MAC Frame Structure for Anti-Jamming in OFDMA-Based Wireless Communication System, Communication Method and System Using the Same

摘要

PURPOSE: A base station, a communicating method, and a system thereof using a MAC frame structure for anti-jamming in a wireless communication system based on orthogonal frequency division multiple access are provided to effectively correspond to the change of a hoping channel using an indicator for informing a hoping channel. CONSTITUTION: A base station(100) comprises a transceiver(10) for transmitting and receiving data, a memory(20), and a processor(30). The control information and program executive instruction are stored in a memory. The processor comprises a CIHS generating unit(31), an indicator generating unit(33), and an indicator changing unit(35). The CIHS generating unit hops the control information stored in the memory in a down-link frame. The indicator generating unit is used in order to inform the CIHS information.
