FIELD: radio engineering, communication.
SUBSTANCE: spatial channel state information (CSI) feedback technique is incorporated into multiple-input multiple-output mobile communication technology. Spatial channel state information is measured at receiving equipment and then decomposed into components. The components are then quantised using codebook(s) and fed back as multiple indices to transmitting equipment.
EFFECT: improved communication.
