1. A method, comprising:
- receiving, by an access point (AP), an interval value from a station (STA), wherein the interval value corresponds to a frequency with which the STA listens to said AP;
commanding, by the AP, said STA to refrain from transmitting data to said AP until a period expires, wherein said commanding comprises the AP setting a duration of said period to correspond to said interval value; and
transferring, by the AP, data to said STA after said period expires.

Abstract
A method that comprises receiving, by an access point (AP), an interval value from a station (STA). The interval value corresponds to a frequency with which the STA listens to the AP. The method also comprises commanding, by the AP, the STA to refrain from transmitting data to the AP until a period expires. The commanding comprises the AP setting a duration of the period to correspond to the interval value. The method further comprises transferring, by the AP, data to the STA after the period expires.

8. A method, comprising:
-
a station (STA) transmitting an interval value to an access point (AP), wherein the interval value corresponds to a frequency with which the STA listens to said AP, and wherein said interval value is less than additional interval values of other STAs with which the AP communicates; as a result of receiving a command from the AP, the STA refraining from transmitting data to the AP until a period expires and the STA powering down at least some data transmission circuitry during said period, a duration of said period corresponds to said interval value; and receiving, by the STA, data from the AP after said period expires. - View Dependent Claims (9, 10, 11)

12. A system, comprising:
-
a transceiver; and a processor coupled to said transceiver that receives an interval value from a station (STA), said interval value corresponds to a timing with which the STA listens to the transceiver; wherein the processor commands the STA to cease data transmissions to the transceiver until a period expires, a duration of the period associates with said interval value; wherein the transceiver does not transmit data to the STA during said period; wherein, after said period expires, the transceiver is reactivated and transmits data to said STA. - View Dependent Claims (13, 14, 15, 16)

17. A system, comprising:
-
a transceiver; and a processor coupled to the transceiver; wherein the transceiver transmits an interval value to an access point (AP), the interval value corresponds to a timing with which the processor listens for signals from the AP; wherein the processor does not transmit data to the AP until a period expires and the transceiver is powered down during said period, the period has a duration that corresponds to the interval value; wherein the transceiver reactivates and sends a signal to the AP after said period expires. - View Dependent Claims (18, 19, 20)
