1. A terminal comprising:
- an antenna configuredto transmit a first random access signal, when the terminal loses a synchronization with a base station, to the base station, andto 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 configuredto obtain a detection result by detecting, when the terminal loses the synchronization with the base station, whether a communication is in progress or not, andto set the period based on the detection result.

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.

8. A communication circuit for the terminal, the communication circuit comprising:
-
a processor configured to generate a first random access signal which is transmitted, when the terminal loses a synchronization with a base station, to the base station, to generate a second random access signal which is transmitted, when a response signal to the first random access signal is not received by the terminal, to the base station after a period, 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; and a memory configured to couple to the processor.

9. A communication method comprising:
-
transmitting a first random access signal, when the terminal loses a synchronization with a base station, to the base station; transmitting 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; obtaining a detection result by detecting, when the terminal loses the synchronization with the base station, whether a communication is in progress or not; and setting the period based on the detection result. - View Dependent Claims (10, 11, 12, 13, 14, 15)
