随着LTE-Advanced系统中,信道在容量和其他性能上的大幅度提高,控制信道技术成为决定数据信道性能好坏的关键因素。通过研究ePDCCH的资源结构,对ePDCCH的传输方式等重要特征进行了分析,并针对控制信道的资源分配问题,对集中式和分布式两种传输类型分别提出了增强型资源粒子组(EREG)到增强型控制粒子(ECCE)的资源映射方式。最后,根据对实际映射关系图的分析和性能评估,验证了所设计的映射方案的合理性和可行性。

As the channel capacity and performance of LTE-Advanced systems are significantly improved, control channel technology becomes a key factor to determine whether the performance of data channel is good. By studying the resource structure, the transmission model of ePDCCH is analyzed. According to the resource allocation problems of control channel, two different modes of enhanced resource element group (EREG) mapping to enhanced control channel element (ECCE) are put forward to support centralized and distributed transmission. Finally, the mapping scheme is proved to be reasonable and feasible by the analysis of the actual mapping diagram.
