Channel Discovery and Disconnection in Networks Over White Spaces and Other Portions of the Spectrum
First Claim
1. A method, using electronic processing functionality, for extracting information from spectrum, comprising:
- investigating a plurality of spectrum units in a time domain to identify a characteristic signal;
deriving information based on the characteristic signal to provide derived information; and
governing a communication among at least two nodes based on the derived information.

Abstract
Functionality is described for discovering a channel within an environment in which non-privileged entities have subordinate access rights to spectrum compared to privileged entities. The functionality operates by investigating spectrum units within the spectrum for the presence of the channel. In one case, the functionality operates by investigating the spectrum units in linear succession; in another case, the functionality advances in a staggered fashion over the available spectrum. Functionality is also described for handling disconnection by a node from a channel. The functionality allows the node to convey its disconnection status to other communication participants. In one case, various aspects of the functionality are implemented by performing analysis in the time domain.

9. A computer readable medium for storing computer readable instructions, the computer readable instructions providing a discovery module when executed by one or more processing devices, the computer readable instructions comprising:
-
logic configured to advance to a spectrum unit within the available spectrum; logic configured to determine whether the spectrum unit is at least part of a channel, the channel being said to be discovered if it is determined that the spectrum unit is at least part of the channel; and said logic configured to advance and said logic configured to determine repeating their respective advancing and determining operations until the channel is discovered. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A disconnection management module, comprising:
-
logic configured to detect a presence of a privileged entity operating on a channel that is being used by a first node to communicate with a second node, the first node and the second node being associated with non-privileged entities, the non-privileged entities having subordinate access rights compared to the privileged entity; logic configured to disconnect the first node from the channel; and logic configured to send notification information to a second node that indicates that the first node has disconnected from the channel. - View Dependent Claims (17, 18, 19, 20)
