Abstract
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. The first frequency segment and the second frequency segment may be non-contiguous. The wireless device may determine energy within the first frequency segment and the second frequency segment and may detect a strong signal event with the first and/or the second frequency segments. In response to detecting the strong signal event, the wireless may search for the radar signal based, at least in part, on the determined energy within the first frequency segment and the second frequency segment and the strong signal event.
Claims30
A method of detecting 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;
- determining energy within the first frequency segment and the second frequency segment based, at least in part, on the received signals;
- detecting a strong signal event based, at least in part, on the received signals;
- and
- searching for the radar signal based, at least in part, on the determined energy and the strong signal event.
A wireless device, comprising:
- a transceiver;
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the wireless device to:
- receive signals, at the wireless device, within a first frequency segment and a second frequency segment;
- determine energy within the first frequency segment and the second frequency segment based, at least in part, on the received signals;
- detect a strong signal event based, at least in part, on the received signals;
- and
- search for a radar signal based, at least in part, on the determined energy and the strong signal event.
A non-transitory computer-readable medium storing instructions that, when executed by a processor of a wireless device, causes the wireless device to:
- receive signals, at the wireless device, within a first frequency segment and a second frequency segment;
- determine energy within the first frequency segment and the second frequency segment based, at least in part, on the received signals;
- detect a strong signal event based, at least in part, on the received signals;
- and
- search for a radar signal based, at least in part, on the determined energy and the strong signal event.
