This application provides a diversity communication method and apparatus, to provide a diversity transmission solution. A first device maps a plurality of modulation symbols corresponding to one transport block to a plurality of antenna ports, where a plurality of consecutive modulation symbols are mapped to one antenna port in each mapping. Then, the first device maps the modulation symbols on each antenna port to a frequency domain resource corresponding to the antenna port, and frequency domain resources corresponding to different antenna ports do not overlap. The frequency domain resources corresponding to the different antenna ports do not overlap. In other words, the transport block is transmitted on different channels, and therefore diversity transmission of the transport block is implemented. In addition, when the modulation symbols are mapped to the antenna ports, the plurality of consecutive modulation symbols are mapped each time. In this mapping manner, a phase difference between the plurality of consecutive modulation symbols may be kept undamaged, so that a communication system is enabled to maintain a low peak to average power ratio PAPR.
