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.

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, devices, apparatus and methods, including computer programs encoded on storage media, for sharing a transmission opportunity (TXOP) of a wireless channel. A first wireless local area network (WLAN) device can win a contention-based procedure to become an owner of the TXOP and determine to use the TXOP as a multi-device transmission opportunity (mTXOP). Although the first WLAN device is the owner of the mTXOP, the first WLAN device may allocate resources from the mTXOP to share with other WLAN devices. During a first portion of the mTXOP, the first WLAN device allocate subordinate transmission opportunities (sub-TXOPs) for use by other WLAN devices during a second portion of the mTXOP. The allocation of sub-TXOPs may be prepared based on fairness considerations, latency considerations, or both. In some implementations, a sub-TXOP may be allocated for a non-WLAN device, such as a wireless wide area network (WWAN) apparatus.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS). In one aspect, an apparatus may establish a first communication link with a first station (STA) of the first BSS using a first frequency band. The apparatus may determine a first link profile for a second communication link by customizing one or more management elements of management information associated with the first communication link. The apparatus may configure a first non-inheritance element of the first link profile associated with the second communication link to indicate usage of at least one management element of the management information by the second communication link is disabled. The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.

Abstract: This disclosure provides methods, devices, and techniques to indicate operations by extremely high throughput (EHT) devices on an operating bandwidth, including devices in a basic service set (BSS) supporting the use of a 320 MHz channel. In some aspects, the supported functionality may include extensions to flexibility and support rules, structures, and signaling using legacy fields, frames, and features. In addition, the supported functionality may include channel sensing and reporting, such as per-channel network allocation vectors (NAVs) for the sub-channels of the operating bandwidth. A device may identify an operating mode for an operating bandwidth and determine a value for a bandwidth query report (BQR) or a target wake time (TWT) element. The device may check multiple NAVs for sub-channels of the operating bandwidth. The operating bandwidth may span concurrent operations on traditional Wi-Fi frequency bands including the 2.4 and 5 GHz bands as well as the 6 GHz band.

Abstract: Techniques for improved spatial reuse for wireless local area network (WLAN) networks are described. An access point (AP) may win a contention to a wireless medium and obtain a transmission opportunity (TXOP). The AP may perform a procedure to identify a group of un-managed APs for participation in spatial reuse opportunities for synchronous transmission over the TXOP. The AP may perform the procedure using over-the-air signaling. The AP may transmit a spatial reuse (SR) poll frame to one or more un-managed APs of the network, either sequentially or as part of a multiple-AP procedure. The AP may receive an SR response frame, or directly measure potential interference of a station (STA) serviced by one or more un-managed APs, and select a group of APs for coordinated reuse over the TXOP. The AP may select the group of APs based on one or more criteria for coordinated reuse.

Abstract: Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, selected stations may be triggered to communicate with respective access points.
