Abstract: This disclosure provides methods, devices and systems related multi-link wireless communication. A method may include establishing, between the first WLAN device and a second WLAN device, a multi-link association that enables a first wireless communication link and a second wireless communication link. The method may include determining a temporal key for the multi-link association. The method may include encrypting a first and second media access control (MAC) protocol data unit (MPDU) based on the temporal key. The method may include preparing a first frame including the encrypted first MPDU and a second frame including the encrypted second MPDU. The method may include assigning packet numbers from a set of sequential packet numbers to the first and second frames. The method may include transmitting the first frame over the first wireless communication link and the second frame over the second wireless communication link.

Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly for address translation during multi-link operation in a wireless local area network (WLAN). The method may include establishing one or more wireless communication links with a station (STA) including a first wireless communication link. The method may include receiving, via the first wireless communication link, a first frame including a first address field that includes a first link media access control (MAC) address associated with the STA. The method may include determining that the STA is associated with a first network MAC address. The method may include removing the first link MAC address from the first address field of the first frame, and inserting the first network MAC address of the STA in a second address field of the first frame. The method may include transmitting the first frame to a first local area network (LAN) device.

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: A delta configuration is transmitted to a UE requesting a handover wherein the delta configuration details changes that are required for the current UE configuration in order to execute the handover. The handover is initiated via a measurement report transmitted to a currently serving source eNode B from the UE. The measurement report can comprise one or more of current radio conditions, current UE configuration or a preferred target eNode B if the handover is a inter eNode B handover. In a inter eNB handover, the current UE configuration is forwarded to the preferred target eNode B by the source eNode B. The target eNode B generates the delta configuration and transmits it to the source eNode B in a transparent container which is subsequently forwarded to the UE.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for load balancing network traffic in a wireless network. In one aspect, an access point may determine a plurality of client devices that are associated with an overloaded channel of the wireless network. The access point may identify a first client device of the plurality of client devices based, at least in part, on an airtime consumed on the overloaded channel. The access point may determine one or more alternate paths between the access point and the first client device. The access point may forecast airtime to be used by the first client device on channels of the one or more alternate paths, and steer wireless network traffic of the first client device to a first alternate path of the one or more alternate paths based, at least in part, on the forecasted airtime.

Abstract: Apparatuses and methods are disclosed that may allow a wireless device to be steered between a number of different access points (APs) based, at least in part, on a type of traffic associated with the wireless device. In some aspects, a first AP may monitor a traffic flow associated with the wireless device, identify a traffic type of the traffic flow based on one or more characteristics of the traffic flow, and selectively switch an association of the wireless device between the first AP and one of a number of second APs based, at least in part, on the identified traffic type.
