Abstract
In a method of determining an available channel bandwidth in a communication system, wherein the communication system utilizes i) a set of component channels for transmitting data streams and ii) a set of access control channels, and wherein each of at least some of the access control channels partially overlaps, in frequency, at least one of the component channels, whether a primary channel of the access control channels is idle is determined. The primary channel partially overlaps, in frequency, at least a first one of the component channels. That a composite channel includes one or more of the component channels is determined based at least on a determination of whether the primary channel is idle. A signal is caused to be transmitted via the composite channel after determining that the composite channel includes one or more of the component channels.
