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.

Abstract: A carrier bearing method includes obtaining transmit power of each carrier borne on all power amplifiers in a radio remote unit after detecting that transmit power of a carrier borne on a power amplifier in the radio remote unit changes; adjusting a correspondence between the carriers and the power amplifier in the radio remote unit according to the obtained transmit power; and bearing each carrier on its corresponding power amplifier according to the adjusted correspondence. The device and base station are used to implement the above method.
