Method and apparatus for adapting signaling to maximize the efficiency of spectrum usage for multi-band systems in the presence of interference
First Claim
1. A method of operation in a multi-frequency band wideband system in the presence of an interference, the method comprising:
- receiving signaling in a plurality of wideband frequency sub-bands, each wideband frequency sub-band having a different center frequency, wherein a bandwidth of each wideband frequency sub-band is at least 2 percent of a center frequency of the wideband frequency sub-band;
detecting an interfering signal having signal energy in a portion of a respective sub-band of the wideband frequency sub-bands;
modifying at least one of a center frequency and a bandwidth of the respective sub-band in order to operate in the presence of the interfering signal; and
instructing a transmitting device transmitting the signaling to transmit subsequent signaling accounting for the modification of the center frequency of the respective sub-band.

21. A multi-frequency band wideband receiver for operating in the presence of an interference, the receiver comprising:
-
a signal detector configured to receive signaling in a plurality of wideband frequency sub-bands, each wideband frequency sub-band having a different center frequency, wherein a bandwidth of each wideband frequency sub-band is at least 2 percent of a center frequency of the wideband frequency sub-band;
an interference detector coupled to the signal detector and configured to detect an interfering signal having signal energy in a portion of a respective sub-band of the wideband frequency sub-bands; and
an interference compensator coupled to the interference detector and configured to modify at least one of a center frequency and a bandwidth of the respective sub-band in order to operate in the presence of the interfering signal;
the interference compensator configured to determine that subsequent signaling to be transmitted from a transmitting device is to be transmitted to account for the modification of the center frequency of the respective sub-band. - View Dependent Claims (22, 23)
