Abstract: Embodiments of a STA configured for proximity detection by multiple WLAN link tracking are disclosed herein. In some embodiments, the STA performs WLAN sensing using two or more WLAN links with one or more other STAs to track a channel state of each link and performs motion detection based on the tracked channel state of each WLAN link to detect motion in any of the WLAN links. If motion is detected in at least some of the WLAN links, the STA may perform proximity detection to indicate proximity by combining results of the WLAN sensing for each link to determine whether the motion is proximate to the STA or proximate to one of the other STAs.

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.

Abstract: Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including one or more antennas configured to receive an RF signal and an ADC system. The ADC system includes a 1-bit ADC configured to receive the RF signal, and an ADC controller circuitry configured to measure a number of positive samples in the received RF signal for a plurality of thresholds of the 1-bit ADC, estimate receive signal power associated with the received RF signal based on the measured number of positive samples, determine a direct current(DC) offset in the received RF signal using the estimated received signal power, and adjust the received RF signal based on the determined DC offset.
