FIELD: information technology.
SUBSTANCE: set of physical transmit antennae can be divided into a plurality of groups of physical transmit antennae. Further, a precoding vector for a particular group of physical transmit antennae from the plurality of groups of physical transmit antennae can be formulated. Furthermore, the particular group of physical transmit antennae can form a particular virtual antenna. By way of another example, another precoding vector for another group of physical transmit antennae from the plurality of groups of physical transmit antennae can be formulated, and the other group of physical transmit antennae can form another virtual antenna. The precoding vector can be applied to a signal for transmission over the particular virtual antenna, and the other precoding vector can be applied to another signal for transmission over the other virtual antenna.
EFFECT: efficient use of a physical transmit antenna and power amplifiers associated with the physical transmit antenna.
