Title: PRECODING MATRIX INDICATION METHOD, TERMINAL, AND NETWORK APPARATUS
Abstract:
Provided in the present disclosure are a precoding matrix indication method, terminal, and network apparatus. The method comprises: a terminal receiving control signaling from a network apparatus, the control signaling comprising precoding information having N bits, and N being a positive integer; the terminal determining, according to a scheduling resource, a precoding granularity number, and determining, according to the precoding granularity number, precoding information bits of each precoding granular unit in the precoding information having N bits, wherein said precoding granular unit comprises at least one subband, and each subband comprises at least one PRB; and the terminal acquiring a precoding matrix indicated by the precoding information bits of each precoding granular unit.
