Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for multi-link operation. A first wireless local area network (WLAN) device (such as an AP) may establish a multi-link association between the first WLAN device and a second WLAN device. The multi-link association may coordinated by an upper media access control (U-MAC) layer of the first WLAN device that is capable of transmitting data to the second WLAN device via a first wireless communication link using a first WLAN interface and a second wireless communication link using a second WLAN interface. This disclosure provides several alternatives for handling packet numbering and fragmentation at the U-MAC layer or at each of the first WLAN interface and the second WLAN interface.

Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period. In some other implementations of synchronized channel access, an access point supporting synchronized channel access that wins contention after one or more consecutive synchronized channel access periods during which no other synchronized access points won contention, may be entitled to an extended TXOP.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QoS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

Abstract: Uplink reporting and logical channel prioritization in multiflow operation is described. In some embodiments, uplink reporting for multiflow operation utilizes bearer level splitting where the UE associates bearers or logical channel groups (LCGs) with cells for uplink reporting. In some embodiments, uplink reporting for multiflow operation utilizes packet level splitting where the UE groups buffers for all LCGs into a common pool for uplink reporting. In packet level splitting embodiments, the UE may perform uplink reporting based on the total amount of data available for transmission in the common buffer pool or by applying scaling coefficients associated with the serving cells. Some embodiments manage mapping of logical channel payloads to uplink grants for multiflow operation.

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: A first access point (AP) detects a communication between a client device and a second AP. The first AP determines at least one criteria for AP steering is satisfied. AP steering is then used by the first AP to cause the client device to associate with the first AP, or a particular network of the first AP. For example, the first AP may transmit a disassociation message to the client device. The disassociation message may identify the second AP associated with the client device and cause the client device to disassociate from the second AP. After the client device disassociates from the second AP, the client device may select and associate with the first AP. The first AP may manage which network the client device associates with using a blacklist at the first AP.

Abstract: A hybrid device can implement functionality to automatically configure itself to form a home network with other network devices. If it is determined that the hybrid device is the central access point of a hybrid network, operating parameters are determined for the central access point. The central access point can then operate in conjunction with other non-CAP hybrid devices of the hybrid device to determine how to configure the non-CAP hybrid device. The configuration of the non-CAP hybrid device can be determined based, at least in part, on a communication link performance measurement between the CAP and the non-CAP hybrid device. Furthermore, the hybrid network can also be monitored to ensure that the hybrid devices do not repeatedly or randomly switch between different configurations.

Abstract: Systems and methodologies are described that facilitate employing a variety of medium access control (MAC) header formats in wireless communications. The MAC header formats can be specialized for a particular type of data included in a protocol data unit (PDU). In addition, the MAC headers can have a variable length to accommodate payloads of varying sizes without incurring unnecessary overhead. Further, mechanisms are provided to enable direct access and delivery of control PDUs to associated protocol layers to ensure better quality of service treatment.
