摘要： A cell searching apparatus and method in an asynchronous mobile communication system allocates an adjacent SCG to each base station according to adjacent degrees. When a mobile terminal is powered on, the mobile terminal receives PSCs and SSCs from the base stations. Multiple searching of SSCs is then performed based on each slot synchronization followed by a frame synchronization and SCG detection through the first searched SSC. If the detected SCG is not an SCG of a base station to which the mobile terminal belongs, the cell searching apparatus detects an SCG with a large size among the adjacent SCGs and detects an SC by using the greatest SCG. Frame synchronization and SCG detection are therefore quickly performed in a cell searching, resulting in a quick search searching.

摘要： A method for forming an array antenna beam of a mobile terminal periodically compares transmit/receive characteristics of a three-dimensional adaptive beam with transmit/receive characteristics of an omnidirectional beam periodically. A beam direction having better transmit/receive characteristics is then selected. By horizontally rotating an array antenna beam toward up or down at an angle of 360° degrees, a direction having a maximum signal receiving value is searched, and a three-dimensional adaptive beam is set in the searched direction. By using position information of a mobile terminal together with the detected information, a beam direction is set. And, by comparing beam direction information set toward a maximum signal receiving direction with beam direction information set on the basis of position information of a base station/mobile terminal, an optimum beam is selected and formed, thereby improving transmit/receive characteristics of the mobile terminal.
