Abstract
According to embodiments of the present invention, a quantity of available state values of a reference signal configuration is increased by indicating a dual-codeword transmission mode and two single-codeword transmission modes, where the two single-codeword transmission modes are distinguished by using a new data indicator NDI. Therefore, higher-rank (such as 16-layer or 24-layer) MU-MIMO can be supported, increasing system spectral efficiency significantly, and improving MU-MIMO configuration flexibility and resource scheduling effectiveness.
