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: Methods, apparatuses, and computer readable media for activation and deactivation of links in a multilink device (MLD) where an apparatus of an access point (AP) MLD comprises processing circuitry configured to: encode, for transmission to a non-AP MLD, an advertisement traffic-identification (TID)-to-link mapping, the advertisement TID-to-link mapping indicating a first AP affiliated with the AP MLD is disabled, the first AP associated with a first link of the AP MLD, and decode, from the non-AP MLD, on a second link of the AP MLD, a request to enable the first AP, the second link associated with a second AP. The processing circuitry is further configured to encode, for transmission to the non-AP MLD, a response to the request to enable the first AP. An apparatus of a non-AP MLD is similarly configured.

Abstract: This disclosure describes systems, methods, and devices related to enhanced channel efficiency. A device may enable utilization of a secondary channel within a Wi-Fi network when a primary channel is engaged. The device may monitor a status of the primary channel while it is busy. The device may assess a presence of energy in the primary channel using Clear Channel Assessment (CCA) during a receiving mode. The device may provide the status of the primary channel via a block acknowledgment during frame exchanges on the secondary channel when the primary channel is determined to be idle. The device may instruct a switch back to the primary channel through a broadcast frame or a unicast frame.

Abstract: This disclosure describes systems, methods, and devices related to non-collocated multi-link device (MLD) reconfiguration. A device may establish a non-collocated MLD with multiple affiliated access points (APs) that are not geographically collocated. The device may generate a reconfiguration multi-link element for removal of an affiliated AP within the non-collocated MLD. The device may include the reconfiguration multi-link element in beacon or probe response frames transmitted by any AP affiliated with the non-collocated MLD and in the same collocated set.

Abstract: Methods, apparatuses, and computer readable media for crosslink management frames for a non-collocated access point (AP) multi-link device (MLD), the apparatus comprises processing circuitry configured to: encode an individually addressed management frame, the management frame comprising link information, the link information indicating a first link of the non-collocated AP MLD for which the management frame is intended, and configure an access point (AP) of the non-collocated AP MLD to transmit the management frame on the second link of the non-collocated AP MLD. Additionally, a non-AP MLD includes processing circuitry configured to: refrain from transmitting a second individually addressed management frame over a setup link while a third individually addressed management frame is being transmitted by a station (STA) affiliated with the non-AP MLD or the third individually addressed management frame has not successfully completed, failed due to a retry limit, or was discarded by a media access control (MAC) layer.

Abstract: For example, a wireless communication station (STA) may be configured toto transmit a reservation signal over a wireless medium at a reservation signal transmission time, for example, based on a determination that high-priority data of a high-priority Access Category (AC) is queued at the STA. 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. For example, the STA may be configured to contend the wireless medium according to a high-priority contention policy, for example, after transmission of the reservation signal, to obtain a Transmit Opportunity (TxOP) for transmission of the high-priority data.

Abstract: This disclosure describes systems, methods, and devices related to enhanced low latency. A device may generate a medium access control protocol data unit (MPDU) associated with low latency traffic based on a predefined criteria. The device may utilize an overlapping basic service set preamble detection (OBSS_PD) threshold for the low latency traffic. The device may transmit the MPDU during an ongoing OBSS PPDU transmission using an OBSS_PD spatial reuse mechanism. The device may include an indication in a preamble of the MPDU that spatial reuse is not allowed with the MPDU by another STA.

Abstract: This disclosure describes systems, methods, and devices related to enhanced aggregate preemption. A device may divide a transmit opportunity (TXOP) transmission into physical layer convergence procedure service data unit (PSDU) or physical layer (PHY) convergence protocol data unit (PPDU) transmissions. The device may establish fixed time intervals between two continuous PSDU or PPDU transmissions. The device may sense an idle status of a channel after an end of each PSDU or PPDU transmission. The device may send a first suspend request (SR) control frame after an end of receiving a current PSDU or PPDU transmission.
