Abstract
A method includes generating, by a processor, first indication information based on N reference signals, where N is an integer and N≥2. The first indication information indicates a plurality of component vectors for constructing a precoding matrix and a superposition coefficient of each component vector of each of M precoding vectors for constructing the precoding matrix upon which a precoding of M reference signals is based, where M is an integer and 1≤M<N. The method also includes transmitting the first indication information by way of an antenna.
