    "patent_abstract": "A method for providing feedback about a MIMO channel between a transmitter and a receiver in a wireless communication system includes receiving a radio signal which includes one or more reference signals according to at least one reference signal configuration known at the receiver and indicating one or more antenna ports associated with the reference signals; estimating the MIMO channel based on measurements on the reference signals; determining a precoding vector or matrix based on the estimated MIMO channel, on one or more vectors or one or more combinations of vectors from at least one port-selection codebook and on a set of precoding coefficients, the port-selection codebook including vectors, each vector being associated with one of the antenna ports and having a single element which is one and the remaining elements being zeros; and reporting, a feedback to the transmitter which indicates the determined precoding vector or matrix.",
    "precision_class": "structural",
    "invention_explanation": "A receiver measures known signals, selects the best antenna combination, and reports that choice so the transmitter can send data more effectively.",
