Disclosed are a method and device for transmitting data. The method comprises: a transmitting terminal determines in N basic parameter sets a first target basic parameter set of a first beam for transmitting first data, different basic parameter sets of the N basic parameter comprising different frequency-domain base parameter sets and/or different time-domain basic parameter sets, and N being an integer greater than or equal to 2; and the transmitting terminal transmits the first beam on a time-domain resource, a spatial-domain resource, and a frequency-domain resource based on the first target basic parameter set; this can be adapted to requirements of diverse data in a network.
