Abstract: An example method of ultra-wideband (UWB) sensing performed by a wireless communication device, the method comprising determining a first channel impulse response (CIR) estimation of a first frequency channel based on a radio access technology (RAT) session, wherein the RAT is different from UWB. The method also comprises determining a second CIR estimation of a second frequency channel based on a UWB session and determining a third CIR estimation of the first frequency channel based on determining a phase difference between the third CIR estimation and the first CIR estimation. The method further comprises determining a total CIR estimation for a combined frequency channel comprising the first frequency channel and the second frequency channel based on stitching the first CIR estimation, the second CIR estimation, and the third CIR estimation.

Abstract: This disclosure provides methods, components, devices and systems for adjacent channel interference (ACI) mitigation techniques for ultra-wideband (UWB) systems. Some aspects more specifically relate to ACI mitigation for UWB systems. In some implementations, a wireless communication device may receive control information that identifies a preamble for communications to the wireless communication device in a UWB system. The wireless communication device may receive, via a signal in the UWB system, a data packet that includes the preamble. The wireless communication device may estimate a channel impulse response (CIR) of the signal and determine an interference metric that is based on the estimated CIR. The wireless communication device may process the data packet based on the interference metric.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, related to low power techniques for a BLE device during a scanning state. The BLE device is configured to scan for a preamble of a packet while in a first power mode and detect when a bit of the preamble is received. Upon detecting that the bit of the preamble is received, the BLE device switches from the first power mode to a second power having a higher operating power for the BLE device than the first power mode. The switch in power modes occurs while the preamble is being received or immediately after the preamble is received and before an access address of the packet is received. The BLE device, while in the second power mode, then scans for the access address of the packet.
