Method and apparatus for adapting multi-band ultra-wideband signaling to interference sources

A multi-frequency band 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 decide to discontinue use of the respective sub-band;
• the interference compensator configured to determine that subsequent signaling is to be transmitted by a transmitting device in any sub-band except the respective sub-band of the plurality of wideband frequency sub-bands.

A method of communicating channel state information to a transmitting device, the method comprising:

• obtaining channel configuration information, the channel configuration information indicating that a respective sub-band of a plurality of wideband frequency sub-bands includes an interfering signal having signal energy in a portion of a respective sub-band, wherein signaling occurs over the plurality of wideband frequency sub-bands between a transmitting device and a receiving device, wherein each wideband frequency sub-band has 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;
• transmitting a first signal in the respective sub-band including the interfering signal during a first symbol period to the transmitting device;
• transmitting a second signal in the respective sub-band including the interfering signal during a second symbol period to the transmitting device;
• and
• transmitting a third signal in an available sub-band not presently being used for the signaling during the second symbol period to the transmitting device;
• wherein the transmitting device is able to determine which sub-bands of the plurality of wideband frequency sub-bands to transmit the subsequent signaling in, based upon receipt of the first signal, the second signal and the third signal.
