A method includes: receiving, by a first communications apparatus, reference signals from a second communications apparatus; and performing, by the first communications apparatus, channel measurement based on the reference signals, and sending first CSI to the second communications apparatus in a time unit whose identifier is m, where the first CSI is used to indicate a channel state in a first reference time unit and a channel state in a second reference time unit, where an identifier of the first reference time unit is m−n1, an identifier of the second reference time unit is m−n1−n2, where m, n1, and n2 are integers, and n2 is not equal to 0. This way, matching is improved between CSI applied by a network device and a channel that is at a current moment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel state information CSI reporting method and apparatus","description":"Embodiments of a channel state information (CSI) reporting method and apparatus are disclosed.
