    • The present invention relates to an uplink synchronization request method in a mobile communication system, a CDMA allocation information element structure thereof, and an apparatus using the same. For this purpose the uplink synchronization request method includes: when uplink traffic is generated, determining whether an uplink synchronization error occurs; when the uplink synchronization error occurs, calculating a timing adjustment value; and transmitting a bandwidth request code including the calculated timing adjustment value to a base station and performing a bandwidth request. According to the present invention, the PSS compares a reference adjustment value and an arrival time of a downlink preamble to calculate uplink synchronization timing and synchronize an uplink of the PSS that requests bandwidth allocation through a bandwidth request ranging process to thereby maximize resource use efficiency in the uplink synchronization.

    • The present invention relates to a beamforming device in an orthogonal frequency division multiplexing access system, and a method thereof. In the method, a switched beamforming algorithm is applied to perform downlink beamforming, and an adaptive beamforming algorithm is applied to perform uplink receiving beamforming. In addition, a half wavelength array antenna is used to simultaneously allocate the same resource to two terminals separately positioned in two different spaces, so as to support spatial division multiple access (SDMA). In this case, since a base station uses channel status information at transmitter (CSIT) for transmitting beamforming and receiving beamforming, the SDMA may be supported without obtaining additional channel status information at receiver (CSIR) when realizing the uplink receiving beamforming.
    • 本发明涉及正交频分复用接入系统中的波束成形装置及其方法。 在该方法中,应用交换波束成形算法来执行下行波束成形,并且应用自适应波束成形算法来执行上行链路接收波束形成。 另外,使用半波长阵列天线来将相同的资源同时分配给分开定位在两个不同空间中的两个终端,以支持空分多址(SDMA)。 在这种情况下,由于基站在发射机(CSIT)处使用信道状态信息来发送波束成形和接收波束形成,所以在实现上行链路接收波束形成时,可以不在接收机(CSIR)下获得附加信道状态信息的情况下支持SDMA。

    • The present invention relates to an uplink synchronization request method in a mobile communication system, a CDMA allocation information element structure thereof, and an apparatus using the same. For this purpose the uplink synchronization request method includes: when up-link traffic is generated, determining whether an uplink synchronization error occurs; when the uplink synchronization error occurs, calculating a timing adjustment value; and transmitting a bandwidth request code including the calculated timing adjustment value to a base station and performing a band-width request. According to the present invention, the PSS compares a reference adjustment value and an arrival time of a downlink preamble to calculate uplink synchronization timing and synchronize an uplink of the PSS that requests bandwidth allocation through a bandwidth request ranging process to thereby maximize resource use efficiency in the uplink synchronization.

    • The present invention relates to a method for generating/changing a transport connection identifier (CID) in a portable Internet System, and a terminal using the same. Accordingly, the present invention provides a terminal including a packet detecting unit, a user input/output unit, a CID managing unit, and a data storing unit. The packet detecting unit determines whether a packet can be classified by a pre-established packet classification rule or a packet cannot be classified by the rules (5304). For the packet that cannot be classified by the pre-established packet classification rule, the user input/output unit receives QoS information from a user (5322, 5324). The CID managing unit generates a new packet classification rule for the unclassified packet (5326), checks a CDD in a data storing unit (5328), the CID having the same QoS class as that of the QoS parameter input through the user input/output unit, and determines whether to generate a new CID (5340) or to add the new packet classification rule to the pre-established CID (5330) depending on the checking result. The data storing unit storing unit Stores the new packet classification rule generated by the CID managing unit and information on the CID (5354).
    • 本发明涉及用于生成/改变便携式因特网系统中的传输连接标识符(CID)的方法,以及使用该方法的终端。 因此,本发明提供了包括分组检测单元,用户输入/输出单元,CID管理单元和数据存储单元的终端。 分组检测单元确定分组是否可以通过预先建立的分组分类规则进行分类,或者分组不能被规则分类(5304)。 对于不能通过预先建立的分组分类规则分类的分组,用户输入/输出单元从用户接收QoS信息(5322,534)。 CID管理单元生成用于未分类分组(5326)的新分组分类规则,检查数据存储单元(5328)中的CDD,CID具有与通过用户输入/输出输入的QoS参数相同的QoS类别 单元,并且根据检查结果确定是否生成新的CID(5340)或者将新的分组分类规则添加到预先建立的CID(5330)。 数据存储单元存储单元存储由CID管理单元生成的新的分组分类规则和关于CID的信息(5354)。
