Mobile communication terminal and transmission power control method therefor

摘要

A mobile communication terminal receives a control command transmitted on a down-link from a base station and controls a transmission power so that a reception state on an up-link becomes approximately constant at the base station. The mobile communication terminal is provided with a moving speed inferring unit which infers a moving speed of the mobile communication terminal, and a transmission power controller which varies a varying width of the transmission power depending on the moving speed of the mobile communication terminal.
