Radar detection for adjacent segments in wireless communications

摘要

A method and apparatus are disclosed for searching for a radar signal within signals received by a wireless device. The wireless device may receive signals within a first frequency segment and a second frequency segment, which is adjacent to the first frequency segment. The wireless device may search for the radar signal within the first frequency segment or the second frequency segment based, at least in part, on Fast Fourier Transform bins associated with the received signals.

主权项

1. A method of searching for a radar signal by a wireless device, the method comprising:
receiving signals, at the wireless device, within a first frequency segment and a second frequency segment, wherein the second frequency segment is adjacent to the first frequency segment; determining a first set of Fast Fourier Transform (FFT) bins associated with the first frequency segment; determining a second set of FFT bins associated with the second frequency segment; searching the first frequency segment for the radar signal based, at least in part, on the first set of FFT bins and the second set of FFT bins; determining a third set of FFT bins associated with the first frequency segment; and searching the second frequency segment for the radar signal based, at least in part, on a determination that the third set of FFT bins is within a threshold amount of a segment boundary between the first frequency segment and the second frequency segment.
