Communications for frequency modulated continuous wave signals

Abstract

Some examples of the techniques described herein may utilize a frequency modulated continuous wave (FMCW) for one or more procedures. An FMCW may be signal or waveform with a frequency that increases or decreases approximately linearly with time. In some approaches, a first wireless device may transmit an FMCW to a second wireless device. The second wireless device may receive and process the FMCW to perform one or more procedures. For instance, the received FMCW signal may be mixed to generate a beat signal (e.g., narrowband beat signal). The beat signal may be provided to an analog-to-digital converter (ADC). The beat frequency may be utilized for channel quality estimation, beam management, sensing, or positioning procedures. For instance, each beat signal frequency may map to a specific target reflection for a sensing procedure. Processing the FMCW may provide one or more improvements.
