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.

Joint transmissions of data in a wireless communication system using a non-orthogonal multiple access transmission scheme

An apparatus serves a plurality of user equipments in a wireless communication system. For transmitting/receiving data of a plurality of user equipments, which include at least a first user equipment and a second user equipment, on resources shared by the plurality of user equipments, the apparatus transmits/receives a first data signal of the first user equipment and second data signal of the second user equipment using a non-orthogonal multiple access, NOMA, scheme. The first data signal and the second data signal are modulated using different waveforms prior to superposition of the first and second data signals.

Communicating data of a first user equipment and data of a second user equipment on shared resources of a wireless communication system

A user equipment for operating in a wireless network, wherein the wireless network utilizes a first number of resources for serving communicating UEs, comprises a wireless interface for communicating in the wireless network; and a controller configured for selecting, for communicating in the wireless network, from a second number of predefined subsets of the first number of resources, at least one subset. The second number is larger than the first number and the second number of predefined subsets is based on a mapping of the first number of resources into the second number of subsets using an Euler-square mapping.
