Abstract: PURPOSE: A terminal and a communication method thereof are provided to offer a wireless communication service even if a base station has damage. CONSTITUTION: A processor(132) of a terminal is connected to an RF(Radio Frequency) module(136). When the terminal applies electronic wave interference to a lower terminal, the processor controls the maximum transmission power of an uplink relay area and a maximum transmission power of a downlink access area. The size of the maximum transmission power in the downlink access area is smaller than the size of the maximum transmission power in the uplink relay area. The size of the maximum transmission power in the downlink access area is reduced before radio wave interference is generated. [Reference numerals] (132) Processor; (134) Memory; (136) RF module;

Abstract: PURPOSE: A signaling method for direct communication between the terminals is provided to execute a token management process, an information broadcasting process, a resource management process, a channel measurement process, a flow management process, and a link setup process for direct communication. CONSTITUTION: A transmission terminal transmits a first link setup request message for a direct communication link setup through an RTS(Request To Send) data area to a reception terminal(S1030,S1031). The transmission terminal receives a first link setup response message for setting a direct communication link from the reception terminal through a CTS(Clear To Send) data area(S1032,S1033). The transmission terminal sets a direct communication link from the transmission terminal to a second terminal. The first link setup response message includes direct communication resource information.

Abstract: PURPOSE: A transmission method is provided to transmit a control message when a terminal executes a role of a relay station or a base station. CONSTITUTION: A terminal(200) is operated in multiple modes. The terminal transmits a control message for supporting the multiple modes to a lower apparatus(500)(S520). When a backhaul link is damaged or restored, the control message is transmitted. When the transmission of the control message maintains a relay link, the parameter of a physical layer or an MAC(Medium Access Control) layer is necessary to be constructed again.
