Abstract
In a method of determining channel availability in a wireless communication network utilizing at least first and second sub-channels, a first signal is received via a first channel. The first signal includes first access control information indicating expected utilization of the first channel. The first channel includes the first sub-channel. A first sub-channel availability indicator is updated based on the first access control information. The first sub-channel availability indicator indicates expected utilization of the first sub-channel. A second signal is received via a second channel. The second signal includes second access control information indicating expected utilization of the second channel. The second channel includes the second sub-channel. A second sub-channel availability indicator is updated based on the second access control information. The second sub-channel availability indicator indicates expected utilization of the second sub-channel. A transmission channel is determined based on the first and second sub-channel availability indicators.
