摘要

Control apparatus of power of transmissu00e7o, apparatus of estimation of the path of propagau00c7u00e7o, method of controlling power of transmissu00e7o and method of estimation of the path of propagau00c7u00e7o. The present invention relates to an apparatus for control of transmission power capable of And to reduce an unnecessary transmission power which is consumed in the transmission of symbols, pilot.In the apparatus, a control part of power (109) establishes, based on a number of repetitions of a data signal, a value of transmission power of a pilot signal.For example, the control part of power (109) establishes, based on a reception quality as improved when data signals as replicates according to the number of repetition of a data signal are combined.A value of transmission power of a pilot signal at a level required and sufficient to adapt to a target value of the reception quality of the other end of the communication. A part of the power amplifier (110) amplifies the pilot signal in accordance with the power value D And the transmission is established.
