Abstract: For example, an Access Point (AP) may be configured to transmit a frame including a prioritized-access enabled/disabled field to indicate whether a prioritized-access contention mechanism is to be enabled or disabled over a wireless medium. For example, the prioritized-access contention mechanism may be configured to allow a prioritized station (STA) to transmit a reservation signal over the wireless medium at a reservation signal transmission time, and to contend the wireless medium according to a high-priority contention policy to obtain a Transmit Opportunity (TxOP) after transmission of the reservation signal. For example, the reservation signal transmission time may be based on an end of a predefined time duration from a start of a contention period. For example, the reservation signal may be configured to indicate a busy Clear Channel Assessment (CCA) to a receiving STA.

Abstract: For example, an Access Point (AP) may be configured to configure a trigger frame to indicate an allocation of a triggered contention-based period to be allocated within a Transmit Opportunity (TxOP) of the AP. For example, the trigger frame may be configured to indicate that only one or more eligible non-AP stations (STAs), which are eligible to communicate during the triggered contention-based period, are to be allowed to contend a wireless medium during the triggered contention-based period. For example, the AP may be configured to transmit the trigger frame to initiate the allocation of the triggered contention-based period. For example, a non-AP STA may be configured to be allowed to contend the wireless medium for a transmission during the triggered contention-based period, for example, based on a determination that the non-AP STA is to be defined as an eligible non-AP STA for the triggered contention-based period.

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
