Abstract
The present invention provides a user terminal that reports channel state information to base station apparatus in order to reduce the overhead of signaling required in beam measurements and to lower the complexity of beam measurements and calculation, and, in this user terminal, a receiving section that receives basis beam reference signals, each included in one or a plurality of basis beams transmitted from the base station, a determining section that determines a leading beam and a secondary beam to combine with the leading beam, based on the basis beam reference signals received, and a transmission section that transmits combination information about combination of the leading beam and the secondary beam to the base station apparatus, are provided.
