<P>PROBLEM TO BE SOLVED: To improve transmission efficiency by allowing current reception quality to be recognized accurately in a mobile terminal, in a base station. <P>SOLUTION: A mobile terminal 301 derives channel quality information for showing quality of a channel based on a reception signal received from a base station 302, and derives power control information for controlling transmission power of the base station 302 based on the reception signal received from the base station 302. The channel quality information and the power control information are transmitted to the base station 302 in frame units and in slot units composing the frame, respectively. The base station 302 transmits period designation information which designates a first period to the mobile terminal 301 under control of a base station control station 303, and the mobile terminal 301 updates the first period according to the period designation information. <P>COPYRIGHT: (C)2013,JPO&INPIT |
