Abstract: This disclosure describes systems, methods, and devices related to enhanced feedback for secure mode wireless communications. A device may send a first null data packet (NDP) to a second device, and identify a second NDP received from the second device. The device may identify a location measurement report (LMR) received from the second device, the LMR including a first channel response indicative of a first arrival time of the first NDP at the second device and a first phase shift associated with the first NDP. The device may generate a second channel response indicative of a second arrival time of the second NDP at the device and a second phase shift associated with the second NDP. The device may determine that the first channel response does not match the second channel response, and may identify an attempted attack.

Abstract: This disclosure describes systems, methods, and devices related to null data packet (NDP) frame format. A device may cause to send a null data packet announcement (NDPA) frame to a responding station device (RSTA). The device may cause to send a first sounding NDP frame comprising one or more fields formatted to support 2.4 gigahertz (GHz) and 5 GHz bands in a non-trigger-based ranging measurement with the RSTA. The device may identify after a passage of a short inter-frame space (SIFS) time a second NDP frame received from the RSTA. The device may identify a location measurement report frame from the RSTA.

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) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable to operate as a controlling AP of a multi-AP group. The controlling AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The controlling AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.
