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.
