TRANSMITTING DEVICE AND TRANSMITTING METHOD

摘要

A transmitter capable of properly controlling its transmission power for a DPCH even if a DSCH channel and the DPCH channels are multiplexed. A DPCH transmission power control unit (105) controls the transmission power of a discrete channel so that the transmission power of a section corresponding to the section, where a packet is inserted, of the downlink common channel may be higher than that of the other sections. Amplifier units (104-1 to 104-N) amplify the transmission powers of discrete channels under the control of the DPCH transmission power control unit (105). The discrete channels and the downlink common channel are multiplexed by a multiplexer unit (106). The multiplexed signal is converted to a radio frequency signal by an RF unit (107), and the radio frequency signal is transmitted from an antenna (108) by radio.
