| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper investigates the robustness of our distributed power control method for the grant-free non-orthogonal multiple access (GF-NOMA) in massive machine-type communications. Our method monitors reference signals, used for GF-NOMA, for each terminal (e.g., a sensor) to estimate the utilization of power levels. As these reference signals reach within a more limited area, the estimated utilization becomes more heterogeneous between terminals, and as a result, our method may show worse performance. Our simulation results highlighted that our method provided lower power consumption than the existing random power selection method by 14 dB. |
