Abstract
Embodiments of the present invention provide a device to device data transmission method and a device. The device to device data transmission method includes: determining, by a terminal, a frame structure of a subframe used for communication; and implementing, by the terminal, communication with another terminal by using the subframe; where a minimum quantity of orthogonal frequency division multiplexing OFDM symbols used for transmitting demodulation reference signals DMRSs in the subframe is 3, and the OFDM symbols used for transmitting the DMRSs are distributed non-consecutively in the subframe. The embodiments of the present invention are used to improve reliability of data transmission in D2D communication when a channel changes quickly.
