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.
