Abstract: Techniques for delegated peer-to-peer scheduling are provided. A first peer-to-peer device determines one or more wireless channels allocated for peer-to-peer communication, and receives a request indicating a set of transmission characteristics from a second peer-to-peer device that uses the first peer-to-peer device as a communications proxy. The first peer-to-peer device schedules wireless resources of the one or more wireless channels to a plurality of peer-to-peer devices based at least in part on the set of transmission characteristics, and performs peer-to-peer communications with the second peer-to-peer device in accordance with the scheduled wireless resources.

Abstract: Systems and techniques for performing traffic management in a wireless network using predictive traffic identifier (TID)-to-link mapping are described. An example technique includes obtaining one or more metrics associated with communication between a client station (STA) and an access point (AP) in a wireless network. The communication between the client STA and the AP is based on a first TID-to-link map. A second TID-to-link map is determined, based at least in part on evaluating the one or more metrics with a machine learning model. Communications between the client STA and AP are performed, based on the second TID-to-link map.

Abstract: Techniques are provided for optimizing performance of a multi-link device (MLD). In one embodiment, a controller receives information about a filter response for a first multi-link device (MLD, determines, based on the information about the filter response, a filtering transitional region of the first MLD indicating a range of frequencies where there is energy leakage due to the first MLD device operating in a simultaneous transmission and reception (STR) mode, determines cost metrics for a plurality of channels by identifying a STR and non-STR (NSTR) ratio for each of the plurality of channels, and assigns, based on the filtering transitional region and the cost metrics, a first radio of an access point (AP) to one of the plurality of channels to enable the first MLD to operate in the STR mode when communicating with the first radio.

Abstract: Techniques for uplink scheduling in a wireless network are disclosed. A wireless access point (AP) receives, from a wireless station (STA), a buffer status report (BSR) reflecting data accumulated at the STA for uplink to the AP. The AP identifies, based on the BSR, a scheduling mode under which the data was accumulated at the STA. The AP schedules an uplink parameter for the STA, based on the identified scheduling mode. The uplink parameter relates to at least one of: (i) an uplink transmission for the STA or (ii) a buffer status poll for the STA. The AP transmits, to the STA, an allocation relating to the scheduled uplink parameter for the STA.

Abstract: Automating and extending path tracing through wireless links is provided by receiving a request to perform a network trace over a wireless link provided by an Access Point (AP) configured as a transparent forwarder between a trace source and a trace target; monitoring a trace packet from a first time of arrival at the AP, a first time of departure from the AP, a second time of arrival at the AP, and a second time of departure from the AP; monitoring a buffer status of the AP at the first time of arrival and the second time of arrival; and in response to identifying a network anomaly based on the trace packet and the buffer status, adjusting a network setting at the AP.

Abstract: Techniques for improved peer-to-peer communication are provided. A first peer-to-peer device associated with a first wireless AP, may transmit a first peer-to-peer transmission schedule to a second wireless AP, where the first peer-to-peer transmission schedule was accepted by the first wireless AP. In response to receiving an acceptance from the second wireless AP, the first wireless AP transitions from to the second wireless AP. The first peer-to-peer device performs peer-to-peer communication in accordance with the first peer-to-peer transmission schedule.

Abstract: The present disclosure describes an access point that shifts data streams subject to QoS requirements to links that are mapped to handle such traffic. The access point includes one or more memories and one or more processors communicatively coupled to the one or more memories. The one or more processors determine, based on a first traffic identifier for a first data stream, that the first data stream is subject to QoS requirements and in response to determining that the first data stream is subject to QoS requirements, determine a first link that is mapped to the first traffic identifier. The one or more processors carry the first data stream on the first link.

Abstract: The present disclosure describes an access point that coordinates infrastructure and non-infrastructure communications. The access point includes one or more memories and one or more processors communicatively coupled to the one or more memories. The one or more processors determine that access points of an extended service set are refraining from using a first channel and communicate, to a first device, a first beacon comprising a channel usage element indicating that the first channel is available for the first device to use to communicate directly with a second device.

Abstract: Wireless dynamic file exchange is provided by, in response to a triggering network condition occurring, initiating an exchange of a parameter file including non-layer two content via a 802.11 message, such as a Generic Advertisement Service (GAS) message between an access point (AP) and a station (STA) connected to the AP; and in response to determining that the exchange was unsuccessful, terminating a connection between the AP and the STA. The parameter file may be sent over several messages and update the parameters for a new session or an existing session. Devices that do not conform to the updated parameters may be disassociated from the AP and re-connect to receive and implement the updated parameters.

Abstract: Techniques for facilitating client mobility without performing re-association are described. An example technique includes receiving, from a first access point (AP), an indication of at least one second AP neighboring the first AP. A multi-link association is performed. The multi-link association includes establishing a first link with the first AP and pre-establishing a second link with the second AP. After performing the multi-link association, the first AP is communicated with at a first instance in time via the first link.
