10. The electronic device of claim 8 , wherein the processor is configured to set a scan schedule of the receiver based at least on a traffic schedule associated with the data.

11. The electronic device of claim 10 , wherein the receiver is in an awake state when the transceiver is in the awake state.

12. The electronic device of claim 8 , wherein the processor is configured to set a scan schedule of the receiver based at least on a power save schedule of the transceiver.

13. The electronic device of claim 1 , further comprising:

an auxiliary receiver-only radio configured to operate on a frequency associated with the backup link, wherein the transceiver is configured to operate on a frequency associated with the primary link.

14. The electronic device of claim 13 , wherein:

the processor is configured to receive the data on the primary link, from the second electronic device, using the transceiver;

the auxiliary receiver-only radio is in a listening mode prior to the reception of the notification frame on the backup link, from the second electronic device, of the notification frame, and

the processor is configured to transition a radio resource from the transceiver on the primary link to the auxiliary receiver-only radio, upon the reception of the notification frame on the backup link, and to subsequently receive the additional data on the backup link, using the auxiliary receiver-only radio.

15. A method, comprising:

receiving, at a first electronic device, a message from a second electronic device, wherein the message comprises information associated with a backup link of a wireless network;

in response to receiving the message, transmitting, by the first electronic device to the second electronic device, a second message indicating that the first electronic device supports using multiple links and indicating whether the first electronic device supports using the backup link indicated in the message from the second electronic device;

receiving, at the first electronic device and from the second electronic device, data associated with traffic on a primary link of the wireless network; and

in response to a quality of the primary link being below a threshold,

receiving additional data associated with the traffic from the second electronic device on the backup link; or

receiving a notification frame from the second electronic device on the backup link, wherein the notification frame comprises at least one of a notification that the quality of the primary link is below the threshold or information associated with a communication link to be used for communicating the additional data.

16. The method of claim 15 , wherein the first electronic device comprises a first transceiver configured to operate on a frequency associated with the primary link and a second transceiver configured to operate on a frequency associated with the backup link, the method further comprising:

setting a power save schedule of the second transceiver based at least on a traffic schedule associated with the data of the traffic; or
