Dec 26, 2019 · In this paper, we propose a downlink multiple-input single-output (MISO) transmission scheme, which is assisted by an intelligent reflecting surface (IRS).

We optimize the beamforming vectors and the IRS phase shift matrix for minimizing transmission power. Furthermore, we propose an improved quasi-degradation.

The use of non-orthogonal multiple access (NOMA) has been shown to improve spectrum efficiency, making it a key consideration in 6G wireless networks [2].

By employing the IRS-assisted NOMA, we design a more practical transmission scheme, which achieves the same performance as DPC. We further investigate ...
