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: 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.

Abstract: New wireless networks can perform enhanced beamforming training for a multiple access technique, such as orthogonal frequency division multiple-access (OFDMA). The configurations of the stations and the networks presented herein provide a multiple-station beam refinement protocol (MSBRP) that may be used to train the transmit end and/or the receive end for the stations in a dense wireless local area network (WLAN). The MSBRP can have at least two phases. The first phase concurrently trains the receive side of multiple responder stations from one set of training signals sent from an initiator station. Then, each responder station can send training signals to the initiator station in a set of ordered phases associated with each responder station. The MSBRP eliminates inefficiencies associated with conducting multiple BRPs that include only pairs of stations.

Abstract: This disclosure describes systems, methods, and devices related to dynamic unavailability management. A device may receive an in-device coexistence mode request frame from a station device (STA) indicating support for an in-device coexistence mode. The device may transmit a response frame to the STA to enable the in-device coexistence mode. The device may classify types of interference experienced by the STA as indicated in the received in-device coexistence mode request frame. The device may generate one or more physical protocol data units (PPDUs) for transmission based on the classified interference types. The device may cause to send the one or more PPDUs to the STA.

Abstract: This disclosure describes systems, methods, and devices related to adaptive synchronization management. A device may monitor a synchronization status of the device with respect to a medium it is using. The device may detect a loss of synchronization with the medium. The device may initiate a MediumSynch Timer decrement with a predetermined initial value upon detecting the loss of synchronization. The device may receive Restricted Target Wake Time (rTWT) service period information from an access point (AP). The device may identify contention periods within a Basic Service Set (BSS) based on the received rTWT service period information. The device may reset the MediumSynch Timer to enable participation in the contention period at a start of the rTWT service period (SP).

Abstract: This disclosure describes systems, methods, and devices related to enhanced ICF exchange. A device may cause to send an Initial Control Frame Trigger frame (ICF TF) to one or more transmit opportunity (TXOP) responders. The device may identify a first response from at least one of the one or more TXOP responders, wherein the first response uses a non-high throughput (HT) duplicate physical layer (PHY) convergence protocol data unit (PPDU) format. The device may identify a second response from the at least one of the one or more TXOP responders.

Abstract: This disclosure describes systems, methods, and devices related to predictable latency access category (AC). A device may control the initiation of a contention period for network communication. The device may broadcast a reservation/defer signal at a predetermined time after the start of the contention period for an Access Category for Predictable Latency (AC_PL). The device may receive reservation/defer signals from connected Station (STA) devices. The device may process the received reservation/defer signals to manage network access priorities and channel access specifically for the AC_PL. The device may adjust network parameters based on the received reservation/defer signals to minimize collisions.

Abstract: This disclosure describes systems, methods, and devices related to enhanced transmission. A device may generate an aggregated medium access control protocol data unit (A-MPDU) frame, wherein the A-MPDU is associated with transmission of n Network Coding (NC) encoded frames. The device may divide the A-MPDU frame into k data frames and (n−k) parity frames within the A-MPDU frame. The device may transmit the k data frames. The device may transmit to a station device (STA) at least one of the (n−k) parity frames separately after the data frames in response to packet drops in the k data frames.
