The method includes: a simultaneous transmission of the M sources in a time interval with allocation of at least one sub-band per source and at least one cooperative retransmission for a time interval of at least one relay node taken from among the M sources and the L relays which is selected using a selection strategy with allocation of at least one sub-band per node selected.

A wireless communication system includes a first communication device and a second communication device. The first communication device obtains a plurality of radio frequency (RF) signals corresponding to different communication protocols from a plurality of communication systems. A frequency of each of the plurality of RF signals is upconverted to a different frequency, and a phase noise is introduced in the plurality of RF signals. The plurality of RF signals corresponding to different communication protocols are multiplexed into a mmWave RF signal of a specified frequency and a defined pilot tone along with the mmWave RF signal is transmitted. The second communication device captures the mmWave RF signal having the defined pilot tone over-the-air. At least one RF signal is down converted to a source frequency and the phase noise is estimated in the one extracted RF signal based on the defined pilot tone which is reduced concurrently.

A relay-based data transmission approach to improve the reliability and/or the energy efficiency of uplink NOMA. A relay node (RN) is employed to improve the performance of both weak and strong UEs. In some embodiments, superposition coding and NOMA-based transmission are applied at the RN and the UEs, respectively, to improve the achievable rates of the UEs.
