Abstract: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for high efficiency (HE) beacons. HE supported access points (APs) and stations (STAs) may operate on resource deployments used for Wi-Fi technology and without support for legacy devices, also referred to as a greenfield deployment. An AP may identify updated capability information and transmit a HE physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a beacon frame. A STA may receive, from the AP, the HE or EHT PPDU and identify an indication of change to a content or format of the beacon frame relative to a reference beacon frame. Based on the identified indication, the STA may then determine an updated content or format for the beacon frame and process the beacon frame or skip processing for one or more portions of the beacon frame.

Abstract: The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.

Abstract: An access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field, one or more secondary change sequence fields, and a critical update flag subfield. The first change sequence field carries a value of the most-recent critical update for the first AP. The one or more secondary change sequence fields carry values of the most-recent critical updates for the one or more respective secondary APs. The critical update flag subfield carries an indication of a change in value of at least one of the secondary change sequence fields. The first AP transmits the frame over the first communication link of the AP MLD.

Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media that support station performance enhancement with multi-link operations. An example method may include determining at least one network metric related to at least one link between a station (STA) and access points (APs) and determining at least one connection parameter related to at least one application operating on the STA. The method may include selecting a mode of multi-link operations based at least in part on the network metric and the connection parameter, wherein the mode of multi-link operations comprises one or more of: a multi-link mode in which the STA operates over a first link and a second link at a same time or a single-link mode in which the STA operates over one of the first or second links and communicating with the one or more APs according to the selected mode.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to receive information indicating a wake time period from a STA and use the received wake time period to schedule communication with the STA. The apparatus may use the received wake time period to determine a target transmission time for transmitting a trigger frame to the STA. The apparatus may transmit a beacon to the STA and then transmit the trigger frame to the STA at the target transmission time following the beacon. The apparatus may also indicate an offset from the beacon that the apparatus will use for communication with the STA based on the wake time period of the STA.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include determining a signal strength indication from a field of a management frame associated with one or more information elements, comparing the signal strength indication to a first threshold and a second threshold, and performing a low-power operation for at least a remaining portion of the management frame based on determining that the signal strength indication is: greater than the second threshold, or less than the first threshold, or greater than the second threshold and less than the first threshold.

Abstract: Methods, systems, and devices for wireless communication are described. A station may be communicating with an access point during a first active communication period. The communication may be performed in a first power mode. The station may switch to a second power mode to transition to a sleep period. The station may determine, based on traffic indicator metric(s), whether to perform a speculative wakeup and switch to the first power mode at the end of the sleep period.

Abstract: Methods and devices are described for wireless communications associated with a multidimensional algorithm for roaming. In one aspect, an access point (or like device) transmits a beacon signal. The access point receives, from a station in receipt of the beacon signal, a probe signal including at least one metric. The access point transmits a response signal based at least in part on the received probe signal, the response signal including information associated with the at least one metric.
