Pattern Division Multiple Access: A New Multiple Access Technology for 5G

IEEE Wireless Communications, 2018
The anticipated 1000-fold increase in mobile data traffic over the next decade and the explosion of new services and applications pose great challenges for the current orthogonal multiple access (OMA)-based 4G systems. A promising solution to address these challenges is to shift from the currently predominant OMA to non-orthogonal multiple access (NOMA)

Pattern Division Multiple Access—A Novel Nonorthogonal Multiple Access for Fifth-Generation Radio Networks

IEEE Transactions on Vehicular Technology, 2017
In this paper, pattern division multiple access (PDMA), which is a novel nonorthogonal multiple access scheme, is proposed for fifth-generation (5G) radio networks. The PDMA pattern defines the mapping of transmitted data to a resource group that can consist of time, frequency, and spatial resources or any combination of these resources. The pattern is

On the performance of pattern division multiple access in 5G systems

2016 8th International Conference on Wireless Communications & Signal Processing (WCSP), 2016
Pattern division multiple access (PDMA) is one of the important candidate multiple access technologies for future 5G wireless communication systems. It can improve the spectral efficiency and support the massive connection based on the reasonable unequal diversity between users.

Pattern division multiple access (PDMA) for cellular future radio access

2015 International Conference on Wireless Communications & Signal Processing (WCSP), 2015
This paper presents a pattern division multiple access (PDMA) concept for cellular future radio access (FRA) towards the 2020s information society. Different from the current LTE radio access scheme (until Release 11), PDMA is a novel non-orthogonal multiple access technology based on the total optimization of multiple user communication system.

Uplink grant-free pattern division multiple access (GF-PDMA) for 5G radio access

China Communications, 2018
Massive 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).
