Abstract: Optimal determination of a Wireless Local Area Network (WLAN) sounding method and system may be provided. An Access Point (AP) selects a subchannel for the partial sounding. The AP then sounds the selected subchannel. A client station responds with Channel State Information (CSI). The AP can receive the CSI, from the client station, in response to the sounding. Based on the CSI from the selected subchannel, the AP extrapolates the CSI to determine predicted CSI for a wider bandwidth channel.

Abstract: Inter-protocol interference reduction for hidden nodes may be provided. A first service end point may determine that an inter-protocol interference is present on a channel. Next, an initial packet failure count value on the channel may be determined. A transmit (Tx) power for selected packets may then be increased until a subsequent packet failure count value on the channel is less than the initial packet failure count value.

Abstract: Learning-based service migration in mobile edge computing may be provided. First, a service migration policy may be created for a network that includes a plurality of edge clouds configured to provide a service to users. Next, a movement of a user receiving the service from a source edge cloud may be detected. The source edge cloud may be associated with a first area and the detected movement may be from the first area to a second area. Then, the service migration policy may be applied to determine whether to migrate the service for the user from the source edge cloud. In response to determining to migrate the service, a target edge cloud may be identified and the service for the user may be migrated from the source edge cloud to the target edge cloud. The service migration policy may then be updated based on a success of the migration.

Abstract: In one embodiment, a method includes identifying a number of configured proactive repetitions in downlink transmissions from the base station, selecting k antenna states for receiving repetitive downlink transmissions among the number of antenna states, where k equals the number of configured proactive repetitions, and where each of the k antenna states corresponds to each of the repetitive downlink transmissions, transmitting a CSI report for each of the k antenna states to the base station, where a CSI report for an antenna state is used by the base station to adjust configurations for the corresponding downlink transmission, receiving signals for each of the k repetitive downlink transmissions from the base station using each of the k antenna states, and decoding the downlink transmission based on k sets of received signals, each of the k sets being received using each of the k selected antenna states.

Abstract: Optimal determination of wireless network pathway configurations may be provided. A computing device may detect, at a first network Access Point (AP), inference on a channel with a second AP. Then, the computing device can check availability of a redundant radio at the second AP. Based on the availability, the computing device can establish a new radio link with the redundant radio at the second AP and reroute data traffic over the new radio link to the second AP. After establishing the new radio link, the computing device can then sever the channel with the second AP.

Abstract: Described herein are devices, systems, methods, and processes for improving the accuracy of access point (AP) location in a Wi-Fi network using client device data and AP ranging measurements. APs may be deployed across a specific area. The APs can range to one another and form a matrix of measurements. Techniques such as semidefinite programming or multidimensional scaling (MDS) can be employed to transform these AP-to-AP ranges into a set of coordinates. Client devices in the area may also range to the APs. The client devices may provide their location measurement report (LMR) feedback and geo-position estimation to the network. The client devices-provided data, along with the AP-to-AP matrices, may be returned to a location server. The location server can use the data to refine the accuracy of the AP-to-AP graph and ascertain the most probable geo-position of the APs.

Abstract: Crest Factor Reduction (CFR) parameters are determined for a dual band Power Amplifier (PA). A first band of the dual band PA is associated with a first Multi-Link Operation (MLO) link and a second band of the dual band PA is associated with a second MLO link. Determining the CFR parameters comprises determining based on a configuration of the first MLO link and the second MLO link. A first portion of the CFR parameters is provided to a first crest factor reduction block. First portion of the CFR parameters comprises a first clipping threshold associated with the first band and first filter coefficients associated with the first band. A second portion of the CFR parameters is provided to a second crest factor reduction block. The second portion of the CFR parameters comprises a second clipping threshold associated with the second band and second filter coefficients associated with the second band.

Abstract: An arrangement of three radios maybe provided. The three radios define first and second outer data links and a middle data link. Access to the arrangement of three radios can be biased to the middle data link in one direction upon a data transmission through the first and second outer data links being dominate in an opposite direction. Data transmission with enhanced multi-link single radio (eMLSR) client devices can be prioritized lower than data transmission with simultaneous transmit and receive radio (STR) client devices and non-simultaneous transmit and receive radio (NSTR) client devices. A radio can be configured for data transmission with a client device. The range of the radio is limited when the data traffic through the radio exceeds a determined number of bytes of data in a determined amount of time.
