摘要： A method for transmitting/receiving operation mode information in a broadband wireless access (BWA) communication system is disclosed. A transmission side maps a predetermined preamble pattern to an operation mode, and upon a change in operation mode, transmits a preamble pattern corresponding to the changed operation mode. A reception side receives the preamble pattern, detects an operation mode and a preamble code mapped to the preamble pattern, and acquires information from a frame section received according to the operation mode.

摘要： A method for allocating a frequency to a subscriber station (SS) in handover operation in an Orthogonal Frequency Division Multiple Access (OFDMA) system. In the method, the SS checks safety channel frequencies for a target base station (BS), generates a safety channel frequency request message for requesting allocation of the checked safety channel frequencies, and transmits the safety channel frequency request message. Upon receiving the safety channel frequency request message from the SS, a serving BS allocates frequencies for a requested channel, and transmits an allocation message with the frequency allocation information to the SS. The serving BS transmits a channel allocation request message to the target BS according to the frequency allocation information. Upon receiving the channel allocation request message, the target BS allocates the safety channel frequencies to the SS.
