Abstract: Wireless dynamic file exchange is provided by, in response to a triggering network condition occurring, initiating an exchange of a parameter file including non-layer two content via a 802.11 message, such as a Generic Advertisement Service (GAS) message between an access point (AP) and a station (STA) connected to the AP; and in response to determining that the exchange was unsuccessful, terminating a connection between the AP and the STA. The parameter file may be sent over several messages and update the parameters for a new session or an existing session. Devices that do not conform to the updated parameters may be disassociated from the AP and re-connect to receive and implement the updated parameters.

Abstract: Techniques for facilitating client mobility without performing re-association are described. An example technique includes receiving, from a first access point (AP), an indication of at least one second AP neighboring the first AP. A multi-link association is performed. The multi-link association includes establishing a first link with the first AP and pre-establishing a second link with the second AP. After performing the multi-link association, the first AP is communicated with at a first instance in time via the first link.

Abstract: A method includes determining whether a first access point of a plurality of access points and a second access point of the plurality of access points should communicate simultaneously over a shared channel in a first network and in response to determining that one of the plurality of access points won contention of a transmission opportunity for the shared channel, dividing the transmission opportunity into a plurality of time slots. The method also includes scheduling transmissions of the first and second access points into the plurality of time slots according to the determination whether the first and second access points should communicate simultaneously over the shared channel and communicating, to the second access point and over a wired network or a second network different from the first network, an indication of whether the second access point should communicate during a first time slot of the plurality of time slots.

Abstract: Techniques for determining a range between a wireless station (STA) and a wireless access point (AP) using channel state information are described. An AP determines channel state information corresponding to an STA. The AP determines, based on the channel state information, one or more fine timing measurement (FTM) parameters. A plurality of FTM messages are transmitted between the AP and the STA, based on the one or more FTM parameters. The STA is configured to determine an estimated range to the AP based on the plurality of FTM messages.

Abstract: Techniques for intelligent multi-link operation (MLO) mode selection are provided. One or more metrics for wireless communication in a wireless network is collected. A set of multi-link operation (MLO) modes available for the wireless communication between a station multi-link device (STA MLD) and a first access point multi-link device (AP MLD) in the wireless network is determined. A first MLO mode of the set of MLO modes is selected based on the one or more collected metrics. The wireless communication is performed using the selected first MLO mode.

Abstract: A signaling mechanism is provided that includes a restricted random access resource unit (XRA RU) that restricts uplink random access, such as by using Uplink Orthogonal frequency-division multiple access-based Random Access (UORA), to a subset of a plurality of stations that are associated with an Access Point (AP). In one aspect, an AP allocates a resource unit as an XRA RU that restricts uplink random access to a subset of a plurality of stations (STAs) that are associated with the AP. The AP transmits an uplink trigger that includes the XRA RU. The AP restricts use of the XRA RU to the subset of the plurality of STAs. In this way, STAs of the subset can attempt contention-based random access with the XRA RU while other STAs are prevented from attempting random access with the XRA RU.

Abstract: A preemption service in a wireless network is described. The preemption network increases the reliability of preemption traffic to be quickly delivered over the wireless network. The active preemption service in wireless networks causes the devices in a wireless network to enter a low transmit power state where every device transmits at a power lower than a high or maximum transmission power. Preemption traffic is transmitted from authorized devices at a high or maximum power, over the lower power transmissions, in order to provide an increased guarantee that the preemption traffic will arrive at the intended recipient.

Abstract: Techniques for improved mobility support in wireless networks are provided. A first beacon from a first wireless AP is received, where the first beacon comprises a network identifier (NID) and a service set identifier (SSID). A client device associates to the first wireless AP. Based on the NID, a set of services supported by the first wireless AP are determined. A second beacon is received from a second wireless AP, where the second beacon comprises the first NID, and the client device associates to the second wireless AP based on determining, based on the NID, that the second wireless AP supports the set of services.

Abstract: Techniques for improved peer-to-peer communication are provided. A wireless access point (AP) may initiate peer-to-peer communication between multilink peer-to-peer devices by sending a trigger frame addressed to the peer-to-peer devices to hand over a transmission opportunity (TXOP). The trigger frame is sent based on the AP's knowledge of the availability of the peer-to-peer devices for peer-to-peer communication. The trigger frame indicates a link to be used for the peer-to-peer communication. In response to receiving the trigger frame one or more of the peer-to-peer devices acknowledge the trigger frame, tune to the assigned link, and use the remaining portion of the TXOP for peer-to-peer communication.
