This transmission device can notify of a control value pertaining to transmission power without causing an increase in the amount of signaling. A control unit (103) controls transmission power based on a bit sequence notified from a reception device and the association between the bit sequence and a control value pertaining to transmission power; in the association, each bit sequence is respectively associated with a first control value candidate group and a second control value candidate group; when the device is not the subject of cooperative reception, the control unit (103) calculates a transmission power using a control value candidate associated with the notified bit sequence among the first control value candidate group, and when the device is the subject of cooperative reception, the control unit (103) calculates a transmission power using a control value candidate associated with the notified bit sequence among the second control value candidate group.
