Abstract: A power control method and a device are provided. The method includes: modulating a first bit stream by using a first modulation scheme to obtain a first modulation symbol, modulating a second bit stream by using a second modulation scheme to obtain a second modulation symbol, and modulating, by using a third modulation scheme, a combined bit stream obtained by combining the first bit stream and the second bit stream to obtain a joint modulation symbol; modifying the first modulation symbol by using a first modification coefficient to obtain a first modified modulation symbol, and modifying the second modulation symbol by using a second modification coefficient to obtain a second modified modulation symbol; separately performing power control processing on the first modified modulation symbol and the second modified modulation symbol, and sending, to a terminal device, a combined modulation symbol obtained after the power control.
