Abstract

Embodiments of a high efficiency subchannel selective transmission (HE SST) access point (AP) and an HE SST station (STA) are generally described herein. The HE SST AP may determine a temporary primary channel for an HE SST STA. The HE SST AP may communicate with the HE SST STA in a plurality of channels that includes the temporary primary channel and further includes a primary channel. The HE SST AP may determine trigger-enabled target wake time service periods (TWT SPs) for exchange of frames between the HE SST AP and the HE SST STA on the temporary primary channel. The trigger-enabled TWT SPs may be determined to not overlap with target beacon transmission times (TBTTs) at which beacon frames that include delivery traffic indication maps (DTIMs) are to be sent on the primary channel by the HE SST AP.
