Abstract: An access point (AP) multi-link device (MLD) transmits to a non-access point (non-AP) MLD, on a first link, a first frame scheduling a restricted target wake time (r-TWT) service period (SP) of a r-TWT setup for the non-AP MLD on the first link. The AP MLD transmits to the non-AP MLD, on a second link, a second frame for scheduling traffic associated with the r-TWT on the second link. The transmitting of the second frame may be responsive to a failure by the AP MLD to schedule the traffic associated with the r-TWT during the r-TWT SP on the first link.

Abstract: A station (STA) receives from an overlapping basic service set (OBSS) a first physical layer protocol data unit (PPDU) comprising a first field that indicates presence or absence of a spatial reuse parameter in a second field of the first PPDU. Based on the first field indicating presence of the spatial reuse parameter in the second field of the PPDU, the STA determines a transmit power threshold based on the spatial reuse parameter and transmits a second PPDU using a transmit power based on the transmit power threshold.

Abstract: A station (STA) receives from an access point (AP) a frame indicating a start time and a wake duration of a restricted target wake time (r-TWT) service period (SP) of an r-TWT setup for the STA. The STA transitions to an awake state at or before the start time of the r-TWT SP. The STA receives, from the AP, during the r-TWT SP: a first frame comprising a traffic identifier (TID) associated with the r-TWT and having an end of service period (EOSP) field set to 0; or a trigger frame indicating an identifier of the STA. The STA transitions to a doze state, after expiration of the wake duration of the r-TWT SP, on condition of receiving, from the AP, after expiration of the wake duration of the r-TWT SP, a second frame comprising a TID associated with the r-TWT and having an EOSP field set to 1.

Abstract: An access point (AP) transmits a first frame indicating, for a first station (STA), a first time allocation of a transmission opportunity (TXOP) and a first triggered TXOP sharing (TXS) mode, and for a second STA, a second time allocation of the TXOP and a second TXS mode. The first TXS mode and the second TXS mode may be the same or different. The AP receives from the first STA a second frame within the first time allocation in response to the first frame. The AP receives from the second STA a third frame within the second time allocation in response to the first frame.

Abstract: A non-access point (non-AP) multi-link device (MLD) transmits to an access point (AP) MLD a frame for a traffic identifier (TID) on a first link to which the TID is mapped in a TID-to-link mapping. The non-AP MLD receives from the AP MLD a trigger frame on a second link to which the TID is not mapped by the TID-to-link mapping. The non-AP MLD transmits to the AP MLD, in response to the trigger frame, a Quality of Service (QoS) null frame comprising the TID on the second link.

Abstract: An access point (AP) multi-link device (MLD) transmits, to a station (STA) MLD, a first frame indicating a first start time of a target wake time (TWT) service period (SP) scheduled on a first link between the AP MLD and the STA MLD. The AP MLD transmits, to the STA MLD, on a second link between the AP MLD and the STA MLD, a second frame indicating a second start time of the TWT SP on the first link, where the second start time is based on a cross-link switching delay associated with the STA MLD.

Abstract: An access point (AP) transmits a first frame comprising: a Target Wake Time (TWT) element indicating a restricted Target Wake Time (r-TWT) Service Period (SP) of an r-TWT setup for one or more first stations (STAs); and a quiet element indicating a quiet interval for one or more second STAs, the quiet interval overlapping with a portion of the r-TWT SP. Based on determining termination of the r-TWT SP during the quiet interval, the AP transmits a second frame, during the quiet interval, indicating termination of the quiet interval for the one or more second STAs.

Abstract: A station (STA) transmits to an access point (AP) a setup request frame indicating one or more first traffic identifiers (TIDs) associated with a trigger-enabled restricted target wake time (r-TWT) service period (SP). The STA receives from the AP a setup response frame indicating one or more second TIDs associated with the trigger-enabled r-TWT SP. The STA receives from the AP a first frame indicating a trigger-enabled r-TWT SP for the STA. Based on not receiving a second frame from the AP during a first time period within the trigger-enabled r-TWT SP, the STA transmits a non-trigger based frame following the first time period. The non-trigger based frame causes termination of the r-TWT SP.

Abstract: A non-access point multi-link device (non-AP MLD) receives from an access point multi-link device (AP MLD), while in a first power save mode, a beacon frame comprising a traffic indication map (TIM) element indicating downlink buffered units (BUs) for the non-AP MLD, where during the first power save mode the non-AP MLD wakes to listen for beacon frames on one of enabled links at least once within a listen interval. After receiving the downlink BUs from the AP MLD, the non-AP MLD switches to a second power save mode, where during the second power save mode the non-AP MLD wakes to listen for beacon frames at each target beacon transmission time (TBTT) on the enabled links until a timer expires.
