Abstract
This application provides a precoding matrix indicator feedback method and a communication apparatus, and relates to the field of communication technologies. The method is applied to a precoding process, and specifically includes: a terminal that first determines a first PMI, and then sends the first PMI to an access network device. The first PMI indicates a precoding matrix W. The precoding matrix W includes R precoding vectors w, where i=0,1,2, . . . , R−1. Each precoding vector wis a column vector with a length of N×N×N. Nrepresents a quantity of antenna panels. Nrepresents a quantity of ports in a first dimension on one antenna panel. Nrepresents a quantity of ports in a second dimension on the antenna panel. N, Nand Nare all positive integers, and at least one of N, N, and Nis greater than or equal to 2.
