Abstract: A sending device sends, by using a first resource and a second resource, a reference signal corresponding to a first port. The first resource and the second resource are respectively on a first OFDM symbol and a second OFDM symbol that are not adjacent to each other. The first port belongs to a first port set or a second port set, a reference signal corresponding to a port in the first port set corresponds to a first cover code on the first resource and the second resource, a reference signal corresponding to a port in the second port set corresponds to a second cover code on the first resource and the second resource, and the first cover code is different from the second cover code.

Abstract: A precoding matrix indication method and a related device. In the method, a transmit end can group K combination coefficients based on an amplitude value of each of the K combination coefficients, to obtain Q combination coefficient groups, and determine a phase value of each combination coefficient in each combination coefficient group. The amplitude value of each combination coefficient is determined by using a same amplitude quantization bit quantity and a same amplitude quantization rule. In addition, phase quantization bit quantities and/or phase quantization rules used by at least two of the Q combination coefficient groups are different.
