    Abstract: Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority. The controller may then create a negotiation between the victim AP and the infringing AP, wherein the negotiation comprises managing future transmissions of the victim AP and the infringing AP.

    Abstract: Techniques for wireless device roaming are disclosed. These techniques include identifying a wireless client entity for roaming from a first infrastructure entity to a second infrastructure entity. The techniques further include agreeing, between the client entity and the first infrastructure entity, on one or more roaming conditions defined using transition parameters for transition of a first data flow for the client entity from the first infrastructure entity to the second infrastructure entity, the one or more transition parameters including a sequence number relating to the dataflow. The techniques further include determining that a first condition defined in terms of a transition parameter of the agreed one or more roaming conditions is met, and, based on the determining, transitioning from providing the first dataflow from the first infrastructure entity to the client entity to providing the first data flow from the second infrastructure entity to the client entity.

    Abstract: Techniques and systems for enhancing transmit opportunity (TXOP) sharing for multi-access point coordination (MAPC) are described. An example technique includes obtaining, for each access point (AP) of a plurality of APs in a MAPC group, historical mobility information of client stations (STAs) associated with the AP. A number of the client STAs associated with each AP that satisfies a mobility criteria is determined based on the historical mobility information. A determination of whether to enable TXOP sharing is made for each AP and an indication of the determination is transmitted to the AP. Another technique includes estimating traffic demand for a first set of client STAs associated with an AP. A second set of client STAs to make available for TXOP sharing is determined. Signal strength information associated with a communication link between each client STA in the second set and the AP is transmitted.

    Abstract: Dynamic spectrum access mode based on station capabilities is provided by categorizing functionalities of Access Points (APs) and stations (STA) in a wireless network; identifying interference induced by external signaling devices on channels in the wireless network; calculating an impact factor of the interference based on proximity of the external signaling devices to the wireless network, a pattern of the external signaling devices, and an extent of overlap with frequencies used by the external signaling devices and the wireless network; and in response to identifying a given STA that is paired with a given AP in the wireless network, wherein the given STA and the given AP are both categorized as being capable of both multilink communications and preamble puncturing, assigning network resources for the given STA to communicate with the given AP via one of multilink communications or preamble puncturing based on the impact factor of the interference.
