DAA concept with uplink detection: frequency domain quiet periods

A system for detecting a victim wireless device, comprising:

• an interface configured to obtain a set of wireless bands and a set of time periods, wherein during a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data;
• and
• a signal processor which is configured during each of the time periods in the set of time periods to:
• receive a signal, if any;
• and
• in the event a signal is received, record the subset of vacant wireless bands corresponding to that time period;
• and
• after the set of time periods ends, determine whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.

A computer program product for detecting a victim wireless device, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:

• obtaining a set of wireless bands and a set of time periods, wherein during a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data;
• during each of the time periods in the set of time periods:
• receiving a signal, if any;
• and
• in the event a signal is received, recording the subset of vacant wireless bands corresponding to that time period;
• and
• after the set of time periods ends, determining whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.
