Shared transmission opportunity operation in multi-access point coordination

1. A method of setting conditions for an access point (AP) to be included in an AP candidate set of a coordinating AP for a transmission opportunity (TXOP), comprising:

setting a first primary channel of the AP as part of the AP candidate set of the coordinating AP within a basic service set (BSS) operating bandwidth of the coordinating AP;

determining that a coordinated AP that is part of the AP candidate set is sharing the first primary channel with the coordinating AP; and

in response to the determining, coordinating AP updates in the AP candidate set when the coordinated AP performs a channel switch to a second primary channel operating on a different bandwidth stream than a bandwidth stream of the first primary channel.

2. The method of claim 1 ,

wherein an operating frequency of the first primary channel is identical to the operating frequency of the second primary channel.

3. The method of claim 2 ,

wherein the operating frequency of first primary channel and the second primary channel is 20 megahertz (MHz).

4. The method of claim 1 ,

wherein the channel switch from the first primary channel to the second primary channel is temporary, and

wherein the channel switch is further performed for at least one station (STA) associated with the coordinated AP.

5. The method of claim 4 ,

wherein the coordinated AP switches back to the bandwidth stream of the first primary channel when the TXOP is concluded.

6. A station (STA) connected to a shared access point (AP) and comprising:

a memory; and

a processor coupled with the memory and configured to:

perform at least one operation on a first primary channel;

determining that the STA is sharing the first primary channel with the shared AP;

in response to the determining, receive notification, from the shared AP, of a temporarily switch to a second primary channel operating on a different bandwidth stream than a bandwidth stream of the first primary channel; and

temporarily switch to the second primary channel, based on the notification.

7. The STA of claim 6 ,

wherein the STA performs transmission of downlink and uplink orthogonal frequency division multiple access (OFDMA) resources on the second primary channel when the temporary switch is performed.

8. The STA of claim 6 ,

wherein the notification is received via a shared transmission opportunity (SH-TXOP) SWITCH frame sent by the shared AP.

9. The STA of claim 6 ,

wherein an operating frequency of the first primary channel is identical to the operating frequency of the second primary channel.

10. The STA of claim 9 ,

wherein the operating frequency of first primary channel and the second primary channel is 20 megahertz (MHz).
