Abstract: Techniques for coordinating traffic statistics and managing accounting sessions for multi-link operation are provided. A first communications link with a second network device is established by a first network device. A first accounting request to a third network device is transmitted by the first network device, where the first accounting request indicates that the second network device comprises a station multi-link device (STA MLD). A first accounting response is received by the first network device, indicating whether the third network device supports statistic aggregation. Traffic statistics for the first communication link is collected by the first network device, and reported to the third network device in accordance with the first accounting response.

Abstract: Techniques for improved multi-link operations are provided. A first link between a first access point (AP) multi-link device (MLD) and a non-AP MLD is established. A first idle timeout timer is generated for the first link, and an indication of one or more links between the non-AP MLD and a second AP MLD is received from the non-AP MLD. An indication of the first link is transmitted to the second AP MLD and from the first AP MLD. In response to determining that one or more link termination criteria are satisfied with respect to the first link, the first link is terminated, where subsequent to terminating the first link, the non-AP MLD continues to exchange data with the second AP MLD using the one or more links.

Abstract: A network controller and various methods for grouping access points for AFC are presented. A method includes assigning a plurality of access points to a plurality of groups based at least in part on stored AFC reports for the plurality of access points, determining, for each group of the plurality of groups, a centroid and an uncertainty range, and generating, for each group of the plurality of groups, an AFC query using the determined centroid and uncertainty range for the corresponding group.

Abstract: Systems and techniques for mitigating interference to incumbent users in a wireless network are described. An example technique includes receiving an indication of interference on a channel that an incumbent user within a wireless network is operating on. A source of the interference is determined using key performance indicator(s), in response to the indication. A set of actions is determined and performed to mitigate the interference. Another example technique includes receiving an indication of interference on a channel that an incumbent user within a wireless network is operating on. Interference information is obtained from a controller associated with the wireless network and includes KPI(s) associated with a set of access points (APs) operating on the channel. A source of the interference is determined based on the interference information. A set of actions to mitigate the interference are determined and performed on one or more of the set of APs.

Abstract: Enhanced network level information for power control is described. The enhanced network level information enables network connected electronic devices to enter and exit standby modes based on system level information. The network level information also enables the use of a respective network connected device in a seamless manner from the perspective of the user, while decreasing the amount of energy consumed by the device when not in active operation. In some examples, a Network Monitoring Application (NMA) classifies electronic devices into power control categories, monitors a physical environment associated with the plurality of connected electronic devices, and provides a power control signal to the various electronic devices upon detection of a change in the physical environment.

Abstract: Successive interference mitigation in Automated Frequency Coordination (AFC) may be provided. A plurality of messages may be received from a respective plurality of Access Points (APs). Each of the plurality of messages may indicate a respective channel used by a respective one of the plurality of APs associated with the message. An indication may be received that an Interference to Noise (I/N) ratio is above a predetermined threshold in a Fixed Service (FS) channel associated with an FS. At least one of the plurality of APs may be identified as a cause of the I/N ratio being above the predetermined threshold in the FS channel based on a channel used by the identified at least one of the plurality of APs and the FS channel. An action may be taken against the identified at least one of the plurality of APs to lower the I/N ratio.

Abstract: A client device may receive, from a computing device, a message indicating that a session duration of a current session is nearly over. The client device may close the current session as soon as the client device is idle for more than a configurable interval. A new session may be started with the computing device by the client device.

Abstract: Techniques for wireless communication are disclosed. These techniques include determining that a first wireless access point (AP) has a failure to connect to a controller. The techniques further include identifying one or more neighbor APs, for the first AP, as candidate rescue APs, selecting a rescue AP, from among the candidate rescue APs, and establishing a secure connection from the first AP to the rescue AP. The techniques further includes transmitting diagnostic data from the first AP to the controller using the secure connection from the first AP to the rescue AP. The diagnostic data relates to the failure to connect from the first AP to the controller, and the controller is configured to use the diagnostic data to assist in establishing a connection from the first AP to the controller that bypasses the rescue AP
