摘要： Systems and methods which implement cooperative techniques at wireless network access points to provide interference mitigation are shown. Embodiments utilize cooperative antenna beam adaptation techniques wherein antenna beam selection, selective antenna beam transmission power, and/or antenna beam null selection is implemented based upon the communication environment created by a plurality of access points. Additionally or alternatively, embodiments utilize cooperative antenna beam isolation techniques wherein narrow channel filters are implemented with respect to antenna beam signals and/or shielding is provided between various antenna beams based upon the communication environment created by a plurality of access points. Embodiments additionally or alternatively utilize cooperative antenna beam coordination techniques wherein transmission and/or reception of signals is coordinated, the use of antenna beams is coordinated, and/or interference cancellation is implemented based upon the communication environment created by a plurality of access points.
