DATA TRANSMISSION METHOD AND APPARATUS

WIPO Patent Application WO/2018/054248

A1

A data transmission method comprises: a sending end sends data to a reception end on one or more OFDM symbols in a modulation unit, the time length of the modulation unit being the time length of two 15kHz LTE OFDM symbols having normal cyclic prefixes, the modulation unit being formed by seven or eight OFDM symbols having a subcarrier interval of 60kHz, or the modulation unit being formed by seven OFDM symbols having a subcarrier interval of 60kHz as well as a first gap, or the modulation unit being formed by eight OFDM symbols having a subcarrier interval of 60kHz as well as a second gap, the OFDM symbols having a subcarrier interval of 60kHz comprising cyclic prefixes and valid data, and in the modulation unit, two types of different cyclic prefix lengths being used on the seven OFDM symbols having a subcarrier interval of 60kHz and the eight OFDM symbols having a subcarrier interval of 60kHz.
