  • Publication number: 20230016476
    Abstract: An apparatus includes memory and processing circuitry coupled to the memory. The processing circuitry is to decode a client-to-client (C2C) enabling signal received from an access point (AP). The C2C enabling signal indicates the AP is configured for Low Power Indoor (LPI) communication at an LPI signal power level. The signal power of the C2C enabling signal received from the AP is determined. Bluetooth (BT) circuitry of the apparatus is configured for BT communication with a wireless device at the LPI signal power level when the signal power of the C2C enabling signal is above a signal power threshold. The BT circuitry is configured to perform a handshake exchange with the wireless device to initiate the BT communication at the LPI signal power level.

  • Patent number: 11558750
    Abstract: This disclosure describes systems, methods, and devices related to security for multi-link operation. A device may determine a multi-link communication with a first multi-link device comprising two or more links associated with two or more station devices (STAs) included in the first multi-link device. The device may determine a first medium access control (MAC) address associated with a first link of the two or more links. The device may determine a second MAC address associated with a second link of the two or more links. The device may generate one or more pairwise security keys to be used in the multi-link communication on the two or more links. The device may cause to send a frame to the first multi-link device using at least one combination of the one or more pairwise security keys.

  • Publication number: 20220394818
    Abstract: An access point (AP) configured for wireless local area network (WLAN) sensing is configured to encode a trigger frame (TF) for transmission. The trigger frame allocates resource units (RUs) for receiving high-efficiency (HE) trigger-based (TB) physical-layer protocol data units (PPDUs) (HE TB PPDUs) from a plurality of client devices (non-AP STAs). The trigger frame may solicit each of the client devices to transmit an HE TB PPDU in accordance with an UL OFDMA technique or an UL MU-MIMO technique. The AP may decode the HE TB PPDUs received from the client devices and may estimate channel state information (CSI) for a radio link associated with each of the client devices based on an HE-LTF of an associated one of the HE-TB PPDUs received from one of the client devices. In accordance with these embodiments, the AP may process changes in the CSI of the radio links over time for a WLAN sensing application.

  • Patent number: 11516757
    Abstract: Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.
