  • Patent number: 11926993
    Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Various implementations relate generally to coordinated transmit power control for sharing time and frequency resources of a wireless medium. Particular implementations relate more specifically to coordinated access point spatial-reuse-multiple-access techniques for sharing the time and frequency resources of a transmission opportunity. According to such techniques, an access point that wins contention and gains access to the wireless medium for the duration of a transmission opportunity may limit the transmit powers of the access points selected to share the time and frequency resources such that interference from the selected access points does not prevent stations associated with the winning access point from successfully decoding packets transmitted by it.
