    • PURPOSE: A method for transceiving data having variable lengths in a mobile communication system is provided to use serial numbers having block units and data byte units when radio link protocol(RLP) frames are transmitted, so as to transmit more data to physical channel frames. CONSTITUTION: A multiplexer controller decides transmission orders of more than one service and sizes of data blocks. The multiplexer controller requests data blocks of the services according to priorities. Many radio link protocol(RLP) processors gather the data blocks or data bytes to generate variable length of information bits. A physical layer processor transmits the information bits through a physical channel. Service recognizers and length information are included in the data blocks and the data bytes. A physical layer receiver receives the information bits through the physical channel. The RLP processors separate at least one data block or data byte from the information bits. The RLP processors transmit each data block or each data byte for one of the services.
    • 目的:提供一种用于在移动通信系统中收发具有可变长度的数据的方法,以便在发送无线电链路协议(RLP)帧时使用具有块单元和数据字节单元的序列号,以便将更多数据发送到物理信道帧。 构成:多路复用器控制器决定多个服务的传输顺序和数据块的大小。 复用器控制器根据优先级请求服务的数据块。 许多无线链路协议(RLP)处理器收集数据块或数据字节以生成可变长度的信息位。 物理层处理器通过物理信道发送信息比特。 服务识别器和长度信息包含在数据块和数据字节中。 物理层接收器通过物理信道接收信息比特。 RLP处理器将至少一个数据块或数据字节与信息位分开。 RLP处理器传送每个数据块或其中一个服务的每个数据字节。
