Abstract: Communicating among stations in a network includes, from each of multiple stations in the network, transmitting information indicating which other stations from which that station is able to reliably receive transmissions. A schedule for communicating among the stations is determined based on the information from the stations and transmitting the schedule over the network. The schedule includes a plurality of time slots during which respective contention groups of stations are assigned to communicate using a contention-based protocol.

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: Methods, systems, and devices for wireless communications are described. A first device may receive signaling associated with a traffic class from a second device. The first device may determine that the traffic class is included in a set of known traffic classes based on a set of features associated with the signaling. In response to determining that the traffic class is included in the set of known traffic classes, the first device may use a machine learning model to obtain a prediction of an application associated with the signaling. The prediction may be based on the set of features. The machine learning model may be trained at the first device or the second device. The first device may receive information associated with the machine learning model from the second device.

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: 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: This disclosure provides systems, methods and apparatuses for channel selection and channel selection planning in a network including a root AP (RAP) and a number of satellite APs (SAPs). The root AP may assign operating channels for one or more of the satellite APs in a manner that optimizes network performance by considering the impact that each of the satellite APs (as well as their respective client devices) may have on the network. In some implementations, the root AP may provide centralized channel selection planning for the network based a number of network parameters observed by one or more of the satellite APs. The network parameters may include, for example, channel conditions, traffic loads, traffic patterns, service needs of client devices, available channels, and other network utilization information observed by one or more of the satellite APs.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer-readable media, for serving AP selection in a network having multiple access points (APs). In one aspect, a serving AP selection unit can steer a device (such as a client station, STA, or a child AP) based on a quality of service profile (such as a capacity requirement or a delay requirement) of the device. The device may be initially associated with a first AP (as the current serving AP) in the network. The serving AP selection unit may select a second AP as a new serving AP for the device, and cause the device to associate with the second AP rather than the first AP. The selection of a serving AP may take into account delay or hop count in addition to path capacities for various paths in the network.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enhanced channel selection in a network having multiple access points (APs). The enhanced channel selection may optimize the overall performance of the network by incorporating considerations about the impact on other APs in a big-picture view of the network. In one aspect, enhanced channel selection may combine a first channel selection process at a first AP (based on first channel selection by the first AP) with a second channel selection at a Multi-AP Controller. Coordination between the first AP and the Multi-AP Controller may improve a channel selection technique to optimize channel selection based on considerations of the overall network.

Abstract: Methods, systems, and devices for wireless communication are described for buffer status report triggering. An access point (AP) may identify that an amount of uplink data queued in a buffer of a station is less than a predetermined threshold. The AP may determine that a buffer status report (BSR) trigger condition is satisfied by estimating that the station has data to transmit to the access point, or by identifying that the access point will schedule an uplink transmission for the station. The AP may transmit a BSR trigger to the station based at least in part on identifying that the amount of uplink data queued in the buffer is less than the predetermined threshold and determining that the BSR trigger condition is satisfied.

Abstract: Methods, systems, and devices are described for wireless communications. A communication device may utilize enhanced roaming techniques to dynamically adjust signal strength thresholds in a high density AP environment. For instance, a communication device determines a signal strength of a communication link between a wireless device and an access point (AP). The communication device further compares the signal strength value to at least a low threshold and a high threshold and performs a channel scan for the communication link when the signal strength value is below the low threshold. The communication device also adjusts the low threshold when the signal strength value is greater than the high threshold.
