Abstract: This disclosure describes systems, methods, and devices related to enhanced multi-link single-radio (EMLSR). A device may utilize multiple links in a time-shared manner. The device may assign one of the multiple links as a primary link for legacy STAs. The device may assign remaining links as non-primary links. The device may initiate a transmit opportunity (TXOP) on a non-primary link when the primary link is occupied. The device may transmit a control frame from a non-primary link in response to an initial control frame when the primary link is idle, wherein the control frame indicates discontinuation of frame exchange on the non-primary link.

Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The STA may determine a portion of a channel occupied by an incumbent device.

The STA may encode a physical layer convergence procedure protocol data unit (PPDU) for transmission in the combined RU. The PPDU may be encoded in accordance with joint coding across the RUs of the combined RU.

Abstract: For example, an Access Point (AP) may be configured to determine that a high-priority contention period is to be initiated during a particular contention period. For example, the AP may be configured to determine that the high-priority contention period is to be initiated during the particular contention period based on a reservation signal received from a station (STA) over a wireless medium during the particular contention period. For example, the AP may be configured to allow the AP to contend the wireless medium during the high-priority contention period according to a high-priority contention policy, for example, to obtain a Transmit Opportunity (TxOP) for transmission of downlink (DL) data to one or more STAs.

Abstract: An access point station (AP) configured for ultra-high reliability (UHR) communication in a wireless local area network (WLAN) may receive low-latency (i.e., time-sensitive) traffic during a transmission opportunity (TXOP) by transmission of an initial frame encoded to indicate whether or not preemption for low-latency (LL) traffic is enabled during the TXOP. When preemption for LL traffic is enabled during the TXOP, the AP may encode downlink (DL) physical-layer protocol data units (PPDUs) for transmission within the TXOP. The DL PPDUs may be transmitted with an extended short interframe spacing (xIFS) therebetween. Each of the DL PPDUs may indicate whether the xIFS that follows a DL PPDU is enabled for preemption.

Abstract: A non-AP STA of a multi-link device (STA MLD) may be configured to encode a multi-link (ML) probe request frame for transmission to an access point STA (AP) of an AP MLD comprising a plurality of affiliated APs. When the probe request frame is sent outside the context of active scanning, to discover an AP of the AP MLD the ML probe request frame may be encoded to have an Address 1 field set to a broadcast address and an Address 3 field set to a BSSID of the AP, or encoded to have the Address 1 field set to a basic service set identity (BSSID) of the AP's BS. The non-AP STA may refrain from transmitting the ML probe request frame to the AP of the AP MLD in a corresponding link when another non-AP STA of the AP MLD has already received a ML probe response that included complete information from any one of the APs of the AP MLD in any link.

Abstract: A non-Access Point Extremely High Throughput Station (non-AP EHT STA) initiates a Quality-of-Service (QoS) setup by sending a Stream Classification Service (SCS) Request frame to an associated access point (AP). The SCS request frame may be encoded to have a request type field set to “Add” and may contain an SCS Descriptor element having a traffic description field, a traffic classification field, and a Multi-Link Operation (MLO) field. The non-AP EHT STA may decode an SCS Response frame from the AP that indicate whether the QoS setup has been added. The non-AP EHT STA may then exchange a QoS traffic flow with the associated AP in accordance with the QoS setup when the QoS setup has been added. When the QoS traffic flow ends, the non-AP EHT STA may encode a second SCS Request frame for transmission to the AP with the request type field set to “Remove” to delete the QoS setup.
