1. A method comprising:
detecting an infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP;
adding information associated with the infringement event to an infringement list, wherein the information includes a Media Access Control (MAC) address associated with the infringing AP;
receiving, by a controller, the infringement list;
notifying, by the controller, the infringement event to the infringing AP;
determining, by the infringing AP, whether a transmission associated with the infringement event is low latency and high priority;
when the transmission is not low latency and high priority, modifying, by the infringing AP, future transmissions based on a notification; and
when the transmission is low latency and high priority:
notifying, by the infringing AP, that the transmission is low latency and high priority to the controller, and
creating, by the controller, 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.
