Abstract: A device (e.g., an IoT device) includes a first radio, and a memory device accessible to the first radio. The memory device is configured to store a fingerprinting feature for a specific transmitter device. A second radio and a processor are also included. The process is coupled to the first and second radios. The first radio is configured to extract a fingerprinting feature of a first received wireless signal, determine that the extracted feature matches the fingerprinting feature stored in the storage device, and responsive to the determination that the extracted feature matches the feature stored in the storage device, cause the second radio to transition from a lower power state to a higher power state of operation and continue to receive the incoming signal.

Abstract: A user client device with a single receive (RX) chain, a first antenna and a second antenna, and a processor that causes the user client device to couple the single RX chain to the first antenna to receive a first data packet on a first channel and determine a first channel state information (CSI) tile of the first channel based on one or more fields in the first data packet, decouple the first antenna from the single RX chain and couple the second antenna to the single RX chain to continue receiving the first data packet on a second channel, determine a second CSI tile of the second channel based on one or more of a portion of the first plurality of fields, aggregate the first CSI tile with the second CSI tile, and generate a CSI matrix based on aggregating the first CSI tile with the second CSI tile.

Abstract: Techniques for determining an angle-of-arrival of a wireless transmission are provided, including receiving, with a first antenna, at least a first portion of a wireless transmission, determining when a second portion of the wireless transmission will be received, switching to the second antenna to receive the second portion of the wireless transmission, determining an angle of arrival of the wireless transmission based on the first portion and the second portion of the wireless transmission, and outputting the angle of arrival of the wireless transmission.

Abstract: A wireless station (STA) in a wireless local area network (WLAN) performs a method to avoid media access control (MAC) padding of a physical layer convergence protocol data unit (PPDU) (e.g., a trigger-based (TB) PPDU, etc.). The method can reduce current or power consumption by the STA, which can in turn optimize the STA and, in certain instances, the WLAN as whole. In one example, the method includes the STA receiving a trigger frame from an access point (AP). The trigger frame specifies a length of a PPDU. The method further includes the STA generating a TB PPDU based on the specifications in the trigger frame. In particular, the STA generates a PPDU that has a length that is less than the length specified by the trigger frame. The method also includes the STA transmitting the generated PPDU to the AP.
