Abstract
Disclosed is 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), including 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, and coordinating AP updates in the AP candidate set when a coordinated AP that is part of the AP candidate set performs a channel switch to a second primary channel operating on a different bandwidth stream than a bandwidth stream of the first primary channel.

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;
- and
- coordinating AP updates in the AP candidate set when a coordinated AP that is part of the AP candidate set performs a channel switch to a second primary channel operating on a different bandwidth stream than a bandwidth stream of the first primary channel.
A method of setting conditions for a sharing access point (AP) to select a shared AP from an AP candidate set of the sharing AP for a shared transmission opportunity (SH-TXOP), comprising:
- selecting, by the sharing AP, an AP as the shared AP if a bandwidth of a primary channel of the AP is within a bandwidth of the SH-TXOP;
- and
- restricting, by the sharing AP, allocation to any shared AP in the AP candidate set of time resources beyond a duration of the SH-TXOP and frequency resources outside of the SH-TXOP bandwidth.
A method of a shared transmission opportunity (SH-TXOP) switching, comprising:
- simultaneously transmitting an SH-TXOP switch of a plurality of SH-TXOP switches by a plurality of shared access points (APs), each of the SH-TXOP switches containing identical content;
- and
- including, by a sharing AP, in an SH-TXOP announcement frame, information regarding whether an SH-TXOP switch frame will be transmitted by the plurality of shared APs.
A method of associating a station (STA) with a shared access point (AP) in a shared transmission opportunity (SH-TXOP), comprising:
- generating temporal security keys with a sharing AP having an AP candidate set that includes the shared AP.
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;
- 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.
