  • Patent number: 12225519
    Abstract: Multi-link operations can provide higher network throughput and improved network flexibility compared to traditional techniques for wireless communication. Embodiments of the present invention provide a method of frame transmission that prevents constrained MLDs from transmitting and receiving frames on multiple links simultaneously using a novel and reliable group addressed frame transmission schedule for constrained MLDs. Group addressed frames are frames that are transmitted to several devices (e.g., broadcast) listening on a wireless link. It is important to carefully schedule group addressed frames for reception by MLDs to prevent IDC interference. According to some embodiments, group addressed frames are only transmitted when all MLDs listening on a wireless link are not transmitting data to prevent IDC interference.
