Classification: CPC H | IPC H

Claim 7:
8. A method comprising:
configuring a data beam to be transmitted to a user equipment (UE) to have a null area in a direction of a satellite earth station (ES), the null area defining a space within a coverage area of the data beam in which a signal from the data beam is suppressed, wherein configuring the data beam further comprises:
generating a steering vector to the ES;
obtaining a UE channel matrix via a sounding reference signal (SRS);
determining a rank value;
determining a beamforming vector based on increasing a received signal power at the UE without exceeding a power leakage constraint in the direction of the ES, wherein the power leakage constraint is a function of (i) a threshold parameter associated with a nulling level in the direction of the ES and (ii) the steering vector to the ES; and
generating, based on the beamforming vector, a beamforming precoder configured to directional null the data beam in the direction of the ES; and

transmitting, via a transceiver, the generated data beam to the UE.
