[Abstract] In this paper, a partially self-powered non-orthogonal multiple access (NOMA) frame work by combining the NOMA and wireless power transfer (WPT) technologies is proposed. With the high spectral efficiency and short distance transmission, partially self-powered NOMA can achieve high efficiency in wireless energy harvesting and multiple user data transmission. It can be used for uplink information feedback, relay transmission, information decoding and etc. Then the potential research directions on this topic is discussed, and the achievable rate region of a two user system as preliminary results is analyzed.
