Claim 4:
5. A method of managing a power state of a wireless station (STA) for cooperative multi-band operation between the STA and a wireless access point (AP) for a wireless network, the method comprising:
performing a wireless transmission to transmit data from the STA to the AP over a first band;
receiving a QoS Null frame transmitted from the STA to the AP using the first band, wherein the STA and the AP are in wireless communication using the first band and a second band, and wherein the QoS Null frame triggers a service period (SP) for the first band and the second band;
pausing the first wireless transmission on the first band and updating a power management mode of the STA for the first band according to a subfield of a frame received by the STA from the AP; and
updating a power management mode of the STA for the second band according to a first subfield of the QoS Null frame received from the STA indicating that additional data is buffered on the second band, wherein the second 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 band.
