Multi link TXOP aggregation
A method of providing multi-link operation channel access in a multi-link network includes initiating a first backoff countdown and a second backoff countdown associated with a first link and a second link of the multi-link network, respectively, and in response to the first backoff countdown reaching zero, determining whether the second backoff countdown is less than or equal to an aggregation threshold, and in response to determining that the second backoff countdown is less than or equal to the aggregation threshold, transmitting a first frame and a second frame on the first and second links.
1. A method of providing multi-link operation channel access in a multi-link network, the method comprising:
initiating a first backoff countdown and a second backoff countdown associated with a first link and a second link of the multi-link network, respectively; and
in response to the first backoff countdown reaching zero,
determining whether the second backoff countdown is less than or equal to an aggregation threshold; and
in response to determining that the second backoff countdown is less than or equal to the aggregation threshold,
suspending the second backoff countdown;
transmitting a first frame and a second frame on the first and second links; and
resuming the second backoff countdown after completion of transmission on the second link.
2. The method of claim 1 , further comprising:
determining that the first and second links are idle.
3. The method of claim 1 , further comprising:
maintaining a contention window of the second link the same as that prior to transmitting the second frame.
4. The method of claim 1 , wherein the first and second frames have time-aligned start and end times.
5. The method of claim 1 , further comprising:
padding a shorter one of the first and second frames to equalize frame durations of the first and second frames.
6. The method of claim 1 , further comprising:
receiving the aggregated threshold from an access point of the multi-link network.
7. The method of claim 1 , wherein at least one of the first and second frames comprises an encapsulation of a physical header, one or more MAC headers, and one or more data payloads.
8. A method of providing multi-link operation channel access in a multi-link network, the method comprising:
initiating a first backoff countdown and a second backoff countdown associated with a first link and a second link of the multi-link network, respectively; and
in response to the first backoff countdown reaching zero,
determining whether the second backoff countdown is less than or equal to an aggregation threshold; and
in response to determining that the second backoff countdown is less than or equal to the aggregation threshold,
suspending the second backoff countdown;
transmitting a first frame and a second frame on the first and second links; and
generating a new start value for the second backoff countdown,
wherein the new start value is a random value less than a contention window of the second link.
9. A method of providing multi-link operation channel access in a multi-link network, the method comprising:
initiating a first backoff countdown and a second backoff countdown associated with a first link and a second link of the multi-link network, respectively; and
in response to the first backoff countdown reaching zero,
determining whether the second backoff countdown is less than or equal to an aggregation threshold; and
in response to determining that the second backoff countdown is less than or equal to the aggregation threshold,
suspending the second backoff countdown;
transmitting a first frame and a second frame on the first and second links; and
in response to determining that the second backoff countdown is greater than the aggregation threshold,
transmitting a first frame on the first link and not transmitting on the second link.
