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.
