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

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).
