  • 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.
