摘要： A method of acquiring time synchronization and supporting method for the same are disclosed. The present invention is suitable for a receiving side to be synchronized with a transmitting side at an early stage by settling a problem of consuming time in finding to read a current preamble signal inserted, with a uniform, interval in case that the receiving side tunes its time synchronization with that of the transmitting side or measures a signal strength in the OFDM or OFDMA wirelesscommunication system. In an OFDM (orthogonal frequency division multiplexing) or OFDMA orthogonal frequency division multiple access) wireless communication system, the present invention includes the steps of modulating a plurality of reference signals for time synchronization acquisition in a receiving side via at least one of subcarriers and transmitting the at least one reference signal modulated by the at least one subcarrier to the receiving side continuously during at least one symbol time.

摘要： A handover control method in a broadband wireless access system supporting multiple frequency allocations (FAs) is disclosed, in which a serving base station controls a handover. The handover control method includes the steps of receiving (S203) from a mobile subscriber station a handover request message including an identifier of the mobile subscriber station, transmitting (S204) a handover request notification message including the identifier of the mobile subscriber station to a handover target base station, receiving (S206) a handover request notification response message including information for frequency allocation supportable by the target base station, and transmitting (S208) a handover response message including the information for the frequency allocation to the mobile subscriber station. Accordingly, in the broadband wireless access system supporting multiple frequency allocations, the method enables the handover between frequency allocations within one cell or between frequency allocations in different cells.
