1. A method of selecting a transport format of transport channels for transmitting transport blocks in a Code Division Multiple Access (CDMA) mobile communication system including a Radio Link Control (RLC) layer and a Medium Access Control (MAC) layer, wherein the RLC layer contains a plurality of logical channels, converts a received service data unit into a Protocol Data Unit (PDU), and transmits the PDU to the MAC layer through a specific logical channel from among the logical channels, and wherein the MAC layer contains a plurality of transport channels, converts the PDU into a transport block, and transmits the transport block to a physical layer entity through a specific transport channel from among the transport channels, the method comprising the steps of:

  • generating a plurality of subset tables by generating transport formats, which contain logical channel information constituting a corresponding transport channel, for the transport channels;

    classifying the transport formats according to transport block sizes that can be transmitted by corresponding transport channels;

    providing an indicator to each of the transport formats classified according to the transport block sizes;

    converting the PDU into the transport block and detecting a subset table having a transport block size equal to that of the transport block from among the subset tables when the PDU is received through the specific logical channel from the MAC layer after the subset tables are generated; and

    selecting a transport format corresponding to a specific indicator from indicators stored in the detected subset table as a transport format of the transport channel for transmitting the transport block, the specific indicator containing logical channel information of the specific logical channel.
