Abstract
A radio communication apparatus including: a radio interface; and a processor configured to control the radio interface to transmit a Ranging signal to a base station and to control a transmission power level of the Ranging signal; when the processor controls the radio interface to retransmit the Ranging signal, the retransmission includes a first phase and a second phase, the first phase in which the processor controls the radio interface to retransmit the Ranging signal at substantially a same transmission power level as at the time of initial transmission, or performs substantially a same calculation as that made at the time of the initial transmission of the Ranging signal and retransmits the Ranging signal at the calculated transmission power level, the second phase in which the processor increases the transmission power level and retransmits the Ranging signal at the increased transmission power level.
