    摘要： The present invention relates to a radio resource reallocation method based on the circuit mode. In order to efficiently use the radio resource in the packet-based data transmission system, a circuit mode radio resource is reallocated based on a rearrangement information element and a rearrangement counter information element by using the circuit mode. Accordingly, an unused region of the discontinuous radio resource that can be generated by resource de-allocation and resource change can be eliminated, and a resource allocation mismatch that can be generated by a MAP receiving error can be solved.

    摘要： 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.

    摘要翻译： 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，以便调整主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。

    摘要： The present invention is provided to perform uplink scheduling of a mobile station. In order to perform the uplink scheduling of the mobile station located in a service cell, a base station receives a plurality of interference amounts each corresponding to a plurality of frequency bands associated with an uplink in at least one adjacent cell corresponding to the mobile station from the base station of at least one adjacent cell, respectively, and calculates a plurality of interference values each corresponding to the plurality of frequency bands by using the plurality of interference amounts each corresponding to at least one adjacent cell. In addition, the base station generates scheduling control information corresponding to the mobile station by using the plurality of interference values and transmits the scheduling control information to the mobile station.

    摘要： A terminal transmits control information to a base station by using a periodically allocated dedicated channel. In further detail, the terminal checks control information that needs to be transmitted, detects a priority of the checked control information, and selects control information to be transmitted to the base station based on the detected priority. The terminal forms a PDU by multiplexing the selected control information, and transmits the PDU to the base station.
