A composite mobile communication device allowing the reduced amount of hardware and a high-speed data communication is disclosed. One communication circuit uses a local oscillation signal of the other communication circuit to allow a one-frame-two-slot assignment communication on time-division duplex scheme when the other communication circuit does not operate. Since the local oscillation signal of the other communication circuit is used, there is no need of a local circuit to perform the one-frame-two-slot assignment communication. |
