Abstract
A terminal including: an antenna configured to transmit a first random access signal, when the terminal loses a synchronization with a base station, to the base station, and to transmit a second random access signal, when a response signal to the first random access signal is not received by the terminal, to the base station after a period, and a processor configured to obtain a detection result by detecting, when the terminal loses the synchronization with the base station, whether a communication is in progress or not, and to set the period based on the detection result.
