Method and apparatus for channel management in cognitive radio system supporting multiple channels
First Claim
Patent Images
1. A channel management method in a Cognitive Radio (CR) system supporting multiple channels, the method comprising:
- generating a candidate channel set from an available channel list;
configuring a backup channel set by combining at least one candidate channel;
determining a priority for each element of the backup channel, according to a criterion for at least one of maximum frequency efficiency, minimum channel interference and maximum channel spacing;
sorting channel combinations of the backup channel set according to the priority; and
updating the backup channel set when a channel change event occurs,wherein the backup channel set is configured by a multi-channel scheme comprising a channel bonding scheme, a Scalable Orthogonal Frequency Division Multiple Access (OFDMA) scheme, or a channel aggregation scheme that supports the multiple channels.

Abstract
A method and apparatus for channel management in a Cognitive Radio (CR) system supporting multiple channels are provided. The method includes generating a candidate channel set from an available channel list, configuring a backup channel set by combining at least one candidate channel, and updating the backup channel set when a channel change event occurs. Accordingly, the multiple channels can be effectively used in CR communication.
