Abstract: Methods, apparatuses, and computer readable media for channel state information for multiple access points are disclosed. Channel station information (CSI) may be coordinated for multiple access points (APs) where one AP may act as a master AP with other AP acting as slave APs. The channel station information may be based on information from null data packets received by stations from multiple-APs, which may enable a multi-AP coordinated beamforming (CBF) to be determined based on the received first CSI reports. New frame formats are disclosed that include fields for including APs. Overlapping basic service set (OBSS) stations may respond to APs that are not within their BSS. Some embodiments relate to passive range finding in a multi-AP sounding where location configuration information (LCI) changes for one of the APs.

Abstract: An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.

Abstract: Embodiments of a multi-link access point (AP) device, station (STA) and method of communication are generally described herein. The multi-link AP device may comprise multiple APs. The multi-link AP device may encode a frame for transmission by one of the APs of the multi-link AP device. The multi-link AP device may encode the frame to include signaling to enable multi-link discovery of the APs of the multi-link AP device. The multi-link AP device may encode the signaling to include: a reduced neighbor report (RNR) element that identifies the APs of the multi-link AP device, and a multiple AP element. The multiple AP element may be configurable to include: common information for the APs of the multi-link AP device, and per-AP sub-elements that include per-AP information related to the APs of the multi-link AP device.

Abstract: This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.

Abstract: For example, a non Access Point (AP) (non-AP) wireless communication station (STA) and/or an AP STA may be configured to utilize a mechanism configured to support bandwidth signaling for a link between the non-AP STA and an other non-AP STA. For example, an apparatus may include logic and circuitry configured to cause a non-AP STA to set a channel bandwidth field to indicate a maximum channel bandwidth (BW) for the link between the non-AP STA and an other non-AP STA; and to transmit a frame to an AP STA, the frame including an information element including the channel bandwidth field.
