Abstract
A method, apparatus, and system of optimizing transmission of data in a power domain non-orthogonal multiple access system is described. The method includes generating a first encoded data stream associated with a first user device, and generating a second encoded data stream associated with a second user device. The method also includes generating a superimposed signal using the first encoded data stream and the second encoded data stream. In addition, the method includes determining a first minimum beam power associated with a first beam vector, and determining a second minimum beam power associated with a second beam vector. The method also includes transmitting the superimposed signal to the first user device at the first minimum beam power, and transmitting the superimposed signal to the second user device at the second minimum beam power.
