Original Abstract Submitted
Embodiments of this application disclose methods and apparatuses for obtaining channel parameters. In an implementation, a method includes, sending, by a network device, a precoded reference signal and indication information indicating K selected frequency domain bases, wherein the precoded reference signal is generated on P ports by mapping K virtual ports associated with the K selected frequency domain bases to each of the P ports through beamforming, wherein K is an integer greater than 1, and wherein the P ports are precoded channel state information reference signal (CSI-RS) ports of the network device and user equipment, and receiving, by the network device, a linear superposition coefficient sent by the user equipment, wherein the linear superposition coefficient corresponds to M frequency domain bases in the K selected frequency domain bases and T ports in the P ports, wherein 1≤T≤P, and 1≤M≤K.
