Abstract
A technique is disclosed for reducing interference in a communication system including a plurality of wireless devices. A first device transmits an RTS-TRN frame including a Request to Send (RTS) portion and a first beam training sequence to determine whether a communication medium is available to communicate with a second device. If the communication medium is available, the second device transmits a CTS-TRN frame including a Clear to Send (CTS) portion and a second beam training sequence. One or more neighboring devices that receive the RTS-TRN frame and/or the CTS-TRN frame configure their respective antennas to generate one or more nulls aimed at the first and second devices when transmitting signals, as long as the first and second devices are communicating based on a duration field in the RTS-TRN frame and/or CTS-TRN frame. This reduces interference at the first and/or second devices.
