Abstract
A transmitter transmits a ranging request message to a BS. A receiver receives response information in response to the ranging request message transmitted by the transmitter. A controller transmits the ranging request message from the transmitter at a transmission timing which has been previously set. Subsequently, if the receiver has not received the response information in response to the ranging request message within a predetermined period, the controller retransmits the ranging request message earlier than the transmission timing which has been previously set.
