    Abstract: In a radio communication system, a downlink frequency band includes a plurality of frequency blocks including one or more carrier frequencies, and one or more frequency blocks are used for data transmission to a single user. A radio communication apparatus for use in the communication system has an evaluation unit evaluating the quality of a received signal for each frequency block and storing plurality of stored quality evaluations of the received signal, a comparison unit comparing the plural quality evaluations of the received signal, and a transmission unit transmitting a predetermined number of the quality evaluations of the received signal over an uplink control channel.

    Abstract: In a radio communication system defining a plurality of bandwidths, mobile terminals of kinds respectively corresponding to the plurality of bandwidths are accommodated in the system, and a minimum transmission bandwidth of the plurality of bandwidths is set as a transmission bandwidth of a downlink common channel. Or, every mobile terminal accommodated in the radio communication system is provided with a capability for processing a bandwidth equal to or greater than a predetermined value, and equal to or more than two transmission bandwidths that are equal to or less than a predetermined value are set as a transmission bandwidth of a downlink common channel. In the latter case, the mobile terminal identifies a bandwidth of a received downlink common channel.

    Abstract: An object is to improve the throughput of a mobile station UE without affecting the coverage of a macrocell in a case where CA is introduced to a HetNet environment. A radio base station eNB according to the present invention is configured to determine whether or not to change the connection destination of a mobile station UE from a small cell #1 to a small cell #2 while the mobile station UE is performing CA by using the macrocell and the small cell #1, based on at least one of the congestion status in each of the small cell #1 and the small cell #2 and the communication quality in each of the small cell #1 and the small cell #2.
