Precoding weight calculation method and related apparatus

An apparatus, comprising:

• one or more processors coupled to memory storing instructions for execution by the one or more processors to:
• obtain a plurality of first channel estimation values and a plurality of second channel estimation values based on a resource block group (RBG), wherein the plurality of the first channel estimation values respectively correspond to a plurality of first subcarriers corresponding to a first terminal, the plurality of the second channel estimation values correspond to a plurality of second subcarriers corresponding to a second terminal, and the plurality of the first subcarriers and the plurality of the second subcarriers are included in the RBG;
• obtain a first equivalent channel matrix based on some or all of the plurality of the first channel estimation values, and obtain a second equivalent channel matrix based on some or all of the plurality of the second channel estimation values;
• obtain a plurality of first equivalent channel coefficients based on some or all of the first channel estimation values and the first equivalent channel matrix, and obtain a plurality second equivalent channel coefficients based on some or all of the second channel estimation values and the second equivalent channel matrix;
• after the plurality of first equivalent channel coefficients and the plurality of second equivalent channel coefficients are obtained, obtain a first precoding weight and a second precoding weight based on the plurality of the first equivalent channel coefficients and the plurality of the second equivalent channel coefficients;
• precode a signal based on the first precoding weight and the second precoding weight;
• and
• output the signal.
