Abstract: This disclosure provides methods, devices and systems for using a variable authentication identifier (AID) for access point (AP) privacy. For example, instead of a persistent SSID, an AID is used by a station (STA) to authenticate the AP before connecting to the AP. The AP is associated with a service set, and the STA has stored a secret token associated with the service set. Before connecting to the AP, a broadcasted probe request from the STA includes no identifying information other than the token. The AP generates the AID from the token and provides the AID in a probe response. The STA is able to identify the AP as being associated with a service set and connect to the AP using the token and AID without the token and the AID being used by another device not associated with the service set to identify the AP.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). In some aspects, a first WLAN device may transmit a first HARQ frame to a second WLAN device. The first WLAN device may determine whether a first feedback message received from the second WLAN device includes HARQ acknowledgement information or non-HARQ acknowledgment information. The first feedback message may be a HARQ Block Acknowledgement (H-BA) message having a multi-station Block ACK (M-BA) frame format that includes HARQ acknowledgment information. The first WLAN device may transmit a second HARQ frame to the second WLAN device in response to determining the first feedback message includes the HARQ acknowledgment information. The first WLAN device may transmit a non-HARQ frame in response to determining the first feedback message includes non-HARQ acknowledgement information.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for advertising operating channels that are being operated in an unlicensed frequency band. One or more access points (APs) may transmit discovery information on a dedicated discovery channel for the unlicensed frequency band. The discovery information may indicate at least one operating channel that is being used by an AP for providing wireless access. The discovery information also may include other information useful for a station (STA) to discover APs, operating channels, and operating parameters. The STA may monitor the dedicated discovery channel to obtain the discovery information without conducting an active scanning or passive scanning procedure.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used for channel puncturing. A wireless station (STA) may receive an indication of a first puncturing pattern to be used for transmitting or receiving data over a wireless channel, where the first puncturing pattern is defined by a first wireless communication protocol release and the STA is configured to operate according to a second wireless communication protocol release. The STA may select, from a set of puncturing patterns defined by the second wireless communication protocol release, a second puncturing pattern that includes one or more non-punctured subchannels that are subsets of one or more corresponding non-punctured subchannels of the first puncturing pattern. The STA may use the second puncturing pattern to transmit or receive one or more packets over the wireless channel.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QoS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

Abstract: Certain aspects of the present disclosure provide an apparatus for wireless communication. The apparatus generally includes a processing system configured to generate a message comprising coordination information, wherein the apparatus is associated with a first AP, the message to be used for coordinated communications by the first AP and a second AP, wherein the first AP and the second AP are associated with different basic service sets (BSSs), and an interface configured to output the message for transmission during a networking coordination window of a networking cluster.

Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for one or more wireless devices to gain access to a wireless channel of a radio frequency spectrum band. In some aspects, a recurring coordinated medium interval is defined in the time domain and associated with the wireless channel. The coordinated medium interval includes a first time period, which may be referred to as a common reservation window, and a second time period, which may be referred to as a scheduled medium access window. During the first time period, access points (APs) attempting to gain access to the wireless channel may transmit reservation signals to reserve one or more scheduled service periods within the second time period of the same coordinated medium interval. The scheduled service periods reserved by an individual AP may be used for UL/DL communications between that AP and its associated stations (STAs).

Abstract: Methods and systems for accessing networks prohibit uncontrolled communications over a designated network. In some aspects, a method of controlling network access is disclosed. The method comprises transmitting, by a first access point, a first beacon over a first network to a station, the first beacon including information allowing the station to associate with the first access point. The method also comprises receiving a probe request at the first access point over the first network from the station, the probe request including a request for rules for associating with a second network. The method additional comprises generating a probe response to include the rules regarding associating with the second network, wherein the rules do not permit uncontrolled communications over the second network. The method further comprises transmitting the probe response from the first access point to the station over the first network.
