Abstract
A signal transmission method includes: performing hierarchical modulation on service data that needs to be sent, so as to obtain a hierarchically modulated signal; determining energy per resource element (EPRE) of a modulated signal of each layer of the service data according to power configuration information; and sending the hierarchically modulated signal to user equipment UE according to the determined EPRE of the modulated signal of each layer. According to the signal transmission method and apparatus provided in the embodiments of the present invention, the system spectrum utilization efficiency and the system throughput can be greatly improved.
