods for reporting a delay for network segments in an end-to-end communication path may include determining an end-to-end delay measurement of a communication path spanning a first communication network and a second communication network, and transmitting a message including delay information based on the determined end-to-end delay measurement to a network element of the first communication network, wherein the message is configured to enable the network element of the first communication network to configure the first communication network to provide sufficient Quality of Service (QoS) to support an end-to-end QoS requirement based on the delay information.

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, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

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.
