The method may include: a transmitting end receives information transmitted by a receiving end, wherein the information includes information of index of a precoder; the transmitting end selects a precoder from a two-layered codebook based on the information of the index of the precoder; the transmitting end precodes to-be-transmitted data by using the precoder; the transmitting end transmits the precoded data to the receiving end. The technical scheme of the present invention obtains codebooks most matching with channel distribution characteristics of dual-polarized antennas and minimizes performance loss brought by codebook quantization to remarkably improve the performances of precoding systems."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-antenna system and method for transmitting and receiving information in multi-antenna system","description":"Embodiments of the present invention provide a method for transmitting information in a multi-antenna system.
