| Abstract: | 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. |
