Abstract
In a wireless communication network that operates according to a communication protocol that permits transmissions via multiple channels corresponding to multiple different frequency bandwidths, a communication device receives a packet via a first communication channel that spans a first frequency bandwidth. The communication device determines a second communication channel for transmitting an acknowledgment packet, the second communication channel spanning a second frequency bandwidth that is less than the first frequency bandwidth, the acknowledgment packet responsive to receiving the packet. The communication device transmits the acknowledgment packet via the second communication channel.
