Abstract

The future sixth-generation (6G) technologies are expected to support large-deployment of low-powered wireless connections with high data rate and ultra-low latency. In this regard, two technologies named as power-domain non-orthogonal multiple access (PD-NOMA) and ambient backscatter communication (AmBC) are discussed in this conference. The backscatter tag in AmBC uses the incident radio-frequency (RF) signal to modulate its own information and reflect it toward the readers. Furthermore, the combination of PD-NOMA and AmBC will provide high spectral and energy-efficiency to support large-scale Internet-of-things (IoT) networks. It is shown that BC-PD-NOMA transmission scheme can realize simultaneous energy and spectrum cooperation between uplink and downlink users, which is important to support massive connectivity and stringent energy constraints in ultra-massive machine type communications (umMTC).
