Abstract
The signaling amount in selecting a plurality of beams is reduced in pre-coding to thereby enhance the throughput. To select a plurality of beams when the pre-coding is applied when notification of a beam number is provided in a feedback signal from a user equipment 102 as a reception station to a radio base station 101 as a transmission station a superior beam number having a high quality rank with small time variation is bound up and fixed for a predetermined time period and notification of only a inferior beam number is provided within the time period. For example to select three beams from six beams first notification of the superior two beam numbers (beam numbers b and c) is provided and the superior beam numbers are fixed for a predetermined time period and then notification of only the inferior one beam number (beam number e) is provided within the predetermined time period for reducing the signaling amount for providing beam number notification.
