    • The present invention relates to an uplink framing method and apparatus in a mobile communication system. After a mobile terminal and a base station are connected to each other in a wireless manner, the base station allocates an uplink radio resource to a medium access control (MAC) layer of the mobile terminal, and then scheduling is performed for each connection in a buffer. Next, a packet data unit (PDU) is generated to satisfy the uplink time constraint and then transmitted to the base station. Therefore, hardware implementation complexity can be minimized in a mobile communication system that should support fast data transmission, and at the same time, a required uplink framing time can be minimized in a system that supports a short frame period.

    • A look-ahead bandwidth requesting method and a mobile terminal using the look-ahead bandwidth requesting method in a mobile communication system are provided. The mobile terminal receives a downlink packet from a base station and transmits the downlink packet to a terminal equipment system. If the downlink packet received from the base station is a TCP packet, the mobile terminal transmits the TCP packet to the terminal equipment system and, at the same time, performs a bandwidth requesting procedure for being allocated a wireless resource through which a TCP ACK packet is to be transmitted to the base station. The bandwidth request is performed by using a random access procedure. The mobile terminal transmits the TCP ACK packet received from the terminal equipment system through the wireless resource that is allocated in advance by using the random access procedure to the base station. As a result, a random access delay is removed or minimized in a mobile terminal for uplink transmission in an asymmetric Internet traffic environment, so that an uplink transmission speed can be increased. Accordingly, a round-trip time of a TCP layer can be reduced, so that a high-speed service can be provided to an application program of a terminal equipment system.
    • 提供了一种在移动通信系统中使用先行带宽请求方法的先行带宽请求方法和移动终端。 移动终端从基站接收下行链路分组,并将下行链路分组发送到终端设备系统。 如果从基站接收到的下行链路分组是TCP分组,则移动终端向终端设备系统发送TCP分组,并且同时执行用于分配无线资源的带宽请求过程,通过该无线资源,TCP ACK分组 将被发送到基站。 通过使用随机访问过程来执行带宽请求。 移动终端通过使用对基站的随机接入过程预先分配的无线资源来发送从终端设备系统接收到的TCP ACK分组。 结果,在不对称因特网业务环境中的上行链路传输的移动终端中移除或最小化随机接入延迟,从而可以增加上行链路传输速度。 因此,可以减少TCP层的往返时间,从而可以向终端设备系统的应用程序提供高速服务。

    • A method of requesting resources, a method of allocating resources, and an apparatus therefor by using bandwidth request ranging in a mobile communication system are provided. The method of allocating uplink resources to a subscriber station by using bandwidth request ranging in a mobile communication system includes: transmitting an uplink channel descriptor (UCD) including code group information to the subscriber station, wherein the code group information is obtained by dividing a bandwidth request code into a plurality of groups and mapping the groups to predetermined data block sizes; receiving a bandwidth request code selected in the subscriber station; determining a code group including the selected bandwidth request code; and allocating a bandwidth through which a data block size corresponding to the determined code group can be transmitted, to the subscriber station. Accordingly, bandwidth request codes are divided into code groups of which bandwidth request codes represent specific block sizes, and the base station that receives the bandwidth request code allocates uplink resources corresponding to the bandwidth request code, so that it is possible to decrease a transmission delay of the uplink traffic.
