Wireless technology that can conFigure wide-area IoT systems with high data rates is required toward 6G. To further expand area coverage, it is necessary to improve the data rate of the conventional machine type communications (MTC) such as LTE-M and mMTC at the edge of the coverage area. In this paper, we propose an orthogonal frequency division multiplexing (OFDM) with symbol-edges truncating transmission (STTOFDM) for data rate enhancement. In the proposed STT-OFDM scheme, only a part of the cyclic prefix (CP)-OFDM symbols, which is the legacy communication scheme adopted to 4G and 5G, is transmitted. On the receiver side, zeros are inserted where the no transmission took place at the transmitter side before normal OFDM demodulation is performed. The energy per one-symbol transmission is expected to be reduced by the proposed STTOFDM. We evaluate the achievable throughput and show the usefulness of the proposed STT-OFDM scheme. The proposed STT-OFDM can improve the throughput of the CP-OFDM by about 1.5 times even in low SNR environments.
