Abstract

In a method implemented in a first communication device, a control frame having a bandwidth is generated. The control frame is transmitted via a first composite communication channel, wherein the first composite communication channel comprises a plurality of communication channels. A bandwidth of a response frame, received from a second communication device in response to transmitting the control frame, is determined. A second composite communication channel based on the bandwidth of the response frame is determined, wherein the second composite communication channel comprises at least one communication channel from the plurality of communication channels. One or more data frames are transmitted to the second communication device via the second composite communication channel.
