Abstract: Power management operations are performed by devices communicating using multiple bands simultaneously where a first wireless band can be used to send and receive power management control frames for use on a second wireless band of a wireless network. In this way, a device that is in a sleep or dose power management state on a first band can be instructed to enter an awake power management state on the first band based on a communication received over a second band that is currently active and receiving data. Embodiments of the present invention enable power to be conserved when a band is not currently being used, or when there is no more data available (buffered) for a specific band.
