摘要： A method is disclosed for a multi-zone interference correction processing for a rapid thermal processing (RTP) system. This processing allows for improved calibration/tuning of RTP systems by accounting for zone coupling. The disclosed method includes establishing baseline characteristic data and zone characteristic data, and then using the baseline and zone characteristic data to determine lamp-control parameters, such as temperature offset values, for temperature sensors of the RTP system. The baseline characteristic data includes information regarding baseline heating uniformity of an RTP system. The zone characteristic data is collected for a plurality of heating zones within the heating chamber of the RTP system, each zone being associated with a respective temperature probe. The zone characteristic data is collected based on controlled temperature sensor variations. The lamp-control parameters for temperature probes of the RTP system are then calculated based on the baseline characteristic data and the zone characteristic data.

摘要： For example, a first STA may be configured to set link ID information in a link ID field to identify one or more first wireless communication links for a sensing measurement session; and to transmit a wireless sensing measurement frame over a second wireless communication link. For example, the wireless sensing measurement frame may include the link ID field, and one or more sensing measurement parameters to configure the sensing measurement session over the one or more first wireless communication links. For example, a second STA may be configured to process the link ID information; to process the wireless sensing measurement frame to identify the one or more sensing measurement parameters to configure the sensing measurement session over the one or more first wireless communication links; and to establish the sensing measurement session over a link of the one or more first wireless communication links.

摘要： A non-access point station (STA) configured for performing wireless local area network (WLAN) sensing may be configured to update its time-synchronization function (TSF) based on partial TSF information when a sensing poll trigger frame (TF) and the sensing sounding TF are received in a same sensing measurement instance when the sensing sounding TF includes a special user information field containing the partial TSF information.

摘要： An access point station (AP) configured for wireless local area network (WLAN) sensing may be configured to perform a sensing measurement setup with a non-AP station (non-AP STA). The sensing measurement setup may comprise an exchange of sensing measurement request and response frames to establish sensing measurement parameters for one or more sensing measurement instances including trigger-based and non-trigger based sensing measurement instances. The AP may perform sensing measurements with the non-AP STA by transmitting and/or receiving one or more null-data packets (NDPs) for a sensing measurement instance. The NDPs may be configured in accordance with the sensing measurement parameters. For performing a non-trigger based sensing measurement instance when the AP is operating a sensing responder and when reporting was indicated in a sensing measurement setup request frame received from the non-AP STA, the AP may encode a sensing measurement report for transmission to the non-AP STA.

摘要： This disclosure describes systems, methods, and devices related to responder-to-responder Wi-Fi sensing between station devices. A device may cause to send, during a trigger frame sounding phase of a responder-to-responder Wi-Fi sensing, a sensing responder-to-responder sounding trigger frame to the first station device and the second station device, the sensing responder-to-responder sounding trigger frame associated with causing the first station device to send a responder-to-responder null data packet (NDP) to the second station device; cause to send, during a reporting phase of the responder-to-responder Wi-Fi sensing, a sensing report trigger frame to the second station device; and identify, during the reporting phase, a sensing measurement report from the second station device based on the sensing report trigger frame, wherein the sensing measurement report is indicative of measurements of the responder-to-responder NDP.

摘要： This disclosure describes systems, methods, and devices related to peer-to-peer (P2P) Wi-Fi sensing. A device may generate a request to perform P2P Wi-Fi sensing operations with a second non-AP STA; send the request to an AP to which the non-AP STA is associated; identify a response received from the AP, the response indicating that the non-AP STA is a sensing receiver for the P2P Wi-Fi sensing operations; identify a trigger frame received from the AP, the trigger frame associated with the P2P Wi-Fi sensing operations; identify a sensing physical layer (PHY) protocol data unit (PPDU) received from the second non-AP STA, the sensing PPDU associated with the P2P Wi-Fi sensing operations and including an indication that the second non-AP STA sent the sensing PPDU; and determine channel state information based on the sensing PPDU, the channel state information indicative of motion of people or objects.

摘要： 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.

摘要： This disclosure describes systems, methods, and devices related to multi-AP resource sharing. A device may participate in a set of coordinated access points (APs) for coordinating a sharing of one or more resources. The device may evaluate whether there is data to be transmitted to at least one associated station device. The device may, based on the evaluation, perform an action associated with acquiring a first transmit opportunity (TXOP) to be shared with one or more candidate APs of the set of coordinated APs.
