1. A device for a user equipment in a wireless communication system, the device comprising:
circuitry, configured to
measure a beamformed second reference signal from a first communication apparatus, the measurement of the second reference signal is according to a first code book, and
generate, based on the measurement of the second reference signal, feedback information as first channel information on a channel between the first communication apparatus and the user equipment,
measure, based on measurement configuration information for the user equipment from the first communication apparatus, a first reference signal in a specific beam corresponding to the first channel information from the first communication apparatus, the measurement configuration information including a measurement indication for the first reference signal, the measurement of the first reference signal including quantization performed according to a second code book different from the first code book; and
generate, based on the measurement of the first reference signal, feedback information as second channel information on the channel between the first communication apparatus and the user equipment.
