Data transmission method for hybrid ARQ type II/III downlink of wide-band radio communication system

A computer readable data recording media having instructions for a data processing method for a hybrid ARQ type II/III on a downlink of a wide-band radio communication system, wherein a serving radio network controller (hereinafter, referred to as a SRNC) which is directly connected to a user equipment to allocate wireless resources to the user equipment and provides services by interlocking with a wireless communication core network in case of a call connection and a controlling radio network controller (hereinafter, referred to as a CRNC) which controls a sharing channel of a radio network are located on the different radio network, comprising the functions of:

• a) generating a radio link control—protocol data unit (hereinafter, referred to as a RLC-PDU) in a radio link control (hereinafter, referred to as a RLC) layer of the SRNC and generating a protocol data unit having RLC-PDU information needed for supporting the hybrid ARQ type II/III based on a header of the RLC-PDU (hereinafter, referred to as a HARQ-RLC-Control-PDU);
• b) transmitting the RLC-PDU and the HARQ-RLC-Control-PDU to a medium access control dedicated (hereinafter, referred to as a MAC-D) treating a general user part of a MAC layer through a logical channel;
• c) transmitting the RLC-PDU and the HARQ-RLC-Control-PDU of the MAC-D of the SRNC to a medium access control common/shared (hereinafter, referred to as a MAC-C/SH) treating common/shared channel part on the MAC layer of the CRNC;
• d) transforming the RLC-PDU and the HARQ-RLC-Control-PDU of the MAC-C/SH of the CRNC to a transmission block and transmitting it to a physical layer of a base station through a transport channel;
• and
• e) processing the transmission block to a radio transmission form in the physical layer of the base station and transmitting it to the base station through the physical layer.
