Abstract
This application provides a communication method, a communications apparatus, and a system. The method may include receiving, by a terminal device, a first group of precoded reference signals and a second group of precoded reference signals. The method may also include feeding back first indication information based on a channel state information (CSI) feedback-based transmission scheme, where the first indication information is used to determine a plurality of precoding vectors, at least one of the plurality of precoding vectors is determined by using the first group of precoded reference signals, and at least one of the plurality of precoding vectors is determined by using the second group of precoded reference signals.
