摘　　要：LTE物理下行控制信道为整个系统上下行传输分配各种资源,对系统起着非常关键的调度作用。基于PDCCH信道发送与接收流程,根据PDCCH信道结构,详细分析了信道的调度过程、专用搜索空间和公共搜索空间,为终端PDCCH信道接收制定了一种详细的盲检方法,为LTE系统的实际实现提供了理论依据。PDCCH plays a crucial role in the scheduling of LTE system,a variety of resources for the uplink and downlink transmission are assigned.Based on the processes of PDCCH sending and receiving,and according to the structure of PDCCH,a detailed analysis of PDCCH scheduling process is made,search space and common search space are dedicated,and a detailed blind detect method for the receiver of PDCCH is developed at the terminal side,a theoretical basis for the practical realization of LTE system is provided.
