Abstract:
A radio communication device that avoids the trouble arising because of transmission and reception of a signal repeatedly several times, and performs communication appropriately with a radio base station is provided. The radio communication device (100) is the one in which repeated transmission and reception is performed depending on a reception power level of a radio signal transmitted by a radio base station (200) and includes a receiving unit (110) that receives a physical downlink control channel transmitted repeatedly several times; a bundling unit (131) that bundles the physical downlink control channel transmitted several times; and a discontinuous reception controlling unit (140) that detects whether it is necessary to start a timer for managing an active state in a discontinuous reception control based on the bundled physical downlink control channel, and upon detecting that it is not necessary to start the timer, shifts to an inactive state without starting the timer but stopping the already started timer.
