Classification: CPC H  Y | IPC H

Claim 6:
7. A wireless access point (AP) for performing cooperative multi-band operation with a wireless station (STA) in a wireless network, the AP comprising:
a first transceiver configured to communicate over a first wireless band;
a second transceiver configured to communicate over a second wireless band, wherein the first transceiver and the second transceiver are operable to communicate simultaneously;
a cooperative management unit configured to exchange data with the first transceiver and the second transceiver for managing simultaneous communication of the first transceiver and the second transceiver; and
a processor operable to:
receive a QoS Null frame transmitted from the STA using the first wireless band, and wherein the QoS Null frame triggers a service period (SP) for the first wireless band and the second wireless band;
pause the first wireless transmission on the first wireless band and updating a power management mode of the STA for the first wireless band according to a subfield of a frame received by the STA from the AP; and
update a power management mode of the STA for the second wireless band according to a first subfield of the QoS Null frame received from the STA indicating that additional data is buffered on the second wireless band, wherein the second wireless band is identified by a band information subfield of the QoS Null frame, wherein the QoS Null frame further comprises a second subfield indicating additional data is buffered on the second wireless band.
