  • Patent number: 12375322
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify channel responses between antenna elements of antenna arrays of the wireless device and user equipments (UEs) at geographic locations within a coverage area of the wireless device. For example, the wireless device may identify the channel responses based on reference signal transmissions between the UEs and the wireless device. The wireless device may process the channel responses to identify one or more directional power peaks associated with the reference signal transmissions. The wireless device may, based on the one or more directional power peaks, detect phase error values, amplitude error values, or both common to the channel responses. The wireless device may adjust the signal communicated via at least a subset of the antenna elements based on the phase error values, the amplitude error values, or both and communicate with one or more of the UEs.

  • Publication number: 20250233786
    Abstract: A method for wireless communication at a UE and related apparatus are provided. In the method, the UE obtains a first wideband signal having a continuous wideband bandwidth, and separates the first wideband signal into multiple narrowband segments. The multiple narrowband segments each have a narrowband bandwidth less than the continuous wideband bandwidth and different frequency shifts. The UE further performs multiple FFT operations on the multiple narrowband segments to obtain a set of processed segments respectively corresponding to the multiple narrowband segments, and aggregates the set of processed segments to obtain a second wideband signal.
