Precoding matrix indicator PMI feedback method
In a 3D MIMO scenario with 16 antenna ports, antenna ports can be extended in different directions because of different configuration manners of the antenna ports. An apparatus and method where different antenna port counting manners are determined in different configurations are provided, so that in different configurations, a matrix whose dimension is 8 and a matrix whose dimension is 2 are determined in a precoding codebook, and a value of a PMI is fed back to indicate a precoding matrix.
