FIELD: information technology.
SUBSTANCE: device includes: an resource block allocation unit (101) which allocates uplink resource blocks continuous on the frequency axis for respective radio communication mobile stations by frequency scheduling and generates allocation information indicating which uplink resource block has been allocated to which radio communication mobile station device; and an presentation unit (109) which presents a response signal to the radio communication mobile station device in the downlink control channels distributed/presented on the frequency axis while being correlated to the continuous uplink resource blocks according to the allocation information.
EFFECT: maximising the frequency diversity effect on downlink control channels.
