Abstract
In one embodiment, the invention provides a method comprising performing a channel assessment of predefined communications channels, each centered on a particular frequency within a frequency band, the channel assessment comprising determining if interference on each predefined channel is above a predefined energy threshold, wherein the predefined communications channels are visited in a predefined sequence in which those predefined channels in which interference from specific types of interferers known to operate in the frequency band is likely are visited first. The method also comprises disabling those communications channels on which interference above the predefined energy threshold is detected.
Claims21
A method comprising:
- performing a channel assessment of predefined communications channels each centered on a particular frequency within a frequency band, the channel assessment comprising determining if interference on each predefined channel is above a predefined energy threshold, wherein the predefined communications channels are visited in a predefined sequence in which those channels in which interference from specific types of interferers known to operate in the frequency band is likely are visited first;
- and
- disabling those communications channels on which interference above the predefined energy threshold is detected.
A receiver comprising:
- a receiver section to receive signals on predefined communications channels, each centered on a particular frequency within a frequency band;
- a memory to store a predefined sequence in which the receiver section is to be tuned to the predefined communications channels;
- and
- a channel assessment mechanism to perform a channel assessment of the predefined communications channels, the channel assessment comprising determining if interference on each predefined communications channel is above a predefined energy threshold, wherein the predefined communications channels are visited in the predefined sequence.
A system comprising:
- means for performing a channel assessment of predefined communications channels, each centered on a particular frequency within a frequency band, the channel assessment comprising determining if interference on each predefined channel is above a predefined energy threshold, wherein the predefined communications channels are visited in a predefined sequence in which those predefined channels in which interference from specific types of interferers known to operate in the frequency band is likely are visited first;
- and
- means for disabling those communications channels on which interference above the predefined energy threshold is detected.
