Publication number: 20250047375Abstract: Dynamic Transmission Opportunity (TXOP) sharing between overlapping Basic Service Sets (BSSs) in wireless networks. A sharing Access Point (AP) initiates a process by generating and wirelessly transmitting a control frame to allocate its TXOP to a shared AP in an overlapping BSS. Subsequently, the sharing AP receives a return TXOP frame from the shared AP, indicating the return of any unused TXOP portion. The sharing AP then has the flexibility to either resume its own transmissions using the returned TXOP or reallocate it to an alternative AP. Using the techniques in dense wireless networking environments enables efficient spectrum utilization through dynamic TXOP allocation and reclamation. The techniques address challenges of resource management in multi-AP scenarios, improving overall network performance and reducing interference in overlapping coverage areas.Type: ApplicationFiled: July 26, 2024Publication date: February 6, 2025Applicant: NEWRACOM, Inc.Inventors: Si-Chan NOH, Joonsoo LEE
