Abstract
Embodiments of this application provide a channel matrix determining method, an apparatus, and a system, relating to the field of communication technologies, to resolve a technical problem that a manner in which a network device determines a precoding matrix based on an existing PMI indicator is not applicable to long-distance communication. The method includes: A terminal device obtains a plurality of reference signals, determines a first channel matrix based on the plurality of reference signals, and feeds back, to a network device, first information indicating some channel elements in the first channel matrix. The terminal device may further receive a downlink signal determined based on the first information and sent by the network device. A channel element in the some channel elements is determined based on signal strength and/or a time-frequency resource of the reference signal.
