    • An apparatus and a method for transmitting data are provided to increase the efficiency of a wireless resource by subdividing feedback information and increasing a decoding success rate of the data. An apparatus for transmitting data includes a data coding unit(110), a data transmission unit(130), a feedback information receiving unit(150), and a control unit(170). The data coding unit encodes a plurality of packets in a data link layer and outputs a code for decoding the encoded packet. The data transmission unit transmits the code and the coded packet in a physical layer. The feedback information receiving unit receives feedback information for a decoding state of the encoded packet transmitted from the data transmission unit in the physical layer. The control unit controls the data coding unit based on the contents of the feedback information and the receiving state of the feedback information in the data link layer.

    • A radio packet communication system and a method for allocating radio resources therein are provided to improve the efficiency of a control channel and to increase the number of simultaneously accessing users by reducing the size of control information for packet transmission. A radio packet communication system(10), which uses a header compression transport protocol, includes a header compression part(110), an allocation control part(120), and a resource allocation part(130). The header compression part compresses the header of a packet, and creates a phase information signal containing the phase information of the packet. The allocation control part receives the phase information signal. Based on the received phase information signal, the allocation control part determines a method to allocate radio resources for the packet. In this case, the allocation control part creates the first allocation request signal or the second allocation request signal. If the first allocation request signal is received from the allocation control part, the resource allocation part allocates radio resources for the packet according to dynamic scheduling. In case the second allocation request signal is received, the resource allocation part allocates radio resources for the packet according to persistent scheduling.
    • 提供无线分组通信系统及其中分配无线资源的方法,以提高控制信道的效率,并通过减小用于分组传输的控制信息的大小来增加同时访问用户的数量。 使用报头压缩传输协议的无线分组通信系统(10)包括报头压缩部分(110),分配控制部分(120)和资源分配部分(130)。 报头压缩部分压缩分组的报头,并创建包含分组的相位信息的相位信息信号。 分配控制部接收相位信息信号。 基于接收到的相位信息信号,分配控制部分确定分组的无线电资源的方法。 在这种情况下,分配控制部分创建第一分配请求信号或第二分配请求信号。 如果从分配控制部接收到第一分配请求信号,则资源分配部根据动态调度分配分组的无线资源。 在接收到第二分配请求信号的情况下,资源分配部分根据持续调度分配分组的无线资源。

    • An apparatus and a method for measuring real time performance of the Linux kernel are provided to measure the real time performance easily by measuring the whole delay time including all the sections which is different from a conventional method where task preoccupation delay time is measured for each section. A method for measuring real time performance of the Linux kernel comprises the following several steps. A user inputs instructions including an interrupt cycle via an IO unit(310). An interrupt generator generates an RTC(Real Time Clock) interrupt with a set cycle on the basis of the instructions from the user(320). If a task matched with the interrupt is performed, a controller measures a start time of the task(330). Until the measurement is completed according to the instructions from the user or repeated measurements, the controller repeats the interrupt generation and measurements of the task start times(340). If the measurement is finished, the controller calculates an interval among the measured task start times(350), compares the interval with the interrupt cycle, and outputs a comparison result to the user(360).
