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; and
updating the backup channel set when a channel change event occurs.wherein the configuring the backup channel by combining at least one candidate channel comprises determining a multi-channel scheme as a channel bonding, a Scalable Orthogonal Frequency Division Multiple Access (OFDMA), or a channel aggregation.

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.
