  • Patent number: 10917859
    Abstract: A technique is disclosed for reducing interference in a communication system including a plurality of wireless devices. A first device transmits a frame (e.g., an RTS frame or a CTS frame) to a second device, the frame including information from which a non-target third device may use to estimate potential interference at the first device based on a proposed transmission to a fourth device. The information includes at least one of an interference and sensitivity factor (ISF), transmit power, and reciprocity factor (a difference between an antenna receive gain and an antenna transmit gain). Using the information in the frame to estimate the potential interference at the first device, the third device may choose to proceed with the proposed transmission if the estimated potential interference is less than a threshold; or withdraw or modify the proposed transmission if the estimated potential interference is greater than or equal to a threshold.
