Data transmission method and user equipment

A terminal, comprising:

• a processor, configured to determine a frame structure in a time unit, wherein the frame structure indicates that N type-1 OFDM symbols and a GP are comprised in the time unit, a first subcarrier spacing of each type-1 OFDM symbol is Δf1, a first time length of the GP is greater than a second time length occupied by one type-2 OFDM symbol, a second subcarrier spacing of the type-2 OFDM symbol is Δf2, Δf1 is unequal to Δf2, N is a positive integer, and N is a maximum quantity of type-1 OFDM symbols comprised in the time unit after the second time length occupied by one type-2 OFDM symbol is subtracted;
• and
• a transmitter, configured to send the N type-1 OFDM symbols according to the frame structure.

A non-transitory computer-readable medium including computer-executable instructions that, when executed, facilitate carrying out a data transmission method comprising:

• determining, by a first terminal, a frame structure in a time unit, wherein the frame structure indicates that N type-1 orthogonal frequency division multiplexing (OFDM) symbols and a guard period (GP) are comprised in the time unit, a first subcarrier spacing of each type-1 OFDM symbol is Δf1, a first time length of the GP is greater than a second time length occupied by one type-2 OFDM symbol, a second subcarrier spacing of the type-2 OFDM symbol is Δf2, Δf1 is unequal to Δf2, N is a positive integer, and N is a maximum quantity of type-1 OFDM symbols comprised in the time unit after the second time length occupied by one type-2 OFDM symbol is subtracted;
• and
• sending, by the first terminal, the N type-1 OFDM symbols according to the frame structure.
