Abstract: Apparatuses and methods for precoding matrix indicator (PMI)-based data beam nulling with a channel state information (CSI) report. An apparatus includes a transceiver configured to communicate via a wired or wireless communication medium and a processor coupled to the transceiver. The processor is configured to identify restricted PMI beams in a nulling direction for supported ranks; receive, via the transceiver from a user equipment (UE), a CSI report including a rank, a PMI, and channel quality indicator (CQI) feedback; and determine whether the reported PMI is restricted. The processor is further configured to select an alternative PMI among a number of unrestricted PMIs for the reported rank; boost a reported CQI if a reduced transmit power is configured; and select a modulation coding scheme (MCS) and generate a precoder for a data beam based on at least one of: the CSI report, the alternative PMI, and the boosted CQI.

Abstract: Methods and apparatuses in a wireless communication system. A base station (BS) includes a transceiver and a processor. The processor regulates a transmit power in a direction of an earth station or a predefined receiver by: calculating a power flux density for the BS to the earth station or the predefined receiver; calculating an equivalent antenna gain for other base stations; calculating a directional power back-off level for the other base stations with respect to the earth station or the predefined receiver; generating a restricted precoding matrix indicator based on the calculated directional power back-off level; generating an N1-N2 bitmap for the BS; and applying the N1-N2 bitmap for signal transmission to at least one UE. The N1-N2 bitmap is generated based on: physical parameters of the earth station of the predefined receiver; physical parameters of the BS; an operator input metric; or restricted precoding matrix indicator.

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.
