Abstract
This application provides channel information obtaining methods and communications apparatuses, to reduce pilot overheads and a delay of obtaining channel information. In an example method, a terminal device receives one or more first reference signals on a dport of the terminal device, where the first reference signal is a reference signal from a first network device. The terminal device obtains a first channel vector hbased on the received first reference signal, where ha channel vector of a channel between the dport of the terminal device and the first network device. The terminal device receives N second reference signals on the dport of the terminal device. The terminal device obtains a second channel vector hbased on the received second reference signal.
