Pattern Division Multiple Access (PDMA)
Pattern division multiple access (PDMA) is a kind of non orthogonal multiple access technology based on the principle of the introduced reasonable diversity between multi user and joint design between transmitter and receiver to promote the capacity. PDMA can be used in 5G typical scenarios like eMBB, URLLC and mMTC, enhancing spectrum efficiency, increasing connections and decreasing latency. Followed by research work on key technologies of PDMA, PDMA was formerly included in the new technology trend report of ITU R and now is being hotly discussed in 5G new radio standardization in 3GPP, also PDMA has passed the MIIT of China 5G trial. Further, more and more PDMA based extension technologies are being proposed by academics, pushing forward PDMA development.
