Transmission Power Control Apparatus, Propagation Path Estimating Apparatus, Transmission Power Control Method, and Propagation Path Estimating Method

摘要

A transmission power control apparatus capable of reducing unnecessary transmission power that is consumed in transmission of pilot symbols. In the apparatus, a power control part (109) establishes, based on a repetition number of a data signal, a transmission power value of a pilot signal. For example, the power control part (109) establishes, based on a reception quality as improved when data signals as replicated in accordance with the repetition number of a data signal are combined, a transmission power value of a pilot signal at a level required and sufficient for meeting a target value of the reception quality of the other end of communication. A power amplifying part (110) amplifies the pilot signal in accordance with the established transmission power value.
