Abstract
An apparatus in a wireless communication system is configured to perform a method for directional beam nulling of SRS-based data beams. A base station (BS) includes a transceiver and a processor. The processor is configured to transmit a data beam to at least one user equipment (UE). The processor is also configured to configure the data beam 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. The data beam is configured by: generating one or more steering vectors to the ES; obtaining a UE channel matrix via a sounding reference signal (SRS) and determining a rank value; and generating a beamforming precoder configured to directional null the data beam in the direction of the ES.
