Abstract:
An information transmission apparatus and method and a communications system. The information transmission method includes: performing constellation transform respectively on first symbols to be transmitted to a first receiving device and second symbols to be transmitted to a second receiving device; performing power allocation respectively on the constellation transformed first symbols and the constellation transformed second symbols and superimposition, to form superimposed symbols; and interleaving imaginary parts and real parts of the superimposed symbols and then transmitting them. Hence, data demodulation performance of the UE may further be improved based on conventional NOMA.

Claim (Index 19):
A communications system, configured to perform nonorthogonal multiple access (NOMA), the communications system comprising:\n a transmitting device configured to perform constellation transform respectively on first symbols to be transmitted to a first receiving device and second symbols to be transmitted to a second receiving device, perform power allocation respectively on the constellation transformed first symbols and the constellation transformed second symbols and superimposition to form superimposed symbols, and interleave imaginary parts and real parts of the superimposed symbols and then transmit the superimposed symbols; the first receiving device configured to receive signals transmitted by the transmitting device and de-interleave imaginary parts and real parts of the signals, in a case where a modulation scheme of the second receiving device is unknown, take the second symbols as interference, and demodulate and decode the first symbols based on a constellation used by the first symbols, and in a case where the modulation scheme of the second receiving device is known, demodulate and decode the first symbols based on a complex constellation formed by superimposing the first symbols and the second symbols; and the second receiving device configured to receive signals transmitted by the transmitting device and de-interleave imaginary parts and real parts of the signals, and demodulate and decode the second symbols based on the complex constellation formed by superimposing the first symbols and the second symbols.
