摘要： A method for HARQ reordering in Enhanced Uplink Dedicated Channel OF WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reodering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the lub interface and the lur interface.

摘要翻译： 一种用于WCDMA系统的增强型上行链路专用信道中的HARQ重新排序的方法包括以下步骤：将所述软组合缓冲器定位在所述节点B和所述SRNC中的重新排序缓冲器中; 将HARQ实体定位在节点B中; 在SRNC中定位重新排序队列分布实体，重新排序实体和反汇编实体。 本发明采用软组合缓冲器和再调制缓冲器的分离技术，分离模型不仅可以保证分集增益，而且可以减少接收延迟并节省缓冲空间。 提出了三种机制（定时器机制，窗口机制和SBI机制），以防止重新排序缓冲区的阻塞，从而将阻塞降至最低水平，提高接收效率和系统性能。 针对SBI机制，本发明在lub接口和lur接口上提出了新的DCH数据帧结构。
