Abstract: Optimal determination of transmit power level for MLDs in A Wireless Local Area Network (WLAN). An AP can establish synchronous downlink multi-link operations with another MLD. A first link and a second link between the AP and the MLD both operate in a same sub-band. The AP can then determine the same power level for both the first link and second link. After establishing the same power level, the AP can then determine a second power level for the first link and a third power level for the second link. The second power level is greater than the third power level. The AP can then provide the second power level for the first link and the third power level for the second link.

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: Optimal determination of wireless network pathway configurations may be provided. A computing device may detect, at a first network Access Point (AP), interference 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: Improved mesh performance using Overlapping Basic Service Set (OBSS) coloring and transmission scheduling may be provided. A controller may determine that a plurality of Access Points (APs) in a mesh network each have a Received Signal Strength Indicator (RSSI) that is in a predetermined range. Next, the controller may assign, in response to determining that the plurality of APs each have the RSSI that is in the predetermined range, OBSS colors to links between the plurality of APs to limit packet collision in the mesh network between the plurality of APs. The controller may then create a transmission schedule for transmissions between the plurality of APs in the mesh network based on the assigned OBSS colors.

Abstract: The present technology enables inter-network routing by dynamically optimizing data paths for traffic destined for wired clients attached to a wireless access point in a wireless mesh network with a plurality of wireless access points. The present technology can also influence steering of wireless device connections within the wireless mesh network when high amounts of data traffic are exchanged between nearby mesh wireless access points.

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.
