Abstract: A data transmission method and apparatus. The method includes: determining a second weight matrix based on a first weight matrix indicated by a first PMI fed back by a terminal, and then converting the second weight matrix into a non-equal power weight matrix based on a non-equal coefficient matrix, so that a network device can send data with non-equal power on different radio frequency channels. This improves power utilization, implements a better beam side lobe, better mitigates a performance loss caused by inaccurate channel information, and improves data transmission quality.
