摘要： Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of a responder station (RSTA) is disclosed, the apparatus comprising processing circuitry configured to decode a null data packet (NDP) announce (NDPA) frame from an initiator station (ISTA), the NDPA frame comprising an indication of a temporary key and an identification of the RSTA. The processing circuitry further configured to decode a NDP from the ISTA, the NDP comprising long training fields (LTFs), the NDP received on a channel. The processing circuitry further configured to determine whether the NDP from the ISTA is consistent with the NDP being generated using a temporary key shared between the ISTA and RSTA based on a comparison of the channel estimates. The processing circuitry may be further configured to determine for authentication whether the indication of the temporary key was generated based on the temporary key.

摘要： Embodiments of an access point (AP), station (STA) and method of sounding are generally described herein. The AP may transmit, during a transmission opportunity (TXOP), a trigger frame (TF) to indicate that an STA is to transmit an uplink sounding packet during an uplink sounding period of the TXOP. The AP may attempt to detect the uplink sounding packet during the uplink sounding period. If the uplink sounding packet is not detected during the uplink sounding period, the AP may transmit a recovery packet to cause other STAs to determine a busy condition during the uplink sounding period. If the uplink sounding packet is detected during the uplink sounding period, the AP may determine a channel estimate for the STA based at least partly on the uplink sounding packet.

摘要： Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of an initiator station (ISTA), where the apparatus comprises processing circuitry configured to encode a null data packet announce (NDPA) frame for transmission to a responder station (RSTA), the NDPA frame indicating a sounding sequence number, and encode a first null data packet (NDP) for transmission at a time T1 to the RSTA. The processing circuitry may be further configured to: decode a second NDP, the second NDP received from the RSTA, wherein the second NDP is received at a time T4, and decode a first location measurement report (LMR). The processing circuitry may be further configured to in response to an ISTA-to-RSTA LMR feedback agreement between the RSTA and ISTA indicating the ISTA is to send a second LMR, encode a second LMR.

摘要： This disclosure describes systems, methods, and devices related to secure location measurement sharing. A device may cause to send a first indication associated with a location of the device to a cloud server. The device may cause to send a second indication associated with a ranging information of an access point (AP), wherein the AP is connected to the cloud server. The device may identify an access token received from the cloud server, wherein the access token is associated with providing anonymized AP location information to the AP, and wherein the access token is associated with accessing channel allocation from a channel access database.
