Abstract: A signal transmission method includes: processing, by a base station, a first baseband signal, a second baseband signal, a third baseband signal, and a fourth baseband signal by using a VAM matrix, to obtain four processed signals; performing precoding processing on the four processed signals to obtain four coded signals; and sending the four coded signals to a mobile terminal by using four radio frequency ports. The four radio frequency ports are in a one-to-one correspondence with the four coded signals. A first processed signal is the same as a third processed signal, a second processed signal is the same as a fourth processed signal. The first processed signal is obtained by performing superposition on the first baseband signal and the third baseband signal, and the second processed signal is obtained by performing superposition on the second baseband signal and the fourth baseband signal.

Abstract: A signal transmission method is performed by a base station. The method includes: determining, a first carrier signal that is to be sent in a first cell on a first carrier and a second carrier signal that is to be sent in a second cell on a second carrier; mapping, the first carrier signal and the second carrier signal to N physical ports of an RRU, so that within a same OFDM symbol, a type B symbol used to transmit a pilot in the first carrier signal and a type B symbol used to transmit a pilot in the second carrier signal are mapped to different physical ports, and a total power of signals sent on each of N physical channels is not greater than a rated power of the RRU; and sending, the first carrier signal and the second carrier signal through the N physical ports.
