    Abstract: The present invention relates to a femtocell search method for a handover from a macrocell to a femtocell. The present invention relates to a method for a terminal that accesses a macrocell to search a femtocell in an environment where a plurality of femtocells are overlapped in one macrocell. The terminal searches a femtocell by using a dummy preamble in order to minimize the size of neighbor cell lists broadcasted from the macrocell to the terminal. Therefore, according to the present invention, an MAC overhead can be minimized by eliminating neighbor femtocell lists in a mobile neighbor advertisement (MOB_NBR_ADV) message broadcasted from the macrocell, and the terminal can search a femtocell with a minimum scanning load by checking only a femtocell dummy preamble in a dedicated symbol of the macrocell.

    Abstract: The present invention relates to a method of changing a frequency assignment (FA) status in an improved broadband wireless access system where terminals and base stations can communicate with each other by using a plurality of FAs. In the present invention, the base station changes the status of one of secondary FA into the status of the pFA in order to adjust a load of the primary FA, and communicates with the terminal through the pFA of which status is changed. For this purpose, the base station transmits a MAP information element (IE), which requests the change of the status of the pFA, to the terminal. The MAP IE includes an action code that requests the change of the status of the pFA, and a bit map representing an FA of which status is to be changed. When a response, which represents the completion of the change of the status of the pFA of the base station, is received from the terminal, the base station changes the status of the pFA and communicates with the pFA of the terminal through a new pFA. The status of a previous pFA between the base station and the terminal is changed into the status of the sFA, and the status of one previous sFA between the base station and the terminal is changed into the status of the pFA, so that communication is performed through new FAs. According to the present invention, since the base station can change the status of a specific terminal and FAs in use according to need, it is possible to adjust loads between the FAs. Further, the base station can change the statuses of the FAs in use while continuously maintaining the access of a specific terminal.

    Abstract translation: 本发明涉及一种在改进的宽带无线接入系统中改变频率分配（FA）状态的方法，其中终端和基站可以通过使用多个FA彼此进行通信。 在本发明中，基站将一次辅助FA的状态改变为pFA的状态，以调整主FA的负载，并通过其状态改变的pFA与终端通信。 为此，基站向终端发送请求更改pFA的状态的MAP信息元素（IE）。 MAP IE包括请求更改pFA的状态的动作代码，以及表示要改变状态的FA的位图。 当从终端接收表示完成基站的pFA的状态的响应的响应时，基站改变pFA的状态并通过新的pFA与终端的pFA通信。 基站和终端之间的前一个pFA的状态被改变为sFA的状态，并且基站和终端之间的一个先前的sFA的状态被改变为pFA的状态，从而进行通信 通过新的FAs。 根据本发明，由于基站可以根据需要改变使用中的特定终端和FA的状态，因此可以调整FA之间的负载。 此外，基站可以在持续保持特定终端的访问的同时，改变正在使用的FA的状态。

    Abstract: Provided is an interference avoiding method in a mobile communication system. A base station detects a preamble signal of another base station during an initial setting process or a time frame of a downlink transmission section to detect an adjacent interference base station or receive a report of information on the adjacent interference base station detected by a mobile station from the mobile station. When an adjacent interference base station is detected, the base station sets a common bandwidth from among the entire usage bandwidth as an interference avoiding bandwidth according to a defined rule. The base station allocates a subchannel in the interference avoiding bandwidth to a mobile station in a cell edge area adjacent to a cell of an interference base station.
