Device setup states for link aggregation in wireless communications
This disclosure describes systems, methods, and devices related to link aggregation between devices. A device may determine a first frequency band and a second frequency band for sending data to a second device in a multiband link aggregation session. The device may cause to send, in an initial state, a setup request frame to the second device for establishing the multiband link aggregation session. The device may receive, in a setup completion state, a setup response frame from the second device to establish the multiband link aggregation session. The device may cause to send, in an operating mode established state, the data to the second device over the first frequency band and/or the second frequency band in the multiband link aggregation session.
1. A device, the device comprising memory and processing circuitry configured to:
determine a first frequency band and a second frequency band for sending data to a second device in a multiband link aggregation session;
cause to send, in an initial state, a setup request frame to the second device for establishing the multiband link aggregation session, the setup request frame comprising an indication of the first frequency band and the second frequency band;
identify, in a setup completion state, a setup response frame received from the second device, the setup response frame establishing the multiband link aggregation session; and
cause to send, in an operating mode established state, the data to the second device over at least one of the first frequency band or the second frequency band in the multiband link aggregation session.
2. The device of claim 1 , wherein the memory and the processing circuitry are further configured to receive, in an operating mode confirmed state, an acknowledgement frame from the second device for the multiband link aggregation session.
3. The device of claim 2 , wherein the memory and the processing circuitry are further configured to transition from operating mode established state to the operating mode confirmed state after receiving the acknowledgement frame from the second device.
4. The device of claim 1 , wherein the memory and the processing circuitry are further configured to transition from the initial state to the setup completion state after receiving the setup response frame from the second device.
5. The device of claim 1 , wherein the memory and the processing circuitry are further configured to transition from the operating mode confirmed state to the setup completion state after receiving the setup response frame from the second device.
6. The device of claim 1 , wherein the memory and the processing circuitry are further configured to cause to send a tear down frame in the operating mode confirmed state, the operating mode established state, or the setup completion state, to the second device for terminating the multiband link aggregation session.
7. The device of claim 1 , wherein the memory and the processing circuitry are further configured to cause to send a trigger frame to the second device, the trigger frame comprising information associated with changing one or more characteristics of the multiband link aggregation session.
8. The device of claim 7 , wherein the information comprises instructions for performing one or more of: (i) changing a data stream policy, (ii) changing a channel power save status, (iii) changing the second device to a third device, (iv) changing the first frequency band to a third frequency band, or (v) changing a channel associated with the second device.
9. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals.
10. The device of claim 9 , further comprising one or more antennas coupled to the transceiver.
11. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
identifying, in an initial state, a setup request frame received from a first device, the setup request frame comprising an indication of a first frequency band and a second frequency band associated with a multiband link aggregation session;
causing to send, from a second device, in a setup completion state, a setup response frame, the setup response frame establishing the multiband link aggregation session;
identifying, in an operating mode established state, data received from the second device over at least one of the first frequency band and the second frequency band, wherein the at least one of the first frequency band and the second frequency band are determined by the first device.
12. The non-transitory computer-readable medium of claim 10 , the operations further comprising causing to send, in an operating mode confirmed state, an acknowledgement frame to the first device for the multiband link aggregation session.
13. The non-transitory computer-readable medium of claim 12 , the operations further comprising transitioning from the operating mode established state to the operating mode confirmed state after causing to send the acknowledgment frame to the first device.
14. The non-transitory computer-readable medium of claim 10 , the operations further comprising transitioning from the initial state to the setup completion state after causing to send the setup response frame from the second device.
15. The non-transitory computer-readable medium of claim 10 , the operations further comprising receiving a tear down frame to the first device for terminating the multiband link aggregation session.
16. The non-transitory computer-readable medium of claim 10 , the operations further comprising receiving a trigger frame from the first device, the trigger frame comprising information associated with changing one or more characteristics of the multiband link aggregation session.
17. The non-transitory computer-readable medium of claim 16 , wherein the information comprises instructions for performing one or more of: (i) changing a data stream policy, (ii) changing a channel power save status, (iii) changing the second device to a third device, (iv) changing the first frequency band to a third frequency band, or (v) changing a channel associated with the second device.
18. A method comprising:
determining, by one or more processors of a first device, a first frequency band and a second frequency band for sending data to a second device in a multiband link aggregation session;
causing to send, by the one or more processors, in an initial state, a setup request frame to the second device, the setup request frame comprising an indication of a first frequency band and a second frequency band associated with the multiband link aggregation session;
identifying, by the one or more processors, in a setup completion state, a setup response frame received from the second device, the setup response frame establishing the multiband link aggregation session; and
causing to send, by the one or more processors, in an operating mode established state, the data to the second device over at least one of the first frequency band and the second frequency band in the multiband link aggregation session.
19. The method of claim 18 , further comprising receiving, in an operating mode confirmed state, an acknowledgement frame from the second device for the multiband link aggregation session.
20. The method of claim 18 , further comprising sending a tear down frame in the operating mode confirmed state, the operating mode established state, or the setup completion state, to the second device for terminating the multiband link aggregation session.
