| Abstract(in English) | This paper investigates a distributed power control method based on channel gains for the grant-free non-orthogonal multiple access in the massive machine-type communications. In the proposed method, each terminal controls its transmission power based on its channel gain and the feedback reflecting other terminals' control results. This idea enables each terminal to consume only transmission power enough large to successfully transmit its packets. Our simulation results highlighted that the proposed method reduced power consumption by 17 dB below the existing distributed power selection method. |
