Uplink grant-free pattern division multiple access (GF-PDMA) for 5G radio access
China Communications, 2018Massive machine type communication (mMTC) is one of the key application scenarios for the fifth generation mobile communication (5G). Grant-free (GF) transmission can reduce the high signaling overhead in mMTC. Non-orthogonal multiple access (NMA) can support more users for mMTC than orthogonal frequency division multiple access (OFDMA).

Interleaver-Based Pattern Division Multiple Access with Iterative Decoding and Detection
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017Pattern Division Multiple Access (PDMA) is a novel non-orthogonal multiple access scheme proposed to meet the demand of massive connection in the future 5G communications. PDMA is based on the joint design of transmitter and receiver. The multiuser signals are superposed on the multiple signal domains based on different characteristic patterns at the ...
