The embodiment of the present invention provides a method of data transmission, which includes: according to the power ratio of the near-user equipment and the far-user equipment in two paired user equipment, the transmission power is allocated to the near-user equipment and the far-user equipment, where the power ratio is a ratio in the first set of ratios, and at least one ratio in the first set of ratios can be used. Selected from the second set of ratios, the second set of ratios is a set of power ratios represented by optional composite constellation points in a constellation diagram with an interval of 1, and data transmission is carried out according to the transmission power of the near-user device and the transmission power of the far-user device. Therefore, embodiments of the present invention can provide multiple power ratios between near-user devices and far-user devices in two paired user devices, increase the flexibility of base stations to near-user devices and far-user devices, and at the same time help to improve the performance gains obtained by MUST transmission.
