Optimization of PDCCH blind detection method in LTE-A system
In LTE-A system,physical downlink control channel(PDCCH)plays a key role in system scheduling.In order to overcome the high complexity of the conventional blind detection method which leads to the low efficiency of the terminal receiving PDCCH,the improvement is made on the basis of the conventional blind detection method.Using the channel indication information reported by UE terminal to get the current channel condition,and the optimal blind detection level is selected according to the current channel condition,and the blind detection range can be narrowed.When the downlink control information is successfully detected,mark its location,Same PDCCH candidate can be avoided duplicate detection,and optimized the condition of blind multiple DCI detection.By simulation,the improved me effectively reduces the number of times required for blind detection,and improves the efficiency of blind detection.
