Abstract: PURPOSE: A cell management method and a handover method are provided to increase the accuracy of handover generated in a boundary area of a cell by reducing the size of a cell management message including the information of a neighboring base station. CONSTITUTION: A serving base station broadcasts a neighboring base station notification message to a terminal. The neighboring base station notification message includes the information of a sector, in which a terminal is located, and the information of a base station which locates in a boundary area of a cell. A neighboring base station provides cell tier information to the terminal. When a reception signal of the serving base station is maintained during timeout time set as a predetermined value, the terminal handovers data to an adjacent cell. The predetermined value is smaller than a value except for a variable hysteresis margin of handover set from the reception signal of the neighboring base station.

Abstract: PURPOSE: An Alamouti STBC applying method for enhancing performance of an offshore wind power radio communication control system is provided to apply a MIMO Alamouti STBC(Space-Time Block Coding) to a radio communication based control system, thereby improving transmission quality and reliability of the control system. CONSTITUTION: An Alamouti STBC applying method comprises the steps of: building multiple antennas using the overlay network technology; applying MIMO Alamouti STBC for optimal communication of the multiple antennas. When a control system operates normally, the control system processes valid data by interworking an up line with nets of odd numbers and a down line with nets of even numbers. When failing in forming a wireless link of the up line to a radio device in the front car of a train or detecting an error, the control system reads data of the radio device in the tail car for processing the data as valid data.
