A propagation loss measuring section 207 appropriately changes a measuring method according to the reception type of system informed from a base station so as to measure propagation losses. A propagation loss comparator 209 compares the propagation loss between the respective cells. A transmission slot controller 210 controls a data assembling section 211 and spreader 213 in such a way to transmit a signal to a base station existing in a cell with a smaller propagation loss. A transmission power controller 208 controls a RF section 202 in such a way to transmit a signal with a transmission power value obtained by adding the propagation loss value at each cell to a target reception power value at each base station.
