Abstract: PURPOSE: A beam tracking method and an apparatus in a wireless communication system are provided to efficiently select a transceiver beam pattern in the wireless communication system, by defining the index retransmission procedure corresponding to the transceiver beam pattern. CONSTITUTION: A base station repetitively transmits the down link reference signal N times in order to select one or more of the optimized down link transceiver beam through the terminal(100). The down link reference signal can be a signal measuring quality of signals such as a synchronizing signal, a preamble signal, and a pilot signal. The terminal measures P number of the optimized down link transceiver beam pair through the down link reference signal. The terminal transmits an up link reference signal which includes P number of the optimized down link transmission beam index information to the base station, M times repetitively(102).

Abstract: PURPOSE: A synchronization acquisition method and apparatus thereof are provided to reduce interference between the terminals which receive services from an infrastructure of a neighbor area and a terminal in an environment where the infrastructure is not operated. CONSTITUTION: When a transmission unit(404) does not receive a preamble signal from a BS(base station), the BS transmits the first preamble signal to a synchronization point. A control unit(402) synchronizes with one or more neighbor terminals by using the first preamble signal. The control unit communicates with the one or more neighbor terminals. The first preamble signal implicitly indicates a result which the BS is collapsed. The first preamble signal is transmitted to a point which is the same as a preamble transmission point of the BS.

Abstract: A common control information transceiving method in a communication system and a system thereof are provided to offer common control information which reduces a signaling overhead, when a coexistence mode where an existing communication system and an advanced communication system coexist and a single mode where the existing system only exists are mixed together. A mobile station obtains synchronization by receiving a preamble, and recognizes a BCH(Broadcasting Channel) area(401). The mobile station decodes common control information included in the BCH area(403). The mobile station recognizes a location of a downlink data burst area of the second communication system according to the decoded results of the common control information.
