Abstract
In a method implemented in a communication device an available bandwidth for transmitting one or more data frames is determined, wherein the available bandwidth corresponds to a first composite communication channel comprising a plurality of communication channels. A control frame to indicate a request to transmit via the first composite communication channel is generated, wherein the control frame includes a header, and wherein a portion of the header includes information indicating the bandwidth of the first composite channel. The control frame is transmitted via the first composite communication channel, wherein at least the portion of the header is duplicated in a plurality of bandwidth portions of the first composite communication channel.
