Abstract: Systems and methods for wireless communication are disclosed. In one aspect an access point transmits a message to a first device and a second device on a first channel, the message sufficient to inform the first device to camp on a first channel during a time slot and the message sufficient to inform the second device to camp on a second channel during the time slot. The access point further determines whether the first channel is busy during the time slot. If the first channel is determined to not be busy during the time slot, the access point communicates with the first device on the first channel during the time slot. If the first channel is determined to be busy during the time slot, the access point communicates with the second device on the second channel during the time slot.
