Abstract
A first communication device receives a first data unit from a second communication device via one or more communication channels. The first data unit includes an indication of a first set of one or more sub-channels allocated to the first communication device, and the first data unit is configured to prompt the first communication device to transmit channel availability information as part of a subsequent orthogonal frequency division multiple access (OFDMA) transmission. The first communication device determines channel availability information for the one or more communication channels, and when the first communication device determines that at least one of the communication channels is idle, the first communication device transmits a second data unit to the second communication device in one or more sub-channels allocated to the first communication device as part of the OFDMA transmission, the second data unit including the channel availability information.
