Abstract
A method for reducing interference at a first user equipment (UE) includes receiving, by a second communications controller, a request to reduce interference at the first UE, the first UE being served by a first communications controller. The method also includes determining, by the second communications controller, a beam adjustment in accordance with uplink transmission measurements of the first UE and a second UE, the beam adjustment to aim a transmission to the second UE away from the second UE and towards an angle orthogonal to a first direction of the first UE relative to the second communications controller, the second UE being served by the second communications controller. The method further includes pre-adjusting, by the second communications controller, the transmission with the beam adjustment, and transmitting, by the second communications controller, the pre-adjusted transmission to the second UE.
