摘要

A base station (101) of the present invention includes a sending/ receiving section (1010) for sending/ receiving control signaling information and user data to/from a user device (102), the base station (101) and the user device (102) being wirelessly communicable with each other in a wireless cell (105) of the base station (101); a resource allocation section (1011) for (i) dividing a downlink system bandwidth of a communication system into a plurality of downlink basic bandwidths and (ii) carrying out allocation of resource blocks for uplink control signaling information; a sequence allocation section (1012) for carrying out allocation of a sequence(s) of a resource of the uplink control signaling information in each of an uplink basic bandwidth(s), on the basis of the number of downlink basic bandwidths allocated to the user device (102), so that the uplink control signaling information in each of the downlink basic bandwidth(s) allocated to the user device (102) is fed back to the base station; and a resource scheduling transmission optimizing section (1013) for obtaining the uplink control signaling information of each of the downlink basic bandwidth(s) allocated to the user device (102), on the basis of the sequence(s) thus allocated, and optimally allocating resource blocks of a downlink common data channel to the user device (102).
