The apparatus may include at least one storage device containing a computer program, at least one processing circuit and related control/computing devices. The at least one processing circuit is configured with at least one storage device and computer program to feed back the selected PMI and to receive related signalings of the PMI feedback method. One of the signalings includes the precoder candidate set configuration which defines the subset of precoders in a codebook for each precoder to report PMI next time. The selected PMI is transmitted by the apparatus to the corresponding communication device in the communication network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for bit-adaptive precoding matrix indicator feedback","description":"A method and apparatus for performing precoding matrix indicator (PMI) feedback are provided.
