Abstract

A wireless communication system includes a first transmitter and a second transmitter. For a transmission or reception of data of a first user equipment and data of a second user equipment on resources shared by the first user equipment and the second user equipment, the first transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a first data signal of the first user equipment and a second data signal of the second user equipment, and the second transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a third data signal of the first user equipment and a fourth data signal of the second user equipment.
