Abstract:
A data processing method for a hybrid ARQ type II/III 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 same radio network, comprising the steps 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 ptotocol 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 to a medium access control common/shared (hereinafter, referred to as a MAC-C/SH), treating a common/shared channel part of the MAC layer; d) transforming the RLC-PDU and the HARQ-RLC-Control-PDU to MAC-PDU and the HARQ-MAC-Control-PDU, respectively, in the MAC-C/SH and allocating a transport format indicator 1 (TFI1) of the MAC-PDU and a transport format indicator 2 (TFI2) of the HARQ-MAC-Control-PDU and transmitting the TFI1 and TFI2 to the MAC-D, and transmitting the MAC-PDU and the HARQ-MAC-Control-PDU to a physical layer of BTS, through a transport channel; and e) forming the TFI1 and the TFI2 in the MAC-D to a transport format combination set (TFC1), then transmitting the TFC1 to the user equipment through a first physical channel, and transforming the MAC-PDU and the HARQ-MAC-Control-PDU to a radio frame, then transmitting the radio frame to the mobile station through a second physical channel.
