Abstract: To address the inefficiency and unfairness issues in channel bonding, a dynamic channel bonding protocol is presented in which a node is allowed to start a transmission as long as a narrow channel is available and gradually increase channel width during transmission whenever a new narrow channel becomes available. The protocol aggregates all available narrow channels as one wide channel, removing the need of setting guard bands between contiguous narrow channels. A challenge in dynamic channel bonding is the communication over uncertain channels. To enable fast spectrum agreement between transmitter and receiver, a partial spectrum correlation method is introduced. When new channels become available, multiple nodes may contend for them. A compound preamble is designed to make collisions detectable in the frequency domain and a parallel bitwise arbitration mechanism is used to quickly resolve the collisions in the time domain.
