In embodiments the method includes sending, by a base station, indication information to a terminal, wherein the indication information is used to instruct the terminal to send uplink data without weighting the uplink data or after weighting the uplink data by using an identity matrix and receiving, by the base station, the uplink data sent by the terminal. The method further includes selecting, by the base station, a first pre-coding matrix indication (PMI) from a pre-coding matrix indication set of the base station according to the uplink data and sending the first PMI to the terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for selecting precoding matrix indication, apparatus and system","description":"Embodiments of the present invent provide a method for selecting a pre-coding matrix indication, an apparatus and a system.
